[Freeswitch-dev] Speaker Identification implementation

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 ;)
