[asterisk-users] Speech recognition in asterisk using google voice API

[Michelle Dupuis]

Wow - nice!  A few quick questions:

1.  How long can the recording be for translation?
2.  Any limitation on how much text the return (transcribed) variable can hold?
3.  Any commercial / terms of use limitations?

Note to self: "Never release anything asterisk related without testing
on RHEL/Centos 5"

Thank you for reporting this. I have replaced sox with flac and it seems
to work now on older platforms too (tested on Centos 5 with asterisk 1.4).
You can get the updated code here:

Works beautifully. Amazing job Lefteris. Thanks.

The best result I got in probability was 0.9725632 by saying, "hello". I think there is some non-phonetic logic built-in as well. I tried, "1, 2" and I got "0.86534226" in accuracy. While I tried "1, 2, 3, 4, 5" I got, "0.97256315". Probably Google sees the pattern?!

What are some of the other tricks (if any) or consideration that one should make while creating a strong speech recognition enabled IVR?

Best,
