## Data preparation
Refer to official [SLIDESPEECH CORPUS](https://slidespeech.github.io/)

The dataset requires four files: "my_wav.scp", "utt2num_samples", "text", "hot_related/ocr_1gram_top50_mmr070_hotwords_list".

"my_wav.scp" is a file of audio path lists. We transform wav file to ark file, so this file looks like:

```
ID1 xxx/slidespeech/dev_oracle_v1/data/format.1/data_wav.ark:22
ID2 xxx/slidespeech/dev_oracle_v1/data/format.1/data_wav.ark:90445
```

SLIDESPEECH provides "text" and a file named "keywords". The file "keywords" refers to "hot_related/ocr_1gram_top50_mmr070_hotwords_list", which contains hotwords lists.

"utt2num_samples" contains the length of the wavs, which looks like:

```
ID1 103680
ID2 181600
```

Please ensure that the order of all files is strictly consistent.

## Decode with checkpoints
```
