| ## Introduction |
|
|
|
|
| This is a medium [zipformer](https://arxiv.org/pdf/2310.11230) model developed by Xiaomi AI Lab Next-gen-Kaldi team. The model was trained on around 20,0000 hours of open-sourced Chinese and English datasets. The number of parameters is around 68M (for ctc head), 73M (for transducer head). |
