If Nuance has a public web based speech service and it exposes
the API for it, browsers
could use it as a default speech engine when the device is online.
Or browsers could use some other engine.

I'm not sure I understand this.

My assumption has been that we're designing a framework or API
for the Web. And "the Web" includes commercial and academic entities,
but also individual web developers and users.

Well, v1 would certainly give some of the target audience something
to try out.

My assumption for v1 has been that it would be used especially by
those web developers who want to try out all the latest
web technologies, even if that would limit which
browsers they could support (since it takes time before an
API is implemented by all the UAs).
Also, similarly some companies, like Google and Facebook
tend to try new technologies rather soon, even sooner than the APIs
have stabilized.
