+ # CSS100-LJSpeech (Japanese / Meian)
17
+
18
+ **css100-ljspeech** は、Park *et al.* が公開した [CSS10](https://github.com/Kyubyong/css10) 日本語コーパス（明暗）を、LJ Speech 互換フォーマット (``id|text`` & ``wavs/*.wav``) へ変換した派生データセットです。

43
+
44
+ ```python
45
+ from datasets import load_dataset, Audio
46
+
47
+ ds = load_dataset("your-username/css100-ljspeech", split="train", streaming=True)
48
+ # ``id`` と ``text`` の 2 カラムがあり、``audio`` は "wavs/{id}.wav" を自動デコード
49
+ sample = next(iter(ds.cast_column("audio", Audio(sampling_rate=22050))))
50
+ print(sample["id"], sample["text"])
51
+ print(sample["audio"].keys()) # array, sampling_rate など
52
+ ```

+
