[asterisk-dev] Speech Recognition

[John Lange]

A "sort-of" on topic question here. Are there different speech
recognition engines depending on the application?

It occurs to me that speech recognition might be much more accurate if
it wasn't required to do its analysis in real time. So for example,
transcribing voicemail to text could be done off-line after the caller
hangs up.

Since the engine has more time it could potentially do a better job
processing the data stream. It could make several passes filtering out
background noise etc. etc. but all of the speech engines I've come
across only focus on "real-time" recognition.

Anyone know a bit more about this topic?
