Class v1beta1.SpeechTranslationServiceClient (2.4.0)

Provides translation from/to media types. v1beta1

Package

@google-cloud/media-translation

Constructors

(constructor)(opts)

constructor(opts?: ClientOptions);

Construct an instance of SpeechTranslationServiceClient.

Parameter
NameDescription
opts ClientOptions

Properties

apiEndpoint

static get apiEndpoint(): string;

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

auth

auth: gax.GoogleAuth;

descriptors

descriptors: Descriptors;

innerApiCalls

innerApiCalls: {
        [name: string]: Function;
    };

port

static get port(): number;

The port for this API service.

scopes

static get scopes(): string[];

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

static get servicePath(): string;

The DNS address for this API service.

speechTranslationServiceStub

speechTranslationServiceStub?: Promise<{
        [name: string]: Function;
    }>;

warn

warn: (code: string, message: string, warnType?: string) => void;

Methods

close()

close(): Promise<void>;

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns
TypeDescription
Promise<void>

{Promise} A promise that resolves when the client is closed.

getProjectId()

getProjectId(): Promise<string>;
Returns
TypeDescription
Promise<string>

getProjectId(callback)

getProjectId(callback: Callback<string, undefined, undefined>): void;
Parameter
NameDescription
callback Callback<string, undefined, undefined>
Returns
TypeDescription
void

initialize()

initialize(): Promise<{
        [name: string]: Function;
    }>;

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns
TypeDescription
Promise<{ [name: string]: Function; }>

{Promise} A promise that resolves to an authenticated service stub.

streamingTranslateSpeech(options)

streamingTranslateSpeech(options?: CallOptions): gax.CancellableStream;

Performs bidirectional streaming speech translation: receive results while sending audio. This method is only available via the gRPC API (not REST).

Parameter
NameDescription
options CallOptions

Call options. See CallOptions for more details.

Returns
TypeDescription
gax.CancellableStream

{Stream} An object stream which is both readable and writable. It accepts objects representing [StreamingTranslateSpeechRequest] for write() method, and will emit objects representing [StreamingTranslateSpeechResponse] on 'data' event asynchronously. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#bi-directional-streaming) for more details and examples.

Example 

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  Provides information to the recognizer that specifies how to process the
   *  request. The first `StreamingTranslateSpeechRequest` message must contain
   *  a `streaming_config` message.
   */
  // const streamingConfig = {}
  /**
   *  The audio data to be translated. Sequential chunks of audio data are sent
   *  in sequential `StreamingTranslateSpeechRequest` messages. The first
   *  `StreamingTranslateSpeechRequest` message must not contain
   *  `audio_content` data and all subsequent `StreamingTranslateSpeechRequest`
   *  messages must contain `audio_content` data. The audio bytes must be
   *  encoded as specified in `StreamingTranslateSpeechConfig`. Note: as with
   *  all bytes fields, protobuffers use a pure binary representation (not
   *  base64).
   */
  // const audioContent = 'Buffer.from('string')'

  // Imports the Mediatranslation library
  const {SpeechTranslationServiceClient} =
    require('@google-cloud/media-translation').v1beta1;

  // Instantiates a client
  const mediatranslationClient = new SpeechTranslationServiceClient();

  async function callStreamingTranslateSpeech() {
    // Construct request
    const request = {};

    // Run request
    const stream = await mediatranslationClient.streamingTranslateSpeech();
    stream.on('data', response => {
      console.log(response);
    });
    stream.on('error', err => {
      throw err;
    });
    stream.on('end', () => {
      /* API call completed */
    });
    stream.write(request);
    stream.end();
  }
