This doesn't follow the convention for audio constraints.
Btw, does this need to be available in Chrome?  If so, talk to hta@ about how to
do that.

By convention do you mean the "goog" prefix? Because I thought we were moving
away from that.
At this point we are only targeting native and I am familiar adding media
constraints to Chrome, but I will contact hta if/when we decide to do so.
Thanks! :)

This should be intelligibilityEnhancer

You are totally right. Changed.
