 Co-chaired by Jim Larson and Scott McGlashan .
Speech Interface Framework
 VoiceXML 1.0
 VoiceXML 2.0
 VoiceXML 2.1
 Voice XML 3.0
 Speech Recognition Grammar Specification (SRGS) 1.0
 Speech Synthesis Markup Language (SSML) 1.0
 Speech Synthesis Markup Language (SSML) 1.1
 Call Control XML (CCXML)
 State Chart XML (SCXML)
 Semantic Interpretation (SISR) 1.0
 Pronunciation Lexicon Specification (PLS) 1.0
Voice XML(VoXML)
 Version 1.0 - designed for creating audio dialogs .
 Version 2.0 - uses form interpretation algorithm(FIA).
 Version 2.1 - 8 additional elements.
 Version 3.0 - relationship between semantics and (31 August 2010) syntax.

 Tampered prompts
 Grammar specifying alternative words that the user can speak in response to the question.
 Instructions to the text-to-speech synthesizer about how to say words and phrases.

Speech Recognition Grammar Specification(SRGS)
 Version 1.0 -for specifying grammars of each user input to a speech application.
Speech Synthesis Markup Language(SSML)
 Version 1.0 -for specifying the rendering of synthesized speech to the user.
 Version 1.1 - enhancement of SSML 1.0 for better support of the world's languages including Asian, Eastern European, and Middle Eastern languages.
Call Control XML(CCXML)
For specifying call control functions
State Chart XML(SCXML)
Execution environment based on CCXML and Harel State Tables.
 Semantic Interpretation Speech Recognizer(SISR)
Version 1.0 - For specifying possible translation of text from the output of a speech recognizer.
Pronunciation Lexicon Specification (PIS)
Version 1.0 - Syntax for specifying pronunciation lexicons to be used by Speech Recognition and Speech Synthesis.
Model Architecture
Applications

 It can be divided into three categories :
 Web Browsing
 Limited information Access
 Spoken Dialog Systems
Web Browsing
 Browse any web pages using speech input.
 Parsing for the purpose of voice recognition done when the page is accessed.
 May or may not produce a voice feed back.
Limited Information Access
 Useful information in limited domains like weather in a city, checking stock updates etc.
 Audio feed back
Spoken Dialog Systems
 Client-server architecture is used
 Used for connecting to a remote server by a Java applet(client).
 Examples are connecting to email servers
Benefits
 Voice is a very natural user interface which speeds up browsing.
 Less space requirements.
 Portable voice browsers can also be implemented.
 Practical interface for functionally blind users.
 Users can browse web while keeping there hands and eyes for other jobs
Future
 Voice browsing will become visual(Multi-modal)
 Can be integrated to an OS
 Integrated to every application.
Conclusions
 Browser technology is changing very fast these days and we are moving from the visual paradigm to the voice paradigm.
 Voice browser is the technology to enter this paradigm.
 Voice browser is a device which interpret voice input and generate voice output.
