Voice recognition for asterisk based on Google speech API is already available[1],
the problem with this service is that it's limited to 20-30 seconds of speech data,
which isn't suitable for transcripting voicemails.
If you are able to find a reliable way of chopping speech samples in segments no bigger
than 20 seconds based on silence detection, so words wont be cut in half, you might come
up with something very similar to Google Voice transcription service.
But I would recommend against using this into production since google haven't yet
defined the terms of service for speech recognition, and its more or less a hack for
now.
