I have been working on designs for two different projects, where both
of them would need to use the IBM Watson streaming ASR service.

Would it be possible to write out the audio frames as they get
recorded? Watson supports 16 bit signed little endian audio, IIRC, but
there are a few other raw formats available.

That's the main problem I was discussing at AstriDevCon. There's no way
currently to stream the frames to a service.

At the moment I'm saving to a file and then sending that file once
recording has finished.

The UnicastRTP channel driver allows you to send RTP to a specific target address with media. Combined with Chanspy (or Snoop channels in ARI) you can duplicate audio from a channel and send it off to where you want.
