Speech recognition
A Capacitor plugin for native speech recognition on iOS and Android, enabling voice-to-text in hybrid mobile apps.
What is Speech recognition?
Capacitor Speech Recognition Plugin is a native plugin that enables speech-to-text functionality in Capacitor-based hybrid mobile applications. It provides a JavaScript API to access iOS and Android's built-in speech recognition services, allowing developers to add voice input features without writing platform-specific code. The plugin handles permissions, language configuration, and real-time transcription results.
Mobile developers building hybrid apps with Capacitor/Ionic who need to integrate voice recognition features such as voice commands, dictation, or accessibility tools.
Developers choose this plugin because it offers a consistent, well-documented API for both major mobile platforms, eliminating the need to write separate native implementations. It simplifies permission handling and provides real-time transcription updates, making it easier to build responsive voice interfaces.
Overview
The Capacitor Speech Recognition Plugin provides a unified JavaScript API to access native speech recognition capabilities on iOS and Android devices. It allows hybrid mobile apps built with Capacitor to convert spoken language into text, enabling voice commands, dictation, and other voice-driven interactions.
Key Features
- Cross-Platform API — Consistent JavaScript interface for both iOS and Android speech recognition services.
- Partial Results Streaming — Real-time transcription updates via event listeners for immediate feedback.
- Permission Management — Built-in methods to check and request microphone and speech recognition permissions.
- Language Support — Ability to specify recognition language and retrieve supported language lists.
- Listening State Control — Methods to start, stop, and check if recognition is actively listening.
Philosophy
The plugin abstracts platform-specific speech recognition implementations into a simple, promise-based API, following Capacitor's design principles for bridging web and native functionality.
