Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Cloud Media Translation API.
4. Set up authentication so you can access theAPI from your local workstation.

Installing the client library

npm install @google-cloud/media-translation

Using the client library

const fs = require('fs');// Imports the CLoud Media Translation client libraryconst {  SpeechTranslationServiceClient,} = require('@google-cloud/media-translation');// Creates a clientconst client = newSpeechTranslationServiceClient();async function quickstart() {  /**   * TODO(developer): Uncomment the following lines before running the sample.   */  // const filename = 'Local path to audio file, e.g. /path/to/audio.raw';  // const encoding = 'Encoding of the audio file, e.g. LINEAR16';  // const sourceLanguage = 'BCP-47 source language code, e.g. en-US';  // const targetLanguage = 'BCP-47 target language code, e.g. es-ES';  const config = {    audioConfig: {      audioEncoding: encoding,      sourceLanguageCode: sourceLanguage,      targetLanguageCode: targetLanguage,    },  };  // First request needs to have only a streaming config, no data.  const initialRequest = {    streamingConfig: config,    audioContent: null,  };  const readStream = fs.createReadStream(filename, {    highWaterMark: 4096,    encoding: 'base64',  });  const chunks = [];  readStream    .on('data', chunk => {      const request = {        streamingConfig: config,        audioContent: chunk.toString(),      };      chunks.push(request);    })    .on('close', () => {      // Config-only request should be first in stream of requests      stream.write(initialRequest);      for (let i = 0; i < chunks.length; i++) {        stream.write(chunks[i]);      }      stream.end();    });  const stream = client.streamingTranslateSpeech().on('data', response => {    const {result} = response;    if (result.textTranslationResult.isFinal) {      console.log(        `\nFinal translation: ${result.textTranslationResult.translation}`      );      console.log(`Final recognition result: ${result.recognitionResult}`);    } else {      console.log(        `\nPartial translation: ${result.textTranslationResult.translation}`      );      console.log(`Partial recognition result: ${result.recognitionResult}`);    }  });

Supported Node.js Versions

Our client libraries follow theNode.js release schedule.Libraries are compatible with all currentactive andmaintenance versions ofNode.js.If you are using an end-of-life version of Node.js, we recommend that you updateas soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on abest-efforts basis with the following warnings:

• Legacy versions are not tested in continuous integration.
• Some security patches and features cannot be backported.
• Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, andcan be installed through npmdist-tags.The dist-tags follow the naming conventionlegacy-(version).For example,npm install @google-cloud/media-translation@legacy-8 installs client librariesfor versions compatible with Node.js 8.

Versioning

This library followsSemantic Versioning.

This library is considered to bestable. The code surface will not change in backwards-incompatible waysunless absolutely necessary (e.g. because of critical security issues) or withan extensive deprecation period. Issues and requests againststable librariesare addressed with the highest priority.
