Cloud Text-to-Speech V1 Client - Class TextToSpeechClient (1.10.0)

Reference documentation and code samples for the Cloud Text-to-Speech V1 Client class TextToSpeechClient.

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.

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 parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Namespace

Google \ Cloud \ TextToSpeech \ V1 \ Client

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

listVoices

Returns a list of Voice supported for synthesis.

The async variant is Google\Cloud\TextToSpeech\V1\Client\TextToSpeechClient::listVoicesAsync() .

Parameters

/**
 * @param string $voiceLanguageCode        The language (and potentially also the region) of the voice

 *                                         language tag, e.g. "en-US". This should not include a script tag (e.g. use
 *                                         "cmn-cn" rather than "cmn-Hant-cn"), because the script will be inferred
 *                                         from the input provided in the SynthesisInput.  The TTS service
 *                                         will use this parameter to help choose an appropriate voice.  Note that
 *                                         the TTS service may choose a voice with a slightly different language code
 *                                         than the one selected; it may substitute a different region
 *                                         (e.g. using en-US rather than en-CA if there isn't a Canadian voice
 *                                         available), or even a different language, e.g. using "nb" (Norwegian
 *                                         Bokmal) instead of "no" (Norwegian)".
 * @param int    $audioConfigAudioEncoding The format of the audio byte stream.
