AGI not returning confidence parameter #21

Closed dvarella closed 8 years ago

dvarella commented 8 years ago

Dear Zaf,

The speech-recog.agi was working perfectly for months, but since some weeks ago I´m checking that It is not returning the "confidence" parameter anymore as you can see by Asterisk AGI debug attached file. And I was using that parameter to check how "confident" the recognition engine feels about the result. Is there any trouble with this engine ? How can I start receive this parameter again ?

PS: Since then I realized that recognition has a certain drop in quality. Where, for example, my name was recognized in my tests often as "Daniels," "Daniel 1", "Danieles", and my correct name is 'Daniel'. Earlier recognition is very in tune.

Thank you for the report, I noticed it a few days ago. The format of the JSON data that the API returns has changed a bit lately. I will push a fix soon.

Fix pushed, feel free to test and report.
