ISSUE 1

Summary

<html>ISSUE 1: interaction between the 'voice-volume' property and the loudness of 'cue' properties</html>

Status

<html>CLOSED [

Accepted

]</html>

Resolution

Working Group consensus: clarify multiple informative statements that misleadingly firmly associate SSML features with CSS-Speech properties + correct editorial glitch which results in a whole paragraph being normative rather than informative + improve (shorten) the said informative paragraph (as per the email proposal). (Note, WG was waiting for commenter's reply, see http://lists.w3.org/Archives/Public/www-style/2011Nov/0719.html or http://logs.csswg.org/irc.w3.org/css/?date=2011-11-23 )

Comment 7

http://lists.w3.org/Archives/Public/www-style/2011Oct/0511.html (commenter's agreement ⇒ Verified)

Remarks

voice-language solution, similar to http://dev.w3.org/csswg/css3-fonts/#font-language-override-prop, as illustrated by Fantasai:

voice-language: auto | <language-code> | inherit; inherited: yes; computed value: as specified; with auto ⇒ The used value is taken from the language of the selected element, or some UA-chosen value if unknown. The computed value is the keyword 'auto'.

REMARK

commenter is not available to confirm, but the WG resolution is aligned with a well-established design decision since the very early days (pre-2004 Working Draft) of the CSS Speech Module Level 3, so we think that the issue can be confidently marked Verified.

Issue 7

Summary

<html>ISSUE 7: use of generic SPAN element in voice-stress example and client-side use question</html>

Status

<html>CLOSED [

Accepted

]</html>

Resolution

Working Group consensus: make a minor editorial improvement so that the example uses 'em' instead of 'span'. However, the HTML default user-agent stylesheet remains out-of-scope (See http://lists.w3.org/Archives/Public/www-style/2011Oct/0607.html or http://log.csswg.org/irc.w3.org/css/?date=2011-10-19 )

Testing, Reference Implementations

Existing Prototypal or Semi-Complete Implementations

(support for “aural” and/or “speech” stylesheets, as per the CSS2.1 appendix and/or the previous CSS3-Speech drafts, respectively)

Note that this topic is tracked on the public CSS emailing list (feel free to contribute there): http://lists.w3.org/Archives/Public/www-style/2011Mar/0389.html

Opera: implements some of CSS3-Speech (and non-deprecated CSS2.1 Aural Stylesheets features): http://www.opera.com/docs/specs/presto25/css/properties/ (the documentation lists speech properties up to Opera engine Presto v2.5, see here: http://www.opera.com/docs/specs/productspecs/ )
EmacSpeak: implements CSS Aural Stylesheets: http://emacspeak.sourceforge.net
FireVox: implements some CSS Speech features (has its own CSS parser, because Firefox doesn't support CSS Speech/Aural features), see http://www.firevox.clcworld.net/demos/css_demo.html and http://clc4tts.clcworld.net/css_technical.html
WebKit: implements support for the “speak” property in its core, and I think that there is platform-level support through the accessibility layer (Mac OS X only ?). See http://trac.webkit.org/browser/trunk/LayoutTests/platform/mac/accessibility/css-speech-speak.html and https://bugs.webkit.org/show_bug.cgi?id=46827 (partially supported by VoiceOver in the iOS5 betas)
FormsPlayer (now “ubiquity-xforms”, included in “backplanebx”): for Internet Explorer, provides prosody control via CSS properties (voice, volume, rate, pitch). See http://www.google.com/codesearch?q=speak+package:http://ubiquity-xforms-cpp\.googlecode\.com and http://code.google.com/p/backplanebx/source/browse/XFormsProcessor/content/XFormsProcessor/chrome/
