Class v1beta1.SpeechTranslationServiceClient (4.0.2)

Provides translation from/to media types. v1beta1

Package

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of SpeechTranslationServiceClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof fallback` : loaded instance of `google-gax`. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new SpeechTranslationServiceClient({fallback: true}, gax); ```

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
Type	Description
`Promise<void>`	{Promise} A promise that resolves when the client is closed.

getProjectId()

getProjectId(): Promise<string>;

Returns
Type	Description
`Promise<string>`

getProjectId(callback)

getProjectId(callback: Callback<string, undefined, undefined>): void;

Parameter
Name	Description
`callback`	`Callback<string, undefined, undefined>`

Returns
Type	Description
`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
Type	Description
`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
Name	Description
`options`	`CallOptions` Call options. See CallOptions for more details.

Returns
Type	Description
`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 on 'data' event asynchronously. Please see the documentation for more details and examples.

Example


  /**
   * 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.
   * 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();
