After a quick read I, in general, like the proposal.

Few comments though.

- What should happen if for example
   What happens to the events which are fired during that time?
   Or should recognition stop?

- What exactly are grammars builtin:dictation and builtin:search?
   Especially the latter one is not at all clear to me

- When does recognitionState change? Before which events?

- It is not quite clear how SGRS works with <input type="speech">

- I believe there is no need for
   DOMImplementation.hasFeature("SpeechInput", "1.0")

And I think we really need to define something for TTS.
Not every web developers have servers for text -> <audio>.
