| # Irodori TTS Reference Voices (10K) |
|
|
| 10,000 synthetic Japanese reference voices generated with the |
| [Irodori-TTS-500M-v2-VoiceDesign](https://huggingface.co/Aratako/Irodori-TTS-500M-v2-VoiceDesign) |
| model from voice-design captions (no reference audio — `no_ref=True`). |
|
|
| Each row is one unique speaker. |
|
|
| ## Columns |
|
|
| | column | type | description | |
| |---|---|---| |
| | `audio` | Audio(48kHz mono) | reference waveform | |
| | `text` | string | Japanese utterance with emoji prosody cues | |
| | `speaker_id` | string | `speaker_00001` … `speaker_10000` | |
