I may be misunderstanding you, but to my mind there is an important link 
missing between your items 1+2 and 3: how to make network speech 
services work via *the same API* as the browser's default speech service?

We have pointed out requirements which indicate that we want to allow this:

- FPR7. Web apps should be able to request speech service different from 
default.

- FPR12. Speech services that can be specified by web apps must include 
network speech services.

Now let's assume for the moment we would go for a <tts> element like you 
suggested, which extends HTMLMediaElement. With your items 1-3, how as a 
web app author would I use that <tts> element and tell it to get its 
speech from a TTS engine on the network? In other words, in order for 
the web app to use a networked speech service rather than the built-in 
one, most of the markup / scripts should stay the same, and only the 
reference to the speech service should have to change.

I imagine the browser will have to facilitate this in some way, which 
would mean that we are *not* talking about a protocol just between the 
web app and the speech service... any thoughts?

Cheers,
Marc
