I could imagine a system where the JS access to the TTS is shared across a consistent priority model to that same TTS by the screen
reader, so that both can interact with it successfully; however, use concepts of priority, interrupt ability, blocking, and so on to
facilitate a seamless interaction.

This does however bring up the classic argument over self voicing versus screen reading; however, to that end it's imaginable that
one can have a hybrid approach whereby including a simple .js file from somewhere else on the web, suddenly enables your application
to speak, and that .js file could either contain self voicing capabilities or a screen reader of sorts.

Take care,
Sina

"I think this would be a great addition to the realm of existing assistive technologies. Having Javascript API access to the OS's
built-in TTS would enable us to generate audio descriptions for videos directly from the web page in conjunction with ARIA live
regions, for example. Such a capability should be togglable by the user and/or disabled if a screen reader is detected (although a
shortcut key-based approach may be sufficient)."

	Agreed, it really would open up some terrific possibilities. Handling the relationship with screen readers will certainly be
a challenge, as I can imagine times when both/neither would be desirable from the user's point of view.

Léonie.

Hi David,
I think this would be a great addition to the realm of existing assistive technologies. Having Javascript API access to the OS's
built-in TTS would enable us to generate audio descriptions for videos directly from the web page in conjunction with ARIA live
regions, for example. Such a capability should be togglable by the user and/or disabled if a screen reader is detected (although a
shortcut key-based approach may be sufficient). The power of this feature will depend on how many of OS's built-in TTS properties
will be exposed by the browser to the Javascript developer, eg voice rate, tone, pitch, voice, person, volume etc.

Is Firefox going to be one such browser? :) Thanks, Victor

  Hi all,

What do you think about having browsers provide built-in text-to-speech capability to web content? While I imagine a declarative
approach might be quite interesting I think we can go farther faster with a JavaScript API approach. The main two concerns I have
are:

1. We don't want to encourage unpolished aural interfaces.
2. We don't want to conflict with traditional screen readers.

The biggest potential I see is:

1. Innovation in Aural interfaces. The same kind of innovation we see happening in visual DHTML interfaces.
2. TTS solutions in places, and on devices where traditional screen readers are problematic. For example, perhaps on some mobile
devices that are currently not accessible.
3. The TTS can be done in the browser, on the native platform (e.g. 
Voice Over on OSX), or 'in the cloud'. We just need to get the API right.

Are we ready? Please speak up.

cheers,
David
