|
| # How to use |
| ## Requirements |
| The dataet loading will require following python libraries. |
| * [lhotse](https://github.com/lhotse-speech/lhotse) |
| * [webdataset](https://github.com/webdataset/webdataset) |
| * If you need transcription, [smart-open](https://github.com/getcrest/smart-open) |
| ## loading dataset |
| Please see the following to load the dataset as `lhotse.CutSet` |
|
|
| ### Without transcription |
| ```python |
| import lhotse |
| |
| # change the following line to the subset and the data domain you like. |
| # For data domain the options are youtube and podcast. |
| # For subset, train, valid, test, others are available. |
| # For instance, if you want to get data from youtube test set. the filepath would be filelists/yotube_test.txt |
| with open("filelists/podcast_train.txt") as f: |
| urls = f.read().splitlines() |
| |
| cutset = lhotse.CutSet.from_webdataset(urls) |
| ``` |
|
|
| ### With transcription |
| ```python |
| import json |
| import lhotse |
| |
| with open("transcribed_jchat/podcast_train.json") as f: |
| fields = json.load(f) |
| |
| cuts = lhotse.CutSet.from_shar(fields=fields) |
| |
