Dear,

We have a requirement to limit per user usage of speech streaming recognition.
We want to limit by user identity "quotaUser" param as specified here:

So far I cannot find out how to do that from Cloud Speech API doc.
Could you please help me providing a sample code in python?
if it even better if you use speech_streaming.py example code.
