[Asterisk-Users] speech recognition V 2.0

[Race Vanderdecken]

Greetings David,

PerlBox would not be usable for the level of service that is needed by
Asterisk to be viable Speech.

PerlBox is a vocabulary based recognizer, or I as I call it a "grunter",
where you grunt something and it then does something cute.

Grunters depend on you creating a "vocabulary" list that is different
enough in the syllables so that it can tell cookie from kooky.

So long as each grunt is different you can get a response from it.

But a grunter can't do "computer, call my mother-in-law in France using
the PSTN connection". It can do "Mom". If you talk to a computer the way
you talk to a dog you don't get much more then sit, stay and down.

The problem and the reason such Reco has never gained support is like
all Voice/Speech Activated Dialing engines is that you have to remember
all the vocabulary to use it.

If you want to call "Robert" you can't say "Bob".

Grammar based recognition is the only solution. I know because I have
watched several companies' which demanded that they can do it with
grunter, which go out of business because the "Stupid Customers" won't
learn how to use the system correctly. 

Maybe we should refer to the grunter engines as the Neanderthal engines.
Not so much an evolutionary step so much as a evolutionary sidetrack
experiment that went down a dead end. Grammar reco is not descendent
from grunters; it starts further up the tree and is a distinct
evolutionary line. 

As to PerlBox, I give kudos for their efforts for watch they have
accomplished and their efforts are to be applauded for its segment. But
it will not be able to progress into a useful and widely accepted
Asterisk add-on.

Sphinx and Festival are good projects. The last I worked with sphinx I
was told that it would need modifications to make it more grammar aware,
but that was 2 years ago and things may have improved. If not then
Sphinx people please let me know when you will add grammars natively or
refer me a grammar based engine.
