Client libraries

While you can use Speech-to-Text by making direct requests, we provide client libraries for several popular languages. Speech-to-Text client libraries are built on Google Cloud Client Libraries. This common infrastructure provides functionality for API-specific library implementations, but it also provides types and methods that you may use directly when using any Cloud API.

Available client libraries

Speech-to-Text provides client libraries and guides for the following languages:

Python

To learn how to install and use the client library for Speech-to-Text, see Speech-to-Text client libraries. For more information, see the Speech-to-Text Python API reference documentation.

To authenticate to Speech-to-Text, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.

This page provides reference documentation and related resources for the Speech-to-Text Python client library.

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

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-speech:4.48.0'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-speech" % "4.48.0"

If you're using Visual Studio Code, IntelliJ, or Eclipse, you can add client libraries to your project using the following IDE plugins:

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.
