// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
* Service Description: Service that implements Google Cloud Text-to-Speech API.
*
* <p>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:
*
* <pre>{@code
* // 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);
* }
* }</pre>
*
* <p>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().
*
* <p>The surface of this class includes several types of Java methods for each of the API's
* methods:
*
* <ol>
* <li>A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available as
* parameters, and not every API method will have a flattened method entry point.
* <li>A "request object" method. This type of method only takes one parameter, a request object,
* which must be constructed before the call. Not every API method will have a request object
* method.
* <li>A "callable" method. This type of method takes no parameters and returns an immutable API
* callable object, which can be used to initiate calls to the service.
* </ol>
*
* <p>See the individual methods for example code.
*
* <p>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.
*
* <p>This class can be customized by passing in a custom instance of TextToSpeechSettings to
* create(). For example:
*
* <p>To customize credentials:
*
* <pre>{@code
* // 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);
* }</pre>
*
* <p>To customize the endpoint:
*
* <pre>{@code
* // 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);
* }</pre>
*
* <p>To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
* the wire:
*
* <pre>{@code
* // 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);
* }</pre>
*
* <p>Please refer to the GitHub repository's samples for more quickstart code snippets.
