PHONET-A Voice Based Web Technology


Abstract:
Voice based web access is a rapidly developing technology. PhoNET is a solution for these and many other problems faced by the netizens. The basic idea is that using an ordinary phone to browse the web and the primary motivations are: to provide a widely available means for creating new interactive voice applications; addressing needs for mobility; and addressing issues inaccessibility. Basis of the idea are the age old IVR systems used to serve information for the dialers through a pre programmed process. Phonet is a very long journey from the IVRs; it involves the most complex technologies of the century Like Speech Recognition (SR), Text to speech (TTS) conversion and artificial intelligence (AI). This enables a user to be connected to internet as long as he has access to a phone. PhoNET uses the traditional HTML content so the web site need not be rewritten or redesigned. We present a detailed analysis in the most possible simplest way of how the technologies like SR, TTS and AI are integrated to develop a intelligent Platform (PhoNET) to achieve voice based web access which involves Document processing and Document Rendering. In Document Processing we describe two approaches, telephone browsing and transcoding, focusing mostly on the former since that work is more mature. In Document Rendering we present the major problem i.e., the relevance of cognitive thought to text rendering along with its most suitable solution. In the end we examine the challenges and further developments involved in practical application of the proposed technology-The PhoNET.
1. Introduction
Todayâ„¢s telecom business has seen recent growth, especially in bandwidth infrastructure for long distance (LD) and data. The industry is currently experiencing strong growth in the wireless segment as mobile devices prove to be very popular with both consumers and business. An evolving market segment is Internet anywhere, and many companies are trying approaches to present viable products for this market. One approach is Internet access over wireless devices such as cell phones with a screen. However, this method has inherent limitations such as small screen size, lack of a keyboard, the need for a special device (web-enabled phone), the need to rewrite and maintain a special website, and severe bandwidth constraints using wireless data transfer protocols.
Another approach that is becoming popular is voice-based limited Internet access, which overcomes all of the limitations of the wireless data devices but one; they still limit access to the few sites that are re-engineered for voice. They typically deliver content such as news, weather, horoscopes, and stock quotes, etc. over the phone. These companies are called Voice Portals. Voice portals were the first web applications that tried to integrate websites with voice which gave birth to the enterprise based PBX systems.
Our solution, which presents a third option, gives users all of the benefits of the voice portals, yet has complete access to the entire Internet without limitation. With our Voice Internet technology PhoNET, anyone can surf, search, send and receive email, and conduct e-commerce transactions, etc. using their voice from anywhere using any phone, with the more freedom of movement than a standard Internet browser which requires a PC and an Internet connection.
PhoNET technology is faster and cheaper than existing alternatives. Today, only the largest of companies are making their Web sites telephone-accessible because existing technology requires a manual, costly and time-consuming re-write of each page. With the voice internet technology-PhoNET, existing Web pages are used, allowing users to leverage their Web investment. The software dynamically converts existing pages into audio format, significantly lowering the up-front investment a business must make to allow users to hear and interact with their Web site by phone.
2. Motivation
The primary method of access today continues to be the computer, which has certain advantages as well as some limitations. Computers offer a visual Internet experience that is usually rich in content. Some basic computer skills and knowledge are needed to access the Internet. But, computer-based access is proving insufficient for the professional on the move. When in the car or away from the office or computer, accessing the Web is difficult, if not impossible. And, an increasing number of people prefer an interface that allows them to hear and speak rather than see and click or type.
Some existing Internet users have also identified problems with the visual Internet experience. Pages are increasingly full of graphics, advertisement banners, etc., which move, flash, and blink as they vie for attention. Some find this information overload annoying, and lament the delays it creates by severely taxing the available bandwidth.
The "Digital Divide"
While computers and their use are on the rise, theyâ„¢re not ubiquitous yet. A large segment of the population still doesnâ„¢t have access in the United and other parts of the world. Thus, Internet is limited to only a small fraction of the world population; the majority is left out from the Internet. This gap between those who can effectively use new information from the Internet, and those who cannot is known as the digital divide. Bridging this digital divide is the key to ensure that most people in the world have the capability to access the Internet. Making computers ubiquitous is not a very attractive and feasible solution, at least in the near future, because of various barriers. One key barrier is cost, although the price of a computer has come down significantly in recent years. Internet as well, thus bridging the Digital Divide.
The "Language Divide"
Today more than eighty percent of website contents are written in English language. Internet because of language barrier is called "The Language Divide".
As the need for alternative access to the Internet becomes more evident, several technology companies are pursuing solutions. Their products include smart cell phones with visual displays, intelligence built into the handset, and voice-activated Web sites. These products address different aspects of the problems outlined above.
3. The Challenge
To integrate existing technologies, or develop new technologies, to make simple, affordable, alternative Internet access possible.
As the need for an alternative access method to the Internet has become evident, progress continues to be made by technologists to provide such solutions. One key area of focus has been voice-based technology, which would allow a very natural interface for most people, and address the limitations described earlier. A voice interface provides an alternative to the visually based interface. A device such as the telephone provides a readily accessible alternative to the computer.
Several technologies existing today are keys to the solution, but the problem lies in successfully integrating these technologies into useful applications of greater value than their individual components. These technologies include:
Voice Extensible Markup Language (VXML) which is an extension of HTML, the normal language in which Web pages are created. This technology adds voice capability to a Web page. The page can then be displayed, as usual, over a computer, but it can also be presented in audio format with voice navigation.
Speech Language Application Tags (SALT) specification for supporting multimodal communication from PCs, cell phones, PDAs and other handheld devices. For example, input can be voice (such as asking for directions) and output can be data (a map pops up). SALT is a lightweight set of extensions to existing markup languages, allowing developers to embed speech enhancements in existing HTML, XHTML and XML pages. As with Voice XML, applications will be portable - thanks to the separation from the underlying hardware and platform.
Text-to-speech (TTS), which allows text to be converted automatically to synthetic speech. It allows communications between computers and humans through a natural interface, such as speech.
Telephone integration is the key to interface with computers from a remote location. A protocol is needed to communicate with the computer from a telephone using voice. This also includes multimedia integration (e.g. with .wav files).
Intelligent software agents are needed to automate communication between a telephone and a computer, a computer and a Web site, to interpret the contents of a web page, to extract key information that makes sense in audio, to efficiently navigate through web pages, and to manage access to the Internet.
The first technology listed “ Voice XML “ is a very elegant solution that leverages technology specifically developed for audio Internet access. However, it requires that Web sites be customized, or VXML-enabled. This means rewriting the web pages in VXML. According to analysts, today there are more than a billion web pages. Assuming that it takes one hour and costs about $100 to rewrite one page, the cost to voice-enable all sites would be about $100B. Clearly, it will take several years before the majority of popular pages are VXML-enabled. Today, only a very small portion of the total Web pages is voice-enabled using VXML.
The paper presents a solution that successfully integrates the other technologies listed into a useful, audio-based approach for accessing the Internet today. It is independent of the timeline, interest and willingness of content providers to update their pages to be VXML or SALT-enabled.
Another approach is to provide Internet access over wireless devices such as palm pilot or a cell phone with a screen. However, this method has inherent limitations such as the small size of the screen and the need for a special phone. Also there is need to rewrite the website in WML. Todayâ„¢s wireless Internet industry is facing many challenges due to limitation of bandwidth and small screen. The cost of cell phone based Internet access is very high and users do not want to pay high service fee. Also our eyes and fingers are not changing but the devices are getting smaller and smaller. Thus, existing visual based access is going to be even more difficult in future.
4. The PhoNET Solution
An audio Internet Technology that allows users to listen to email, buy on-line or surf and hear any Web site, using a simple and natural interface - an ordinary telephone. No computer is needed.
Subscribers dial a toll-free number, and start accessing the Internet using voice commands. Speech recognition technology in the companyâ„¢s system allows users to give simple commands, such as "go to Yahoo" or "read my email" to get to the Net-based information they want, when they want it, whether theyâ„¢re out on an appointment, stuck in traffic, sitting in an airport, or cooking dinner. Theyâ„¢ll be able to quickly locate information, such as late-breaking news, traffic reports, directions, or anything else theyâ„¢re interested in on the World Wide Web. Our product Phonet has the capability to automatically down load web contents, filter out graphics, banners and images. It then renders extracted texts into concise, meaningful and very suitable in audio format texts before using TTS to convert into speech. PhoNET also converts the rendered texts into other languages in real time.
5. Technology Overview.
The idea of listening to the Internet may at first sound a bit like watching the radio. How does a visual medium rich in icons, text, and images translate itself into an audible format that is meaningful and pleasing to the ear? The answer lies in an innovative integration of three distinct technologies that render visual content into short, precise, easily navigable, and meaningful text that can be converted to audio.
The technologies and steps employed to accomplish this feat are:
Document Processing
1. Speech recognition
2. Text-to-speech translation, and
Document Rendering
3. Artificial Intelligence

The PhoNET platform acts as an Intelligent Agent (IA) located between the user and the Internet (Figure 1). The IA automates the process of rendering information from the Internet to the user in a meaningful, precise, easily navigable and pleasant to listen to audio format. Rendering is achieved by using Page Highlights (a method to find and speak the key contents on a page), finding right as well as only relevant contents on a linked page, assembling right contents from a linked page, and providing easy navigation. These key steps are done using the information available in the visual web page itself and proper algorithms that use information such as text contents, color, font size, links, paragraph, and amount of text. Artificial Intelligence techniques are used in this automated rendering process. This is similar to how the human brain renders from a visual page; selecting the information of interest .
The IA includes a language translation engine that dynamically translates web contents from one language into another in real time.
The platform incorporates the highest quality speech recognition and text to speech engines from third party suppliers.
ThePhoNET architecture is shown in Figure 2. The process starts with a telephone call placed by a user. The user is prompted for a logon pass phrase. The users pass phrase establishes the first connection to the Web site associated with that phrase and loads the first Web page. The HTML is parsed, as described later, separating text from other media types, isolating URL from HTML anchors and isolating the associated anchor titles (including ALT fields) for grammar generation. Grammar generation computes combinations of the words in titles to produce a wide range of alternative ways to say subsets of the title phrase. In this process simple function words (i.e., "and," "or," "the," etc.) are not allowed to occur in isolation where they would be meaningless. Browser control commands are mixed in to control typical browser operations like "go back "and "go home" (similar to the typical browser button commands). This process typically takes about a second. At the same time, the Web document is described to the user, as discussed later. The user may then speak a navigation or browser command phrase to control browsing. Each user navigation command takes the user to a new Web page. If the command is ambiguous the dialog manager collects the possible interpretations into a description list and asks the user to choose one.
6. Document Processing
Document analysis is performed in the HTML parser, grammar generator, and Hyper Voice processor modules. The typical HTML Web page is first parsed into a list of elements based mostly on the HTML tags structure. Some elements are aggregations (tables, for instance) but the element list is not a full parse tree, which we found was not needed and in some cases actually complicates processing. Images, tables, forms and most text structure elements like paragraphs are recognized and processed according to their recognized type. Much of the effort in building a robust HTML processor is dealing with malformed HTML expressions such as unclosed tag scope, overlapping tag scopes, etc. Unfortunately space does not allow for fully addressing this issue here. The location of each image is announced along with any associated caption. This feature can be disabled on a site-by-site basis when the user does not want to hear about images. Tables are first classified according to purpose, either layout or content. Most tables are actually used for page layout which can be recognized by the variety and types of data contained in the table cells. Data tables are processed by a parser according to one of a set of table model formats that Phone Browser recognizes. This provides primarily a simple way of reading the table contents row by row, which is often not very satisfying. Alternatively a transcoder can be used to reconstruct the table in sentential format. While large vocabulary dictation speech systems are available, most require speaker training to achieve sufficiently high accuracy for most applications. Phone Browser is intended to be immediately usable without training so dictation is not yet supported. This also implies that creating arbitrary text for messaging is also not yet supported. One additional type of form input is an extension to HTML. A GSL (Grammar Specification Language) or JSGF (Java Speech Grammar Format) specification can be inserted into an HTML anchor using an attribute tag (currently LSPSGSL). Using this method an application can specify an elaborate input grammar allowing many possible sentences to address the associated hyperlink and construct a GET type form response where the QUERY_STRING element is constructed by inserting the speech recognition text results. Grammar specifications written this way may represent many thousands of possible sentence inputs giving the end user great speaking flexibility.
7. Document-Rendering
Rendering-Definition
Information technology uses this term ËœRenderingâ„¢ refers to how information is presented according to the medium, for example, graphically displayed on a screen, audibly read using a recording device, or printed on a piece of paper.
In the context of voice/audio Internet, Web content rendering entails the translation of information originally intended for visual presentation into a format more suitable to audio. The Rendering Problem
Computers possess certain superhuman attributes, which far outstrip that of mortal man”most notable are their computational capabilities. The common business spreadsheet is a testament to this fact. Other seemingly more mundane tasks, however, present quite a conundrum for even the most sophisticated of processors. Designing a high-speed special purpose computer capable of defeating a grandmaster at chess took the computing industry over 50 years to perfect. Employing strategic thinking is not a computer™s forte. That is because in all the logic embodied in their digitized ones and zeroes, there is no inherent cognitive thought. This one powerful achievement of the brain along with our ability to feel and express emotion separates the human mind from its computerized equivalent”the centralized processing unit (CPU).
The relevance of cognitive thought to text rendering may not be immediately obvious but it is one of the major challenges faced when attempting to present information designed for one medium and rendering it to another. This is because there are no hard and fast objective rules to follow. Computers are very good at following instructions when they can be reduced to very objective decision points. They are not so good when value judgments are involved. A human being can readily distinguish a cat from a dog, or a relevant news link on a Web page from a link for an advertisement. Solving the problem
To solve the rendering problem, some intelligent techniques must be applied. The relevant data must be selected, navigated to its conclusion, and reassembled for presentation by a different medium. All of this must be done for all web pages, dynamically, in real-time and in an automated fashion. We have used an Intelligent Agent (IA) that uses various intelligence techniques including artificial intelligence.
Upon selecting an item of interest it is common to have to navigate to another Web page to read all the data of interest (just like in the newspaper example). To do so we click on a Web link. When following a page link the problem of continuity of thought is encountered because almost assuredly the newly linked page contains data in addition to the thread of information we are attempting to follow. In order to maintain continuity with the item from the previous page a contextual correlation must be made. Once again, this cognitive process poses a formidable challenge for the computer and requires application of Intelligent Agent (or artificial intelligence) principles to solve.
Simplifying for speech
The first step involves dynamically removing all the programming constructs and coding tags that comprise the instruction to a Web browser on how to visually render the data. HTML, CHTML, XML, and other languages are typically used for this purpose. Because the data is now being translated or rendered to a different medium, these tags no longer serve any purpose.
It is doubtful that every single data item on a page will be read. Just like reading a newspaper, we read only items of interest and generally skip advertisements completely. Thus, we need to automatically render important information on a page and then when a topic is selected, only the relevant information from the linked page corresponding to the selected topic needs to be presented. . Rendering is achieved by using Page Highlights (using a method to find and speak the key contents on a page), finding right as well as only relevant contents on a linked page, assembling right contents from a linked page, and providing easy navigation.
Finding and Assembling Relevant Information
To find relevant information, the Intelligent Agent (IA) uses various deterministic and non-deterministic algorithms that use contextual and non-contextual matches, semantic analysis, and learning. This is again very similar to how we do use our eyes and brain to find the relevant contents. To ensure real-time performance, algorithms are simplified as needed yet producing very satisfactory results. Once relevant contents are determined, they are assembled in appropriate order that makes sense when listen to in audio or viewed on a small screen.
A content rich page with a small number of links makes rendering and navigation easy since there are only a few choices, and one can quickly select a particular topic or section. Rendering to a new medium
The two key media for rendering into are audio using any phone and visual using a cell phone screen or PDA. There is a good synergy between these two modes from rendering standpoint. Both need small amount of meaningful information at a time that can be heard or viewed at ease with easy navigation. This is achieved by using Page Highlights mentioned above and finding relevant contents, column at a time like we do when we read a news paper or website.
The same column of text can be displayed on a small screen that can be viewed at ease as a small screen can easily display a column; but not a whole page. The contents are then automatically scrolled using various speeds and hence can easily be viewed and absorbed at ease. This is what results a Micro Browser or true wireless Internet that does not need any re-write of the website and presents contents at ease in a meaningful way.
8. Applications
This technology can find applications for Service Providers, Businesses and governments in the following areas:
For Service Providers -
Surf and browse the Web ¢
Email (send, receive, compose, copy, forward, reply, delete and more) ¢
Search the Web ¢
Voice Portal Features such as News, Weather, Stock Quotes, Horoscopes and more.
For Businesses
Airline reservations and tracking
Package tracker
Reservations
ECommerce
Customer service
Alert service
Order Confirmation
CRM Applications
For Governments
All key benefits for Businesses Plus
Easy Accessibility to all Government contents
More efficient communication between Government and citizens, Government and businesses, and between Government departments.
Meeting Government obligation to bridge the Digital and Language Divides (with automatic translation of Internet content from English to any other language and vice-versa.), and providing Internet to elderly, visually impaired and blind people in a very simple and cost effective way.
9. Future Work
Implementation and results of this new proposed technology depends on the developments in the field of speech recognition and artificial intelligence. The major challenge of this technology is its complexity which comes with a high price tag. But it is not far more than the complexity and cost involved in voice enabling a web site using the present technologies. We believe that Voice/speech based interface options will become an important part of the overall solution to access the Internet content. And an automated approach to Voice-Enable or create Voice Portals would be most practical and more common way than rewriting web contents in different languages and maintaining multiple version of the web sites.
10. Conclusion
We considered the possibility of accessing web through an ordinary phone. We presented a new technology which provides a true audio Internet experience. Using an ordinary telephone and simple voice commands, users will be able to surf and hear the entire Internet for the information they desire. A computer is not needed. Any web page will be accessible, but not limited to sites written with Wireless Application Protocol, and pages that are specially written in Voice Extensible Mark-up Language (VXML). We presented a detailed analysis of how the technologies like SR, TTS and AI are integrated to develop a intelligent Platform (PhoNET) to achieve voice based web access. We presented the major problems involved in Document processing and document rendering along with solution.

1.INTRODUCTION

Today’s telecom business has seen recent growth, especially in bandwidth infrastructure for long distance (LD) and data. The industry is currently experiencing strong growth in the wireless segment as mobile devices prove to be very popular with both consumers and business. An evolving market segment is “Internet anywhere,” and many companies are trying approaches to present viable products for this market.

However, this method has inherent limitations such as small screen size, lack of a keyboard, the need for a special device (web-enabled phone), the need to rewrite and maintain a special website, and severe bandwidth constraints using wireless data transfer protocols.
Another approach that is becoming popular is voice-based limited Internet access, which overcomes all of the limitations of the wireless data devices but one; they still limit access to the few sites that are re-engineered for voice. They typically deliver content such as news, weather, horoscopes, and stock quotes, etc. over the phone. These companies are called “Voice Portals.” Voice portals were the first web applications that tried to integrate websites with voice which gave birth to the enterprise based PBX systems.
Other solutions, such as Personal Digital Assistants, phones with display screens and other Internet appliances, are available, but have limitations. Users must have special hardware with intelligence built in, and often must view the Web through small, difficult-to-read screens. Such devices are often expensive, as well.
Our solution, which presents a third option, gives users all of the benefits of the voice portals, yet has complete access to the entire Internet without limitation. With our Voice Internet technology phoNET, anyone can surf, search, send and receive email, and conduct e-commerce transactions, etc. using their voice from anywhere using any phone, with the more freedom of movement than a standard Internet browser which requires a PC and an Internet connection.

And, an increasing number of people prefer an interface that allows them to hear and speak rather than see and click or type.
The computer-based Internet experience also does not meet the needs of another segment of the population – the visually impaired. Neither visual displays of information, nor keyboard-based interactions naturally meet their needs, and this segment is often unable to benefit from all that the Information Age has to offer.
Some existing Internet users have also identified problems with the visual Internet experience. Pages are increasingly full of graphics, advertisement banners, etc., which move, flash, and blink as they vie for attention. Some find this “information overload” annoying, and lament the delays it creates by severely taxing the available bandwidth.
The "Digital Divide"
While computers and their use are on the rise, they’re not ubiquitous yet. A large segment of the population still doesn’t have access in the United and other parts of the world. Thus, Internet is limited to only a small fraction of the world population; the majority is left out from the Internet. This gap between those who can effectively use new information from the Internet, and those who cannot is known as The digital divide. Bridging this digital divide is the key to ensure that most people in the world has the capability to access the Internet. Making computers ubiquitous is not a very attractive and feasible solution, at least in the near future, because of various barriers. One key barrier is cost, although the price of a computer has come down significantly in recent years. Insufficient visual Internet Infrastructure is another barrier in many countries and it will take a while to build such infrastructure. Other consumers have a basic distaste for complex technology, which prevents them from accessing Web-based information via a computer. A more natural, less cumbersome way to interface with the net would provide them an opportunity to experience the Internet as well, thus bridging the Digital Divide.
