Learn how to integrate Android’s built-in speech recognition API using RecognizerIntent and handle the results in your Jetpack Compose UI.
Understand how to request and check for the RECORD_AUDIO permission at runtime using Android’s permission system with ActivityCompat.
Build a modern UI with Jetpack Compose components including Button, BasicTextField, and Scaffold to create an interactive speech-to-text interface.
Use the modern ActivityResultContracts API with rememberLauncherForActivityResult to handle speech recognition callbacks in a Compose-friendly way.
The tutorial includes complete code examples that you can copy and adapt for your own projects. All source code is available in the GitHub repository.

Prerequisites

Before starting the tutorial, make sure you have:
  • Android Studio installed (latest stable version recommended)
  • Basic knowledge of Kotlin programming
  • Familiarity with Jetpack Compose fundamentals
  • An Android device or emulator for testing (API level 24+)
Speech recognition works best on physical devices. While you can use an emulator, some features may be limited depending on your emulator configuration.
