    Cloud Speech Client Library for Node.js

    A comprehensive list of changes in each version may be found in the CHANGELOG.

    Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

    Table of contents:

    Quickstart

    Before you begin

    1. Select or create a Cloud Platform project.
    2. Enable the Cloud Speech API.
    3. Set up authentication with a service account so you can access the API from your local workstation.

    Installing the client library

    npm install @google-cloud/speech

    Using the client library

    // Imports the Google Cloud client library
    const speech = require('@google-cloud/speech');
    
    // Creates a client
    const client = new speech.SpeechClient();
    
    async function quickstart() {
      // The path to the remote LINEAR16 file
      const gcsUri = 'gs://cloud-samples-data/speech/brooklyn_bridge.raw';
    
      // The audio file's encoding, sample rate in hertz, and BCP-47 language code
      const audio = {
        uri: gcsUri,
      };
      const config = {
        encoding: 'LINEAR16',
        sampleRateHertz: 16000,
        languageCode: 'en-US',
      };
      const request = {
        audio: audio,
        config: config,
      };
    
      // Detects speech in the audio file
      const [response] = await client.recognize(request);
      const transcription = response.results
        .map(result => result.alternatives[0].transcript)
        .join('\n');
      console.log(`Transcription: ${transcription}`);
    }
    quickstart();

    Samples

    Samples are in the samples/ directory. Each sample's README.md has instructions for running its sample.

    Sample Source Code Try it

    Supported Node.js Versions

    Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

    Client libraries targeting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

    Legacy Node.js versions are supported as a best effort:

    • Legacy versions will not be tested in continuous integration.
    • Some security patches may not be able to be backported.
    • Dependencies will not be kept up-to-date, and features will not be backported.

    Legacy tags available

    • legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

    Versioning

    This library follows Semantic Versioning.

    This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
