Before Change

def make_channel(host, port):
    Creates an SSL channel with auth credentials from the environment.
    // In order to make an https call, use an ssl channel with defaults
    ssl_channel = implementations.ssl_channel_credentials(None, None, None)

    creds = credentials.get_credentials().create_scoped([SPEECH_SCOPE])
    // Add a plugin to inject the creds into the header

        "Authorization",
        "Bearer " + creds.get_access_token().access_token)
    auth_plugin = implementations.metadata_call_credentials(
        lambda _, cb: cb([auth_header], None),
