<p class="MsoNormal">I certainly don't mind if a better-designed system comes along and obviates my AudioSocket implementation. I built it because I needed it. However, bidirectional audio flow is critical for me (speech synthesis, external interfacing, real-time
processed audio, processed injections, etc). While I would actually prefer a system which was a bit beefier than my own (simple protocol aside, there's a good deal of range between my protocol and MRCP), my meagre C skills (and patience) don't allow me to
venture forth into those difficult waters.<u></u><u></u></p>

<p class="MsoNormal">I was on vacation when this thread happened but I'm also working on this now. The implementation uses the existing ARI channel and bridge recording endpoints ands add the ability to specify a URI in the form of (udp|tcp|tls)://hostname:port
to stream the media. This makes use of the existing chan_bridge_media driver and only requires a scheme handler similar to Seán's res_audiosocket. This implementation is more targeted to real-time speech recognition/transcription/captioning and is therefore
one way (outbound). A future enhancement is planned that would send each channel in a bridge as a separate audio channel in a multi-channel container.<u></u><u></u></p>

This is very different from what we did. You need dialplan to use it. In our case we don't need any dialplan to use it, it's more ARI approach.<br>
