Voice Browser,it is a kind of browser that responds with the voice and even takes input from the user through voice and processes the input using standardized VoiceXML.It is W3C certified project.
3. Introducing Voice Browser
As the name suggests Voice Browser uses
Voice to navigate a web application.
This works similar to graphical web
browser, as a result any telephone can be
used to access appropriately designed
Web-based services.
In essence, a voice browser is a software
application that presents an interactive
voice user interface
4. Differences Between
Graphical and Voice Browser
Graphical
browsing is
passive.
Keyboard
commands are
required for
Graphical
browser.
Voice browsing
is an active
process.
Voice is medium
to communicate
with an
application.
5. WHY A VOICE BROWSER?
Use of the hands during browsing might
prove inconvenient or impossible. Voice
input is a natural solution for such ands-
busy situations.
Even in standard browser applications,
using voice input is simply more fun than
the alternatives.
Browser replaces the mouse in most
instances to enable hands-free browsing.
6. Use Cases:
Easy to use - for people with no knowledge or fear
of computers.
Many companies offer services over the phone via
IVR . With the advent of Voice Browsers ,they will
become next generation Voice Web portals to the
company's services and related websites, whether
accessed via the telephone network or via the
Internet.
7. W3C STANDARDS
The World Wide Web Consortium (W3C)
develops interoperable technologies
(specifications, guidelines, software, and
tools) to lead the Web to its full potential
as a forum for information, commerce,
communication, and collective
understanding.
9. Speech Recognition Grammar
Specification (SRGS)
A document language that can be used by
developers to specify the words and
patterns of words to be listened for by a
speech recognizer or other grammar
processor.
10. SEMANTIC INTERPRETATION
FOR SPEECH RECOGNITION
The recognition process matches an
utterance to a speech grammar, building a
parse tree as a byproduct.
There are two approaches to harvesting
semantic results from the parse tree:
Annotating grammar rules with semantic
interpretation tags.
Representing the result in XML.
11. PRONUNCIATION LEXICON
SPECIFICATION
A representation of phonetic information
for use in speech recognition and
synthesis.
Application developers sometimes need to
ability to tune speech engines, whether
for synthesis or recognition.
12. VOICEXML
VoiceXML is a dialog markup language
designed for telephony applications, where
users are restricted to voice and DTMF
(touch tone) input.
There are other languages: VoXML.
14. FUNCTIONALITY
Communication from the user to the system is made by
issuing voice commands.
A grammar set is defined to recognise these commands.
There are few rules that are used to navigate the
webpage.
Below are a few administrative controls:
Speak
Where am I?
What is my home page?
15. APPLICATIONS
Google’s-Google now can be considered as
one of the best delivered application as
of yet.
Though it is not as functional as a
graphical browser, it is somewhat similar.
Some other applications are:
IOS’s: Siri
Windows: Cortana
17. CONCLUSION
In order to make technology more familiar to the
user its access should be made much easier.
It is know that visual internet access experiences
various limitations such as people who are
physically handicapped (especially blind users)
cannot use keypads or touch screens for giving
instructions.
Above all these limitations today’s generation
demands to use internet independent of PC’s and
also hands free access to it.
For this VOICE BROWSING is an intelligent idea.
