Overview
Sherpa-ONNX Web enables speech recognition and synthesis in web applications using WebAssembly. It brings the capabilities of Sherpa-ONNX—such as automatic speech recognition (ASR), text-to-speech (TTS), and speech-to-text (STT)—to the browser environment without requiring native code. This package allows developers to integrate real-time voice processing directly into web apps, ideal for voice assistants, transcription tools, and interactive audio interfaces. The WebAssembly-based implementation ensures high performance and compatibility across modern browsers.
