[VoIP] Speech recognition demo

[Richard Walsh]

I suspect that directory assistance on CNET could also be implemented using this voice recognition software.  Something like CNET 1-411, and you would say a last name and it would do a look up and talk back the number.  Probably complete the call when asked by a prompt ( ....If you would like to call this number now, say "YES" ...).
  Everyone could indicate a main listed directory number for their location)

A couple of points.
It wants you to say the "1" If you do not, it will fail
Also it is REALLY impatient. If you don't speak quickly, it will also fail

Doubtful if anyone would pay real money on a per call basis.
A low cost one time fee might work

Just my 2 pence
