# Librispeech-PC (punctuation and capitalization restored) |
|
|
|
|
|
### Original Dataset can be found in <https://www.openslr.org/145/> |
|
|
|
- I made it for personal use, so the code might not be pefect. |
|
|
|
|
|
|
|
### How to Use |
|
|
|
- Almost the same with [Librispeech](https://huggingface.co/datasets/openslr/librispeech_asr) dataset module since i refered to its [source code](https://huggingface.co/datasets/openslr/librispeech_asr/blob/main/librispeech_asr.py). |
|
|
|
- three types of transcripts are given |
|
- `text_normalized` : the trascript from Librispeech ASR |
|
- `text`, `text_raw` : the trascripts from Librispeech-PC |
|
|
|
|
|
```python |
|
from datasets import load_dataset |
|
from pprint import pprint |
|
from IPython.display import display, Audio |
|
import aiohttp |
|
import os |
|
|
|
# set huggingface cache directory for the extracted raw files and huggingface-cli token |
|
# if don't, you might download the raw tar.gz file in home cache dir even if you set `cache_dir` param |
|
os.environ['HF_HOME'] = "/data_dir/to/download" |
|
!export HF_HOME="/data_dir/to/download" |
|
|
|
|
|
# download dataset |
|
# if already have librispeech_asr in the cache_dir it will use the same audio files. |
|
libripc = load_dataset("yoom618/librispeech_pc", |
|
"all", # all, clean, other |
|
cache_dir="/data_dir/to/download", |
|
trust_remote_code=True, |
|
# storage_options={ |
|
# # add if you need to increase the timeout for openslr download |
|
# 'client_kwargs': {'timeout': aiohttp.ClientTimeout(total=7200)} |
|
# }, |
|
) |
|
|
|
|
|
# check dataset info |
|
print(libripc) |
|
|
|
display(Audio(libripc['train.clean.100'][0]['audio']['array'], |
|
rate=libripc['train.clean.100'][0]['audio']['sampling_rate'], |
|
autoplay=False)) |
|
pprint(libripc['train.clean.100'][0]['audio']) |
|
