speech-api returning empty results no matter what

[E. Schmidbauer]

Hello,
I'm trying to test out google's speech API using just simple curl command.
No matter what I try (different files/sample rates/etc...) google
returns an empty JSON result.

Here is my call:

curl -X POST --data-binary @audio/message.flac --header 'Content-Type:
audio/x-flac; rate=16000;'
'https://www.google.com/speech-api/v2/recognize?output=json&lang=en-US&key=___API_KEY___&maxresults=9&pfilter=0'


Any ideas?

Thanks,
E

That API is only for Chrome and Chromium development/testing.

Do you have your own API KEY? If you got it try with this call:

curl -X POST \

--data-binary @'PATH_TO_YOUR_FILE' \

--header 'Content-Type: audio/l16; rate=16000;' \

'https://www.google.com/speech-api/v2/recognize?output=json&lang=en-US&client=chromium&maxresults=1&key=YOUR_API_KEY'

Hi Igor,
I tried that as you specified. I know my API key is valid because if I
change it (to something invalid) I get an error

curl -X POST --data-binary @audio/message.flac --header 'Content-Type:
audio/x-flac; rate=16000;'

'https://www.google.com/speech-api/v2/recognize?output=json&lang=en-US&client=chromium&maxresults=1&key=___KEY____'


Only returns:

{"result":[]}

If you tried with my example, your audio data should be in "wav" format. Can you try it with a wav audio recording? 

[E. Schmidbauer]

Hi Igor,
I tried with your example too:

curl -X POST --data-binary @'hello (16bit PCM).wav' --header
'Content-Type: audio/l16; rate=16000;'
'https://www.google.com/speech-api/v2/recognize?output=json&lang=en-US&client=chromium&maxresults=1&key=__KEY__'


Still only returns:

{"result":[]}

Thanks

This mailing list is not an appropriate place to discuss how to break Google's terms of service.

Did you find any solution? I am stuck in a very similar situation. Not matter what I send, wav files, mp3, RAW files or linear16, I always get empty response.
