[MV] Voice Recognition Tech Question

[Chuck Rogers]

Dave:

Large corporations use a limited vocabulary speech recognition  
system. Typically, these systems can recognize only about 1000 words  
(or less). The way the usually work is that the computer is listening  
for a word it recognizes, and then executes the appropriate action  
based on the response.

For instance, if you call to get flight information it might ask you  
if the flight is for today or tomorrow. It may even allow you to say  
the day of the week. If you say "I would like flight information for  
tomorrow" it hears "tomorrow." But if you say "I'd like flight  
information for two weeks from Thursday" or "the second Wednesday in  
April" it would not know how to handle the request.

They don't need training because of the limited vocabulary. The fewer  
words that need to be recognized, the fewer that can sound alike,  
also, context is not an issue. All this makes it easy to be  
recognized. In a way, they are not that much different from the  
Speakable Items developed by Apple.

Make sense?
