Methods

_streamingRecognize(options)

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

Performs bidirectional streaming speech recognition: 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 [StreamingRecognizeRequest] for write() method, and will emit objects representing [StreamingRecognizeResponse] 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 `StreamingRecognizeRequest` message must contain a
   *  `streaming_config`  message.
   */
  // const streamingConfig = {}
  /**
   *  The audio data to be recognized. Sequential chunks of audio data are sent
   *  in sequential `StreamingRecognizeRequest` messages. The first
   *  `StreamingRecognizeRequest` message must not contain `audio_content` data
   *  and all subsequent `StreamingRecognizeRequest` messages must contain
   *  `audio_content` data. The audio bytes must be encoded as specified in
   *  `RecognitionConfig`. Note: as with all bytes fields, proto buffers use a
   *  pure binary representation (not base64). See
   *  content limits (https://cloud.google.com/speech-to-text/quotas#content).
   */
  // const audioContent = 'Buffer.from('string')'

  // Imports the Speech library
  const {SpeechClient} = require('@google-cloud/speech').v1p1beta1;

  // Instantiates a client
  const speechClient = new SpeechClient();

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

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

  callStreamingRecognize();

   *  process the request.
   */

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.

longRunningRecognize(request, options)

longRunningRecognize(request?: protos.google.cloud.speech.v1p1beta1.ILongRunningRecognizeRequest, options?: CallOptions): Promise<[LROperation<protos.google.cloud.speech.v1p1beta1.ILongRunningRecognizeResponse, protos.google.cloud.speech.v1p1beta1.ILongRunningRecognizeMetadata>, protos.google.longrunning.IOperation | undefined, {} | undefined]>;

Performs asynchronous speech recognition: receive results via the google.longrunning.Operations interface. Returns either an Operation.error or an Operation.response which contains a LongRunningRecognizeResponse message. For more information on asynchronous speech recognition, see the [how-to](https://cloud.google.com/speech-to-text/docs/async-recognize).

Parameters
NameDescription

{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its promise() method returns a promise you can await for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.
