[Freeswitch-users] Speech Recognition recording to URL

[David Horton]

Also FWIW I have open sourced a freeswitch module that integrates with google transcription:

It requires building a version of freeswitch that links with GRPC libs

Probably you are already aware of this, but just in case, there is in fact a ModUniMRCP plugin for GSR:

It works well, but it is non-free.

Hi,
out of curiosity, I'm trying to see if I can use application record + mod_httapi (https://freeswitch.org/confluence/display/FREESWITCH/mod_httapi <https://freeswitch.org/confluence/display/FREESWITCH/mod_httapi>)
to connect with Google Speech Recognition service (via a proxy app that will handle HTTP to gRCP convertion).
Just as a test, I'm trying to see if using an inbound event socket I can inject a DETECTED_SPEECH event in a channel.
I tried something like this and got an +OK from FS:

T 192.168.88.78:60380 <http://192.168.88.78:60380/> -> 192.168.88.74:8021 <http://192.168.88.74:8021/> [AP]
sendevent DETECTED_SPEECH
Unique-ID: a03486b8-781d-430a-ab26-5815485401a8
Call-UUID: a03486b8-781d-430a-ab26-5815485401a8
call_uuid: a03486b8-781d-430a-ab26-5815485401a8

Channel-UUID: a03486b8-781d-430a-ab26-5815485401a8
Speech-Type: begin-speaking

T 192.168.88.74:8021 <http://192.168.88.74:8021/> -> 192.168.88.78:60380 <http://192.168.88.78:60380/> [AP]
Content-Type: command/reply
Reply-Text: +OK 64bdd4aa-9476-4db8-b56c-36a62f6a2238

but nothing got notified to the channel (and no logs about it from FS running in debug level)

Would this be actually possible?
