Java idiomatic client forCloud Speech.

• Product Documentation
• Client Library Documentation

🚌 In October 2022, this library has moved togoogle-cloud-java/java-speech.This repository will be archived in the future.Future releases will appear in the new repository (https://github.com/googleapis/google-cloud-java/releases).The Maven artifact coordinates (com.google.cloud:google-cloud-speech) remain the same.

If you are using Maven withBOM, add this to your pom.xml file:

<dependencyManagement>  <dependencies>    <dependency>      <groupId>com.google.cloud</groupId>      <artifactId>libraries-bom</artifactId>      <version>26.1.3</version>      <type>pom</type>      <scope>import</scope>    </dependency>  </dependencies></dependencyManagement><dependencies>  <dependency>      <groupId>org.json</groupId>      <artifactId>json</artifactId>      <version>20220924</version>  </dependency>  <dependency>    <groupId>com.google.cloud</groupId>    <artifactId>google-cloud-speech</artifactId>  </dependency></dependencies>

If you are using Maven without BOM, add this to your dependencies:

<dependency>  <groupId>com.google.cloud</groupId>  <artifactId>google-cloud-speech</artifactId>  <version>2.6.1</version></dependency>

If you are using Gradle 5.x or later, add this to your dependencies:

implementation platform('com.google.cloud:libraries-bom:26.1.4')implementation'com.google.cloud:google-cloud-speech'

If you are using Gradle without BOM, add this to your dependencies:

implementation'com.google.cloud:google-cloud-speech:4.1.0'

If you are using SBT, add this to your dependencies:

libraryDependencies+="com.google.cloud"%"google-cloud-speech"%"4.1.0"

See theAuthentication section in the base directory's README.

The client application making API calls must be grantedauthorization scopes required for the desired Cloud Speech APIs, and the authenticated principal must have theIAM role(s) required to access GCP resources using the Cloud Speech API calls.

You will need aGoogle Cloud Platform Console project with the Cloud SpeechAPI enabled.

Follow these instructions to get your project set up. You will also need to set up the local development environment byinstalling the Google Cloud SDK and running the following commands in command line:gcloud auth login andgcloud config set project [YOUR PROJECT ID].

You'll need to obtain thegoogle-cloud-speech library. See theQuickstart sectionto addgoogle-cloud-speech as a dependency in your code.

Cloud Speech enables easy integration of Google speech recognition technologies into developer applications. Send audio and receive a text transcription from the Speech-to-Text API service.

See theCloud Speech client library docs to learn how touse this Cloud Speech Client Library.

The following code sample shows how to recognize speech using an audio file from a Cloud Storage bucket as input.First, add the following imports at the top of your file:

importcom.google.cloud.speech.v1.SpeechClient;importcom.google.cloud.speech.v1.RecognitionAudio;importcom.google.cloud.speech.v1.RecognitionConfig;importcom.google.cloud.speech.v1.RecognitionConfig.AudioEncoding;importcom.google.cloud.speech.v1.RecognizeResponse;

Then add the following code to do the speech recognization:

try (SpeechClientspeechClient =SpeechClient.create()) {RecognitionConfig.AudioEncodingencoding =RecognitionConfig.AudioEncoding.FLAC;intsampleRateHertz =44100;StringlanguageCode ="en-US";RecognitionConfigconfig =RecognitionConfig.newBuilder()     .setEncoding(encoding)     .setSampleRateHertz(sampleRateHertz)     .setLanguageCode(languageCode)     .build();Stringuri ="gs://bucket_name/file_name.flac";RecognitionAudioaudio =RecognitionAudio.newBuilder()     .setUri(uri)     .build();RecognizeResponseresponse =speechClient.recognize(config,audio); }

InRecognizeSpeech.java we put a quick start example, which shows how you can use Google Speech API to automatically recognize speech based on a local file.

For an example audio file, you can use theaudio.raw file from the samples repository.Note, to play the file on Unix-like system you may use the following command:play -t raw -r 16k -e signed -b 16 -c 1 audio.raw

Samples are in thesamples/ directory.

Cloud Speech uses gRPC for the transport layer.

Java 8 or above is required for using this client.

Google's Java client libraries,Google Cloud Client LibrariesandGoogle Cloud API Libraries,follow theOracle Java SE support roadmap(see the Oracle Java SE Product Releases section).

In general, new feature development occurs with support for the lowest JavaLTS version covered by Oracle's Premier Support (which typically lasts 5 yearsfrom initial General Availability). If the minimum required JVM for a givenlibrary is changed, it is accompanied by asemver major release.

Java 11 and (in September 2021) Java 17 are the best choices for newdevelopment.

Google tests its client libraries with all current LTS versions covered byOracle's Extended Support (which typically lasts 8 years from initialGeneral Availability).

Google's client libraries support legacy versions of Java runtimes with longterm stable libraries that don't receive feature updates on a best efforts basisas it may not be possible to backport all patches.

Google provides updates on a best efforts basis to apps that continue to useJava 7, though apps might need to upgrade to current versions of the librarythat supports their JVM.

The latest versions and the supported Java versions are identified onthe individual GitHub repositorygithub.com/GoogleAPIs/java-SERVICENAMEand ongoogle-cloud-java.

This library followsSemantic Versioning.
