The document discusses PHONET, a voice-based web access system. PHONET uses speech recognition to convert voice commands to text, text-to-speech conversion to audibly render web pages, and artificial intelligence to act as an "intelligent agent" that automates accessing and presenting information from the internet in an audio format. The system allows users to access websites, search engines, email and more using only voice commands over a telephone. It integrates complex technologies but provides a simpler interface that can be used by anyone with a phone, regardless of reading ability or internet access.

3. ABSTRACT
3
Voice based web access is a rapidly developing
technology. PHONET is a solution for this
technology
PHONET is used to make information accessible to
users who may not be able to read or write, or who
do not have access to the internet

4.  Unlike a computer interface , a voice interface needs
no keyboard, no mouse, freeing from these barriers
to access internet
 It requires no training
 It is accessible to anyone with a telephone

5. INTRODUCTION
5
 PHONET involves the most complex technologies
Like Speech Recognition (SR), Text to speech (TTS)
conversion and Artificial Intelligence (AI).
 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.

6.  Document Processing consists of two approaches
i.e., telephone browsing and transcoding
 In Document Rendering we present the major
problem i.e., the text rendering.
 The companies which deliver contents such as news,
weather, horoscopes, and stock quotes, etc. over the
phone, are called “Voice Portals”.
6

7.  Voice portals were the first web applications that
tried to integrate websites with voice.
 With the Voice Internet technology PHONET,
anyone can surf, search, send and receive email, and
conduct e-commerce transactions, etc.
 PHONET technology is faster and cheaper.
7

8.  The PHONET platform acts as an “Intelligent
Agent” (IA) located between the user and the
Internet .
 The IA automates the process of rendering
information from the Internet to the user in a
meaningful, precise and pleasant to listen audio
format
8

9. MOTIVATION
9
 When we are in the car or away from the office or
computer, accessing the Web is difficult.
 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.

PROPOSED SYSTEM

PROPOSED PLAN FOR THE
WORKING OF PHONET

11. WORKING PRINCIPLE
11
 Subscribers dial a toll-free number, and start
accessing the Internet using voice commands.
 Speech Recognition technology in the
company’s system allows users to give simple
commands, such as "go to Google" or "read my
email" to get to the Net-based information they
want.

12.  When the user sends request to access the
internet, the request goes to the voice browser.
 If the request is voice, speech Recognition
converts voice into text.
 They will be able to quickly locate information,
such as breaking news, traffic reports,
directions, or anything interested in the World
Wide Web.
12

13.  Using text-to-speech technology, an "intelligent agent"
will read the requested via ainformation
process
out loud
the user’s voicecomputerized voice, and
commands.

14. The Technologies employed are :-
1. Speech processing
2. Text-to-speech translation
3. Artificial Intelligence
4.Language Translation

15. 1. SPEECH PROCESSING
 Speech processing is the study of speech signals and the
processing methods of these signals.
 The speech signals are processed in digital representation.

SPEECH PROCESSING REPRESENTATION

16. 2.TEXT TO SPEECH TRANSLATION
 Text to speech translation is the process by which
conversion of text data to speech signals takes place
Fig4:- TEXT TO SPEECH CONVERSION

17. 3. ARTIFICIAL INTELLIGENCE
 It is the intelligence exhibited by software.
Fig5:- ARTIFICIALINTELLIGENCE 17

18.  PHONET Offer the promise of Allowing everyoneto
access web based services from any phone.
 Users will be able to choose whether to respond by a
key press or a spoken command
 The main plan is
1. Accept the voice commands
2. Output in audio format
18

19. 4.LANGUAGE TRANSLATION
19
 The IA includes a language translation engine that
dynamically translates web contents from one
language into another in real time.
 Thus, a Hindi speaking person can ask to surf an
English website in Hindi - the Intelligent Agent
would access the English website, extract the
content of the website and translate it in Hindi and
read it back to the user in Hindi.

20.  Grammar processing continues with compilation and
optimization where redundancies are eliminated.
The word vocabulary associated with the grammar is
further processed by a Text-To-Speech (TTS)
pronunciation module that generates phonetic
transcriptions for each word of the grammar.
 Since the TTS engine uses pronunciation rules it is
not limited to dictionary words. The grammar and
vocabulary are then loaded into the speech
recognizer. This process typically takes about a
second. At the same time, the Web document is
described to the user.
20

21.  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 and then reading.
21

22.  The IA includes a language translation engine that
dynamically translates web contents from one
language into another in real time. Thus, a Hindi
speaking person can ask to surf an English website
in Hindi - the Intelligent Agent would access the
English website, extract the content of the website
and translate it on the fly in Hindi and read it back to
the user in Hindi.
22

23. ADVANTAGES
23
 The possibility of accessing web through an
ordinary phone
 Email (send, receive, compose, copy, forward, reply,
delete and more)
 Airline reservations and tracking

24. DISADVANTAGES
24
 Complexity in Hardware interface
 All the users should know English
language , as the user interface will be
provided in English

25. CONCLUSION
25
 It is 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
information they desire
 Any web page will be accessible, but not
limited to sites as written with Wireless
Application Protocol.
