#### Smaller model
A smaller model (~20M params) is also available with configuration based on [this comment](https://github.com/k2-fsa/icefall/pull/745#issuecomment-1405282740). The WERs are:
| decoding method | chunk size | test-clean | test-other | comment | decoding mode |
|----------------------|------------|------------|------------|---------------------|----------------------|
| greedy search | 320ms | 3.94 | 9.79 | --epoch 30 --avg 9 | simulated streaming |
| modified beam search | 320ms | 3.88 | 9.53 | --epoch 30 --avg 9 | simulated streaming |
