// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
 * 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:
 *
 * 
 * 
 * try (TextToSpeechClient textToSpeechClient = TextToSpeechClient.create()) {
 *   String languageCode = "";
 *   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().
 *
 * 
The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * 

 *    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.
 *   
 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.
 *   
 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.
 * 
 *
 * 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:
 *
 * 
 * 
 * TextToSpeechSettings textToSpeechSettings =
 *     TextToSpeechSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * TextToSpeechClient textToSpeechClient =
 *     TextToSpeechClient.create(textToSpeechSettings);
 * 
 * 
 *
 * To customize the endpoint:
 *
 *  * 
 * TextToSpeechSettings textToSpeechSettings =
 *     TextToSpeechSettings.newBuilder().setEndpoint(myEndpoint).build();
 * TextToSpeechClient textToSpeechClient =
 *     TextToSpeechClient.create(textToSpeechSettings);
 * 
 *
