[Asterisk-Users] Speech Recognition

The limited domain reference is obsolete, Telstra have a 2 million
record database (yeh I know it's a lot smaller when you dice it
phonetically but it's still big enough).

Hi Dean,

You seem to have had your head up the supplier's arse for a number of 
years. :-)

I last tried a Nuance demo system in about 2002, and found it useless. 
Speechworks (now scansoft) was rather better, but still useless for 
English. I'm British. Trying the British system gave poor results. 
Trying the US system seldom gave the right answer. Speechwork's Chinese 
(Cantonese and Mandarin) was pretty good, though.

I've never seen Nuance offer free form speech to text, and I can't see 
Angel or Nuance's sites claiming that. They offer free form IVR input 
within a limited domain, which is something quite different - the set of

possible outcomes is so much smaller.

The best free form speech to text systems still require considerable 
user specific training to achieve reasonable accuracy. Some people 
eventually get good results, while others never do. Maybe some people 
just talk in a much more consistent way.

Regards,
Steve
