## 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 v3.1](https://arxiv.org/abs/2401.16658) is an improved version of OWSM v3. It significantly outperforms OWSM v3 in almost all evaluation benchmarks.
We do not include any new training data. Instead, we utilize a state-of-the-art speech encoder, [E-Branchformer](https://arxiv.org/abs/2210.00077).

**This is a small size model with 367M parameters and is trained on 70k hours of public speech data with lower restrictions (compared to the full OWSM data).** Please check our [project page](https://www.wavlab.org/activities/2024/owsm/) for more information.
Specifically, it supports the following speech-to-text tasks:
- Speech recognition
- Utterance-level alignment
- Long-form transcription
- Language identification
