Methods

TextToSpeechAsyncClient

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/python-texttospeech/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

Instantiate the text to speech client.

Parameters
NameDescription
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 environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint, this is the default value for the environment variable) and "auto" (auto switch to the default mTLS endpoint if client SSL credentials is present). However, the api_endpoint property takes precedence if provided. (2) The client_cert_source property is used to provide client SSL credentials for mutual TLS transport. If not provided, the default SSL credentials will be used if present.

Exceptions
TypeDescription
google.auth.exceptions.MutualTlsChannelErrorIf mutual TLS transport creation failed for any reason.

from_service_account_file

from_service_account_file(filename: str, *args, **kwargs)

Creates an instance of this client using the provided credentials file.

Parameter
NameDescription
filename str

The path to the service account private key json file.

Returns
TypeDescription
{@api.name}The constructed client.

from_service_account_json

from_service_account_json(filename: str, *args, **kwargs)

Creates an instance of this client using the provided credentials file.

Parameter
NameDescription
filename str

The path to the service account private key json file.

Returns
TypeDescription
{@api.name}The constructed client.

get_transport_class

get_transport_class()

Return an appropriate transport class.

list_voices

list_voices(request: Optional[google.cloud.texttospeech_v1.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
NameDescription
request .cloud_tts.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 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-*" 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-*" 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]]

Strings which should be sent along with the request as metadata.

Returns
TypeDescription
.cloud_tts.ListVoicesResponseThe message returned to the client by the ListVoices method.

synthesize_speech

synthesize_speech(request: Optional[google.cloud.texttospeech_v1.types.cloud_tts.SynthesizeSpeechRequest] = None, *, input: Optional[google.cloud.texttospeech_v1.types.cloud_tts.SynthesisInput] = None, voice: Optional[google.cloud.texttospeech_v1.types.cloud_tts.VoiceSelectionParams] = None, audio_config: Optional[google.cloud.texttospeech_v1.types.cloud_tts.AudioConfig] = None, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Synthesizes speech synchronously: receive results after all text input has been processed.

Parameters

audio_config .cloud_tts.AudioConfig

Required. The configuration of the synthesized audio. This corresponds to the audio_config 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]]
