TextToSpeech¶

class google.cloud.texttospeech_v1beta1.services.text_to_speech.TextToSpeechAsyncClient(*, credentials: typing.Optional[google.auth.credentials.Credentials] = None, transport: typing.Optional[typing.Union[str, google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport, typing.Callable[[...], google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport]]] = 'grpc_asyncio', client_options: typing.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>)[source]¶

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

Instantiates the text to speech async 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 (Optional[Union[str,TextToSpeechTransport,Callable[..., TextToSpeechTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport to use. If a Callable is given, it will be called with the same set of initialization arguments as used in the TextToSpeechTransport constructor. If set to None, a transport is chosen automatically. NOTE: “rest” transport functionality is currently in a beta state (preview). We welcome your feedback via an issue in this library’s source repository.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “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).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS 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.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
client_info (google.api_core.gapic_v1.client_info.ClientInfo) – The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you’re developing your own client library.

Raises

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

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 (Optional[Union[str,TextToSpeechTransport,Callable[..., TextToSpeechTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the TextToSpeechTransport constructor. If set to None, a transport is chosen automatically. NOTE: “rest” transport functionality is currently in a beta state (preview). We welcome your feedback via an issue in this library’s source repository.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “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).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS 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.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that the api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
client_info (google.api_core.gapic_v1.client_info.ClientInfo) – The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you’re developing your own client library.

Raises

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

__exit__(type, value, traceback)[source]¶: Releases underlying transport’s resources.

Warning

ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

            yield request

    # Handle the response
    for response in stream:

Parameters

requests (Iterator[google.cloud.texttospeech_v1beta1.types.StreamingSynthesizeRequest]) – The request object iterator. Request message for the StreamingSynthesize method. Multiple StreamingSynthesizeRequest messages are sent in one call. The first message must contain a streaming_config that fully specifies the request configuration and must not contain input. All subsequent messages must only have input 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

StreamingSynthesizeResponse is the only message returned to the: client by StreamingSynthesize method. A series of zero or more StreamingSynthesizeResponse messages are streamed back to the client.

Return type

Iterable[google.cloud.texttospeech_v1beta1.types.StreamingSynthesizeResponse]

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

Parameters

request (Union[google.cloud.texttospeech_v1beta1.types.SynthesizeSpeechRequest, dict]) – The request object. The top-level message sent by the client for the SynthesizeSpeech method.
input (google.cloud.texttospeech_v1beta1.types.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 (google.cloud.texttospeech_v1beta1.types.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 (google.cloud.texttospeech_v1beta1.types.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.

Returns

The message returned to the client by the SynthesizeSpeech method.

Return type

google.cloud.texttospeech_v1beta1.types.SynthesizeSpeechResponse

property transport: google.cloud.texttospeech_v1beta1.services.text_to_speech.transports.base.TextToSpeechTransport¶
