### Commonvoice Cantonese (zh-HK) Char training results (Zipformer)
|
||||
|
||||
See #1542 for more details.

|
||||
Number of model parameters: 72526519, i.e., 72.53 M
|
||||
|
||||
The best CER, for CommonVoice 16.1 (cv-corpus-16.1-2023-12-06/zh-HK) is below:

To reproduce the above result, use the following commands for training:
|
||||
|
||||
```bash
|
||||
export CUDA_VISIBLE_DEVICES="0,1"
|
||||
./zipformer/train_char.py \
|
||||

|
||||
--context-size 1 \
|
||||
--max-duration 1000
|
||||
```
|
||||
|
||||
and the following commands for decoding:
|
||||
|
||||
```bash
|
||||
for method in greedy_search modified_beam_search fast_beam_search; do
|
||||
./zipformer/decode_char.py \
