RE: Speech API: first editor's draft posted

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
