# talkbank/callhome for JA plus

[talkbank/callhome](https://huggingface.co/datasets/talkbank/callhome)のJAデータをwavに変換して、metaデータをjsonにまとめたデータセット

## meta data

以下のようなデータ構造の配列になっています

```json
    {
        "audio_filename": "callhome_jpn_0.wav",
        "sampling_rate": 16000,
        "duration": 606.53,
        "utterances": [
            {
                "start_time": 0.0,
                "end_time": 3.4799999999999898,
                "speaker": "B"
            },
            {
                "start_time": 1.5999999999999943,
                "end_time": 2.059999999999988,
                "speaker": "A"
            }
            ...
        ]
    }
```

評価用にrttmファイルも追加しています

```rttm
SPEAKER callhome_jpn_0 1 0.000 3.480 <NA> <NA> B <NA> <NA>
SPEAKER callhome_jpn_0 1 1.600 0.460 <NA> <NA> A <NA> <NA>
```
