RE: Speech API: first editor's draft posted

Speech API Community Group,Milan Young, Some ideas for extending SRGS include specifying JavaScript events on DOM elements in grammars, as a hypothesis towards the multimodal examples indicated in Section 4 of the HTML Speech Incubator Group Final Report (http://www.w3.org/2005/Incubator/htmlspeech/XGR-htmlspeech-20111206/#use-cases): <item event="html5:click" target="...#element" before="0.5s" after="0.5s" /> or <event type="html5:click" target="...#element" before="0.5s" after="0.5s" /> Also, while SISR includes XML output scenarios (http://www.w3.org/TR/semantic-interpretation/#SI7, http://www.w3.org/TR/semantic-interpretation/#SI7.1, http://www.w3.org/TR/semantic-interpretation/#SI7.2, http://www.w3.org/TR/semantic-interpretation/#SI7.3), it is possible that SRGS and SSML could be enhanced for some specific emergent scenarios.  SSML's <prosody> topics are interesting. I also think that "SpeechRecognizer" and "SpeechSynthesizer" sound good for interface names. By runtime dynamic grammars, I mean those created in the browser, programmatically, for example with JavaScript.  .NET, Java and other speech API's support dynamic grammars; some developers might be accustomed to creating grammars programmatically.  An example use case is a website with a GUI component for displaying items, possibly using XHR or MXHR, and then the page can use JavaScript to create or update a grammar for speech functionality.  In that example use case, the items can each have annotative natural language data, such a website may even be multilingual, and the web application can utilize dynamicism with regard to one or more grammars for voice-based navigation and features.

The Voice Browser Working Group (http://www.w3.org/Voice/)
defines the SRGS and SSML standards.  I suggest that any extensions on incorporating mathematical statements into a speech application are routed through that group.
 
I agree that the TTS name needs work, and the names below seem like a good candidates.  I prefer “SpeechSynthesizer” because it fits well with Recognizer.
 
When you mention “runtime dynamic grammars”, do you mean those created within the browser?  Since I suspect that will complicate the API/implementation, I’d
 like to hear the use case.
 
Thanks

Speech API Community Group,

 

Greetings.  Regarding
http://dvcs.w3.org/hg/speech-api/raw-file/tip/speechapi.html, I wanted to also provide some comments and suggestions for discussion:


 


(1) The interface 'TTS' can be refactored to 'SpeechSynthesis', 'SpeechSynthesizer' or 'SpeechSynth'.


(2) The synthesis interface can include, in addition to text string input, XML string input and document element input for HTML5 and SSML.


(3) During the synthesis of document element inputs, UA's can process substructural elements, as they are synthesized, with options resembling

http://wam.inrialpes.fr/timesheets/docs/timeAction.html .


(4) For XML string and document element input formats, PLS references, CSS speech styling, as well as EPUB3-style SSML-like attributes (http://idpf.org/epub/30/spec/epub30-contentdocs.html#sec-xhtml-ssml-attrib)
 can be recognized by synthesis processors.


(5) With regard to <math> elements, <annotation-xml encoding="application/ssml+xml"> can be recognized by synthesis processors.


(6) <input> types and speech recognition (http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Feb/att-0020/api-draft.html),
 extending HTMLInputElement.


(7) Runtime dynamic grammars.


(8) SRGS/SISR object model.


 


The synthesis and recognition of speech containing mathematical and scientific formulas are interesting topics.  In the comments and suggestions above, the synthesis of mathematical
 and scientific formulas is broached and also interesting is how grammars can be described such that speech recognition transcripts can include XML, hypertext, or MathML mathematical and scientific notation.


 


 

 

Kind regards,

 

Adam Sobieski
