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

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (TextToSpeechClient textToSpeechClient = TextToSpeechClient.create()) {
   String languageCode = "languageCode-2092349083";
   ListVoicesResponse response = textToSpeechClient.listVoices(languageCode);
 }

Note: close() needs to be called on the TextToSpeechClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method	Description	Method Variants
ListVoices	Returns a list of Voice supported for synthesis.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listVoices(ListVoicesRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listVoices(String languageCode) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listVoicesCallable()
SynthesizeSpeech	Synthesizes speech synchronously: receive results after all text input has been processed.	Request object method variants only take one parameter, a request object, which must be constructed before the call. synthesizeSpeech(SynthesizeSpeechRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. synthesizeSpeech(SynthesisInput input, VoiceSelectionParams voice, AudioConfig audioConfig) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. synthesizeSpeechCallable()
StreamingSynthesize	Performs bidirectional streaming speech synthesis: receive audio while sending text.	Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. streamingSynthesizeCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of TextToSpeechSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TextToSpeechSettings textToSpeechSettings =
     TextToSpeechSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 TextToSpeechClient textToSpeechClient = TextToSpeechClient.create(textToSpeechSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TextToSpeechSettings textToSpeechSettings =
     TextToSpeechSettings.newBuilder().setEndpoint(myEndpoint).build();
 TextToSpeechClient textToSpeechClient = TextToSpeechClient.create(textToSpeechSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TextToSpeechSettings textToSpeechSettings = TextToSpeechSettings.newHttpJsonBuilder().build();
 TextToSpeechClient textToSpeechClient = TextToSpeechClient.create(textToSpeechSettings);

Constructor Detail
- TextToSpeechClient
```
protected TextToSpeechClient(TextToSpeechSettings settings)
                      throws IOException
```
  Constructs an instance of TextToSpeechClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.
  
  Throws:
  
  IOException
- TextToSpeechClient
