I suspect this will be very similar in implementation to switch_core_asr, so we could either reuse that interface, or implement a new Speaker Identification and Verification (SIV) interface.  Hop on #freeswitch-dev to talk this over and figure out the best approach.

If you implement a new interface, you probably need at least the following functions:

switch_core_siv_open
switch_core_siv_close
switch_core_siv_pause
switch_core_siv_resume
switch_core_siv_feed
switch_core_siv_get_results
switch_core_siv_start_input_timers

And then some new functions in switch_ivr_async.c:

switch_ivr_detect_speaker
switch_ivr_pause_detect_speaker
switch_ivr_resume_detect_speaker
switch_ivr_stop_detect_speaker
switch_ivr_detect_speaker_start_input_timers

And a new application in mod_dptools.c

detect_speaker

That's it ! I was talking about speaker identification by comparing the
speaker's voiceprint with
pre-trained voiceprint saved in a voiceprint repository. Sure, I've
heard about Nuance is planning to acquire
Loquendo, another speech processing shark ;)

I was thinking about creating a new abstract interface called e.g.
switch_sid_interface (SID = speaker identification) which
could be binded to e.g. a proprietary interface module or (the better
solution) to mod_unimrcp since MRCPv2 protocol supports
speaker identification/verification. Using this sid interface w/
mod_unimrcp FreeSWITCH would be able to use MRCP
servers for speaker identification/verification. Currently Nuance and
Loquendo has few MRCP servers supporting this service and
of course our company is planning to deploy a MRCPv2 server soon.
Example application is e.g. instead of looking for your customer
ID or telling your personal ID data to the operator who needs to have
your identity confirmed before he/she tells you some confidental info,
the company (whether call center or whatever) would just use speaker
identification service via MRCPv2 and from 3 to 5 seconds of voice
he/she will know, whether the person is really the one he/she is
claiming he/she is or not.

What do you think about it ??

Have a nice day ;)

Sincerely, Viktor Jamrich.
