## OWSM: Open Whisper-style Speech Model

[OWSM](https://arxiv.org/abs/2309.13876) is an Open Whisper-style Speech Model from [CMU WAVLab](https://www.wavlab.org/). It reproduces Whisper-style training using publicly available data and an open-source toolkit [ESPnet](https://github.com/espnet/espnet).

Our demo is available [here](https://huggingface.co/spaces/pyf98/OWSM_v3_demo). The [project page](https://www.wavlab.org/activities/2024/owsm/) contains various resources.

OWSM v3 has 889M parameters and is trained on 180k hours of public speech data. It supports various speech-to-text tasks:
- Speech recognition
- Any-to-any-language speech translation
- Utterance-level alignment
- Long-form transcription
- Language identification

For more details and results, please check out our [paper](https://arxiv.org/abs/2309.13876) (Peng et al., ASRU 2023).
