[Freeswitch-users] Copy incoming audio from participants for ASR

[R G]

Hello everyone,

i have a technical question about freeswitch and would like to know if 
my idea is technically possible.

I've got a project at the university and my goal is to improve automatic 
speech recognition for bigbluebutton.

In the summer semester a group of students of my university made a 
subtitling plugin[1] for bigbluebutton. This plugin adds a participant 
into the meeting and grabs his audiostream to send it to the kaldi ASR 
Software. When more than one person speaks at a time the detection 
decreases.

My idea is to copy the incoming freeswitch audiostreams from every 
participant and send them directly as a copy to the ASR (kaldi can 
handle multiple audiostreams at once).

In the Confluence-Wiki i searched for something in this direction but 
only found things like Dialplan to ring multiple telephones at once.

I hope my idea is formulated understandably.


Kind regards,

Robert
