voice recognition specialist needed

[ik]

David,

Again, what exactly are your requirements?

Do you require to identify a word ?
Do you require to understand the whole sentence ?
Do you need to know that "David" is "David" and not someone else ?

The three types of scenarios here are three different types of systems,
with three different types of products to use, and the voice signature has
it's own companies in that field.

To recognize a person, there are few companies in the world that does it,
and it costs tons of money, and depends on so many levels.
The thing is, that telephony (e.g. land line and sip trunk to land line)
always works in 8KHz (usually g711 and g729 in codecs), and that makes
things not very good to the subject, however codecs such as OPUS works in
Full HD and provides a lot more data to use, but not supported in many
places.

To understand a sentence, there are voice recognition services, such as
Nuance's, that afaik, does not capable in supporting Hebrew at all.

Last, you have keyword spotting, for example the way Pago works. You say a
name of a city, and it try to figure out pattern that is close enough to
that city.
It cannot understand all the words, but specific words that is was
programmed to find out.
For example the Israeli Police uses it for getting your ID number when you
want to know about speeding tickets in the IVR, and it doesn't work in all
cases.

I do not know of any open source solution for any of this type of solutions.
AFAIK, Asterisk does not support it by default, but requires plugins
depends on the system, or to send recordings to external system.
Freeswitch (another open source PBX) does support some of the protocols,
but not all, again, depends on what the exact solution is.
There is also YATE (another open source PBX), that I have never used, so I
cannot say,

It's too hard to answer more then that, without you explaining your actual
needs.

Ido
