Methods

TextToSpeechClient

TextToSpeechClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport] = None, 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
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 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
Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If 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
Name	Description
`filename`	`str` The path to the service account private key json file.

Returns
Type	Description
`{@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
Name	Description
`filename`	`str` The path to the service account private key json file.

Returns
Type	Description
`{@api.name}`	The constructed client.

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`	`.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
Type	Description
`.cloud_tts.ListVoicesResponse`	The message returned to the client by the `ListVoices` method.

synthesize_speech

synthesize_speech(request: Optional[google.cloud.texttospeech_v1beta1.types.cloud_tts.SynthesizeSpeechRequest] = None, *, input: Optional[google.cloud.texttospeech_v1beta1.types.cloud_tts.SynthesisInput] = None, voice: Optional[google.cloud.texttospeech_v1beta1.types.cloud_tts.VoiceSelectionParams] = None, audio_config: Optional[google.cloud.texttospeech_v1beta1.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
Name	Description
`request`	`.cloud_tts.SynthesizeSpeechRequest` The request object. The top-level message sent by the client for the `SynthesizeSpeech` method.
`input`	`.cloud_tts.SynthesisInput` Required. The Synthesizer requires either plain text or SSML as input. This corresponds to the `input` field on the `request` instance; if `request` is provided, this should not be set.
`voice`	`.cloud_tts.VoiceSelectionParams` Required. The desired voice of the synthesized audio. This corresponds to the `voice` field on the `request` instance; if `request` is provided, this should not be set.
`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]]` Strings which should be sent along with the request as metadata.
