Has anyone found a way to either A) Activate the mic control from javascript or B) Enable continuous recording once the user has initiated recording? I understand the security implications of A. However, B would be an acceptable alternative since the user initiates it. I'm imaging a vocal interface that requires minimal user keyboard interaction. I found an attribute called "continue", but it doesn't seem to do anything special when added to the input element.
