Methods

TextToSpeechAsyncClient

TextToSpeechAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from'/workspace/python-texttospeech/.nox/docfx/lib/python3.9/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>)

Instantiate 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.

list_voices

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

Returns a list of Voice supported for synthesis.

Parameters
Name Description
request ListVoicesRequest

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. E.g. when specifying "en-NZ", you will get supported "en-NZ" voices; when specifying "no", you will get supported "no-*" (Norwegian) and "nb-*" (Norwegian Bokmal) voices; specifying "zh" will also get supported "cmn-*" voices; specifying "zh-hk" will also get supported "yue-hk" voices. This corresponds to the language_code field on the request instance; if request is provided, this should not be set.
retry google.api_core.retry.Retry

Designation of what errors, if any, should be retried.
timeout float

The timeout for this request.
metadata Sequence[Tuple[str, str]]
