It’s a straightforward two-step process.
One: make sure you have version 1.0.0 or later of google-cloud-speech (use
!pip freeze | grep google-cloud-speech)
Two: Instead of importing the client libraries like
from google.cloud import speech from google.cloud.speech import enums, types
import them like
from google.cloud import speech_v1p1beta1 as speech, storage from google.cloud.speech_v1p1beta1 import enums, types
The beta features should now be available for you to use.
