Cannot Recognize Speech Invalid WAV header in file, data block was not found

[twizzyyanki]

I have a wav file and I am trying to use it to text azure speech to text using this url - https://azure.microsoft.com/en-us/services/cognitive-services/speech-to-text/#features. I am getting Cannot Recognize Speech Invalid WAV header in file, data block was not found error. I am not sure what is wrong and why I am getting this error. The wav file looks totally fine to me. This is the file I am using to test - http://talonsoftwares.com/upload/2422332.wav

Hi, thanks for reporting the issue - the problem occurs because of a WAV header size limit in the JavaScript SDK. There is now a pull request to raise this limit: microsoft/cognitive-services-speech-sdk-js#328

For comparison, https://github.com/Azure-Samples/cognitive-services-speech-sdk/blob/master/sampledata/audiofiles/aboutSpeechSdk.wav where the header has no metadata:

and your 2422332.wav which contains an INFO chunk in the header which happens to go over the limit:

Hello,
I faced the same issue and I solved it simply by converting my audio sample rate from 48kHz to 16kHz.
It worked well after that.

solved it by converting to 16kHz too, weird that it doesn't work out of the box, but it's MS right haha
