Class v1.SpeechClient (6.3.0)

Service that implements Google Cloud Speech API. v1

Package

Constructors

(constructor)(opts, gaxInstance)

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

Construct an instance of SpeechClient.

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 SpeechClient({fallback: true}, gax); ```

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
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 StreamingRecognizeRequest 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 `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').v1;

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

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

    // Run request
    const stream = await speechClient.streamingRecognize();

cancelOperation(request, options, callback)

cancelOperation(request: protos.google.longrunning.CancelOperationRequest, options?: gax.CallOptions | Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} | undefined | null>, callback?: Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} | undefined | null>): Promise<protos.google.protobuf.Empty>;

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an value with a of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
`request`	`CancelOperationRequest` The request object that will be sent.
`options`	`CallOptions \| Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} \| undefined \| null>` Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
`callback`	`Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} \| undefined \| null>` The function which will be called with the result of the API call. {Promise} - The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.

Returns
Type	Description
`Promise<protos.google.protobuf.Empty>`

Example


const client = longrunning.operationsClient();
await client.cancelOperation({name: ''});

checkLongRunningRecognizeProgress(name)

checkLongRunningRecognizeProgress(name: string): Promise<LROperation<protos.google.cloud.speech.v1.LongRunningRecognizeResponse, protos.google.cloud.speech.v1.LongRunningRecognizeMetadata>>;

Returns
Type	Description
`Promise<LROperation<protos.google.cloud.speech.v1.LongRunningRecognizeResponse, protos.google.cloud.speech.v1.LongRunningRecognizeMetadata>>`	{Promise} - The promise which resolves to an object. The decoded operation object has result and metadata field to get information from. Please see the documentation for more details and examples.
