Methods

TextToSpeechAsyncClient

TextToSpeechAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport] = 'grpc_asyncio', client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the text to speech client.

Parameters

Name	Description
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.

Exceptions

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

get_mtls_endpoint_and_cert_source(
    client_options: Optional[google.api_core.client_options.ClientOptions] = None,
)

Return the API endpoint and client cert source for mutual TLS.

The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.

The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variabel is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

list_voices

list_voices(request: Optional[Union[google.cloud.texttospeech_v1beta1.types.cloud_tts.ListVoicesRequest, dict]] = None, *, language_code: Optional[str] = None, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Returns a list of Voice supported for synthesis.

from google.cloud import texttospeech_v1beta1

async def sample_list_voices():
    # Create a client
    client = texttospeech_v1beta1.TextToSpeechAsyncClient()

    # Initialize request argument(s)
    request = texttospeech_v1beta1.ListVoicesRequest(
    )

    # Make the request
    response = await client.list_voices(request=request)

    # Handle the response
    print(response)

Parameters

Name	Description
request	`Union[google.cloud.texttospeech_v1beta1.types.ListVoicesRequest, dict]` The request object. The top-level message sent by the client for the `ListVoices` method.
language_code	`str` Optional. Recommended. `BCP-47 <https://www.rfc-editor.org/rfc/bcp/bcp47.txt>`__ language tag. If not specified, the API will return all supported voices. If specified, the ListVoices call will only return voices that can be used to synthesize this language_code. For example, if you specify `"en-NZ"`, all `"en-NZ"` voices will be returned. If you specify `"no"`, both `"no-\"` (Norwegian) and `"nb-\"` (Norwegian Bokmal) voices will be returned. This corresponds to the `language_code` field on the `request` instance; if `request` is provided, this should not be set.
