Class TextToSpeechClient (2.31.0)

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

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

ListVoices(std::string const &, Options)

Returns a list of Voice supported for synthesis.

Parameters
Name Description
language_code std::string const &

Optional. Recommended. BCP-47 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.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StatusOr< google::cloud::texttospeech::v1::ListVoicesResponse >

the result of the RPC. The response message type (google.cloud.texttospeech.v1.ListVoicesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

ListVoices(google::cloud::texttospeech::v1::ListVoicesRequest const &, Options)

Returns a list of Voice supported for synthesis.

Parameters
Name Description
request google::cloud::texttospeech::v1::ListVoicesRequest const &

Unary RPCs, such as the one wrapped by this function, receive a single request proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.texttospeech.v1.ListVoicesRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StatusOr< google::cloud::texttospeech::v1::ListVoicesResponse >

the result of the RPC. The response message type (google.cloud.texttospeech.v1.ListVoicesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

SynthesizeSpeech(google::cloud::texttospeech::v1::SynthesisInput const &, google::cloud::texttospeech::v1::VoiceSelectionParams const &, google::cloud::texttospeech::v1::AudioConfig const &, Options)

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

Parameters
Name Description
input google::cloud::texttospeech::v1::SynthesisInput const &

Required. The Synthesizer requires either plain text or SSML as input.

voice google::cloud::texttospeech::v1::VoiceSelectionParams const &

Required. The desired voice of the synthesized audio.

audio_config google::cloud::texttospeech::v1::AudioConfig const &

Required. The configuration of the synthesized audio.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StatusOr< google::cloud::texttospeech::v1::SynthesizeSpeechResponse >

the result of the RPC. The response message type (google.cloud.texttospeech.v1.SynthesizeSpeechResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

SynthesizeSpeech(google::cloud::texttospeech::v1::SynthesizeSpeechRequest const &, Options)

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

Parameters
Name Description
request google::cloud::texttospeech::v1::SynthesizeSpeechRequest const &

Unary RPCs, such as the one wrapped by this function, receive a single request proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.texttospeech.v1.SynthesizeSpeechRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StatusOr< google::cloud::texttospeech::v1::SynthesizeSpeechResponse >

the result of the RPC. The response message type (google.cloud.texttospeech.v1.SynthesizeSpeechResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the StatusOr contains the error details.

AsyncStreamingSynthesize(Options)

Performs bidirectional streaming speech synthesis: receive audio while sending text.

Parameter
Name Description
opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
std::unique_ptr<::google::cloud::AsyncStreamingReadWriteRpc< google::cloud::texttospeech::v1::StreamingSynthesizeRequest, google::cloud::texttospeech::v1::StreamingSynthesizeResponse > >

An object representing the bidirectional streaming RPC. Applications can send multiple request messages and receive multiple response messages through this API. Bidirectional streaming RPCs can impose restrictions on the sequence of request and response messages. Please consult the service documentation for details. The request message type (google.cloud.texttospeech.v1.StreamingSynthesizeRequest) and response messages (google.cloud.texttospeech.v1.StreamingSynthesizeResponse) are mapped to C++ classes using the Protobuf mapping rules.

ListOperations(std::string const &, std::string const &, Options)

Lists operations that match the specified filter in the request.

If the server doesn't support this method, it returns UNIMPLEMENTED.

NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users/*/operations. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

Parameters
Name Description
name std::string const &

The name of the operation's parent resource.

filter std::string const &

The standard list filter.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StreamRange< google::longrunning::Operation >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.longrunning.Operation, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListOperations(google::longrunning::ListOperationsRequest, Options)
