where is Speech-to-Text v1 Stream-recognize way with grpc?

[ConcreteW]

The doc says :

The Speech-to-Text v1 is officially released and is generally available from the https://speech.googleapis.com/v1/speech endpoint. The Client Libraries are released as Alpha and will likely be changed in backward-incompatible ways. The client libraries are currently not recommended for production use.

but the demo only show client way at com.google.cloud.speech.v1p1beta1 package.

so I want know where is the demo of speech-text with the stable gRPC way ?
where is the old version code ?
or now the stream speech is Alpha status ,only stand for this demo now?

thanks for answer .

Hi thanks for looking in.

The samples as is should work for v1 if you switch the imports.

We have a PR going on right now to fix this issue: #1212.

Let me know if that helps. :)
