I JUST NOTICED THAT THIS ISSUE IS DUPLICAT,
THE OTHER ISSUE IS HERE: #822

I have a problem using pywit which is the python library for WitAi

For couple of days I've been using pywit in my app, which has 5K~ uses per day.
Until today everything worked perfect.

This is my code:
Wit('TOKEN').speech(open('file.wav', 'rb').read(), headers={'Content-Type': 'audio/wav'})['_text']
For a couple of hours now, I sometimes get this error:

Traceback (most recent call last):
File "", line 1, in
File "C:\Develop\XXX\wit_ai_client.py", line 14, in recognize
return Wit(XXX).speech(wav_content, headers={'Content-Type': 'audio/wav'})['_text']
File "C:\Python35\lib\site-packages\wit\wit.py", line 102, in speech
data=audio_file, headers=headers)
File "C:\Python35\lib\site-packages\wit\wit.py", line 41, in req
' (' + rsp.reason + ')')
wit.wit.WitError: Wit responded with status: 400 (Bad Request)

Sometimes the translation return just right, but sometimes pywit throws this error
