# VoxBox
This dataset is a curated collection of bilingual speech corpora annotated clean transcriptions and rich metadata incluing age, gender, and emotion.
## Dataset Structure
```bash
.
├── audios/
│ └── aishell-3/ # Audio files (organised by sub-corpus)
│ └── ...
└── metadata/
├── aishell-3.jsonl
├── casia.jsonl
├── commonvoice_cn.jsonl
├── ...
└── wenetspeech4tts.jsonl # JSONL metadata files
```
Each JSONL file corresponds to a specific corpus and contains one metadata record per audio sample.
## Metadata Format
Each line in the *.jsonl files is a JSON object describing one audio sample. Below is a typical example:
```json
{
"index": "VCTK_0000044280",
"split": "train",
"language": "en",
"age": "Youth-Adult",
"gender": "female",
"emotion": "UNKNOWN",
"pitch": 180.626,
"pitch_std": 0.158,
"speed": 4.2,
"duration": 3.84,
"speech_duration": 3.843,
"syllable_num": 16,
"text": "Clearly, the need for a personal loan is written in the stars.",
"syllables": "K-L-IH1-R L-IY0 DH-AH0 N-IY1-D F-AO1 R-AH0 P-ER1 S-IH0 N-IH0-L L-OW1 N-IH1 Z-R-IH1 T-AH0 N-IH0-N DH-AH0-S T-AA1-R-Z",
"wav_path": "vctk/VCTK_0000044280.flac"
}
```
The corresponding audio file is located inside the extracted .tar.gz archive.
**Key Fields:**
- `index`: Unique identifier for the audio sample.
- `split`: Train/test split.
- `language`: Language of the audio sample. Currently only English and Chinese are supported.
- `age`, `gender`, `emotion`: Speaker and utterance attributes
- `pitch`, `pitch_std`, `speed`: Acoustic features
- `duration`: Duration of the audio sample in seconds
- `speech_duration`: Duration of the speech in seconds by excluding silence in both ends.
- `syllable_num`: Number of syllables in the utterance
- `text`: Transcription of the utterance
- `syllables`: Syllable-level transcription
- `wav_path`: Path to the audio file
