This was well debated in the earlier thread and it is clear that confidence
threshold semantics are tied to the recognizer (not portable). The benefit
of minimizing deaf periods is therefore again recognizer specific and not
portable. This is a well suited use case for custom parameters and I'd
suggest we start with that.

I hope we aren't trying to replicate VoiceXML in the browser. If it is
indeed a must have feature for web developers we'll be receiving requests
for it from them very soon, so it would be easy to discuss and add it in
future.
