Hello Andrew
I wanted to get more information on this integrated chipset. I believe there are two forms of speech technology
TTS == Text to Speech
STT == Speech to Text
Now what is TI and speechworks doing for their upcomming integrated chipset? The most I have seen are comand and control functions

(I don't work at SpeechWorks but I know lots of people that do.)
I am also led to believe that handset vendors or network operators have
plans in place to implement this as part of future systems.
If you are interested in more info - get in touch offline.
Cheers

If you can persuade them to eat the bear after use, you have a
delicious one-time authorisation scheme :)

A lot of biometric performance depends heavily on environmental
factors, change the environment slightly (different lighting, wearing
glasses, sweaty hands etc) and you'll have plenty of problems. Given
the mobile nature of the device accuracy would be nightmarish (next to
a busy street, crowded room with people talking, music etc).
As far as analysis is concerned you should certainly be able to do the
processing on the network side (unless you want to authenticate
directly to the handset). Lastly the spoken phrase needs to change with
every session to avoid replays.
Yes, biometrics sound sexy, in reality it's far from trivial to do
effectively. Again, compare to implementing a four digit PIN...
Has anyone here looked at or implemented NTT Lab's SAS (Simple and
Secure Password Authentication System) protocol?
