- A speech recognizer built on Vosk that can be run on the browser, inspired by vosk-browser, but built from scratch and no code taken!
- Designed with basic/nothrow exception safety
- See the examples folder for examples on using the API.
- See API.md for the API reference
- See test for a developer build script for just the JS
- Support multiple models
- Has models' storage path management
- Has models' ID management (for model updates)
- Has smaller JS size (>3.1MB vs 1.4MB gzipped)
- Has all related files (pthread worker, audio worklet processor,...) merged
- Has faster processing time
- Has shorter from-scratch build time
- Has more Vosk functions exposed
- Result are logged to the console.
- Copied from examples/fromMic.html
