sherpa-onnx is software for Speech-to-text, text-to-speech, speaker diarization, and VAD using next-gen Kaldi with onnxruntime without Internet connection.
This is free and open source software.
Features include:
- Speech-to-text (i.e., ASR); both streaming and non-streaming are supported.
- Text-to-speech (i.e., TTS).
- Speaker diarization.
- Speaker identification.
- Speaker verification.
- Spoken language identification.
- Audio tagging.
- VAD (e.g., silero-vad).
