Expose stream cancellation in speech streaming generator

See original GitHub issue

Originally from python-docs-samples#963, filed by @datspike

How do you stop recognition correctly in the new client?

With the GRPC client, you can do

recognize_stream = service.StreamingRecognize(
    requests, self.DEADLINE_SECS)
...
recognize_stream.cancel()

But this client lib only exposes the streaming_recognize call as a generator of alternatives. It would be useful to be able to cancel the stream from another thread, eg in case you need to close the stream before a response is returned.

@Tadly Can you please open a new issue? This one is a) long-closed, and b) only tangentially related to the problem you are experiencing.

Pardon my intrusion but I’m kind of stuck on this.

As far as I can tell, streaming_recognize straight up blocks if the backend can’t resolve a anything from the given stream (e.g. mic is muted, no one is speaking etc.).

As I’m trying to get this implemented in an asyncio environment this is kind of bad. Even if I’d add threading (which I’d like to prevent) I’d still have the issue of it blocking -> no _Rendezvous instance.

Am I missing something obvious here?
