TextToSpeech

class google.cloud.texttospeech_v1.services.text_to_speech.TextToSpeechAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.texttospeech_v1.services.text_to_speech.transports.base.TextToSpeechTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/.nox/docs/lib/python3.8/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)[source]

Service that implements Google Cloud Text-to-Speech API.

Instantiates the text to speech client.

Parameters
  • credentials (Optional[google.auth.credentials.Credentials]) – The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.

  • transport (Union[str, TextToSpeechTransport]) – The transport to use. If set to None, a transport is chosen automatically.

  • client_options (ClientOptions) – Custom options for the client. It won’t take effect if a transport instance is provided. (1) The api_endpoint property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: “always” (always use the default mTLS endpoint), “never” (always use the default regular endpoint) and “auto” (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the api_endpoint property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is “false” or not set, no client certificate will be used.

Raises

google.auth.exceptions.MutualTlsChannelError – If mutual TLS transport creation failed for any reason.
