[asterisk-speech-rec] Re: Speech Recognition / 1.4beta3 +LumenVox CRM:00050623

[Scott Stingel]

Hi Adam-

I participated in the early Lumenvox-Asterisk beta program and, after 
the little hassles of upgrading Fedora Core, I was able to get 
everything working. I experienced very good results in simply decoding 
the numbers 0-9 and a few command words - the accuracy was impressive. I 
did have problems with accuracy at first, mostly false decoding, but I 
was able to resolve this by cranking the input audio level down a bit as 
I recall. Maybe in your case playing with the levels will help?

regards
