| # aishell3-ready |
|
|
| Mandarin Chinese multi-speaker speech from **AISHELL-3** (Beijing Shell Shell Technology Co., Ltd., Apache License 2.0), repackaged as 24 kHz FLAC-in-parquet shards for TTS and aligner training. |
|
|
| | Item | Value | |
| |---|---| |
| | Source | AISHELL-3 (44.1 kHz, 218 native Mandarin speakers, ~85 h) | |
| | Rows | 88,035 utterances | |
| | Audio | 24 kHz mono FLAC bytes in `audio` (resampled from 44.1 kHz, even-length trimmed) | |
| | Shards | 45 × `part-NNNNN.parquet` (2,000 rows each) | |
| | Columns | `uid`, `audio`, `num_samples`, `sampling_rate`, `text`, `phonemes`, `speaker`, `speaker_id`, `language`, `split` | |
| | Sidecars | `_v9/` phoneme sidecars (IPA symbol strings with Mandarin tone marks, stress, word index, character spans), joined on `uid` | |
|
|
| `speaker` keeps the AISHELL-3 speaker code (`aishell3:SSB0005`, …). A companion repository `dabsdamoon/aishell3-ready-f0` adds pre-extracted CREPE pitch columns to the same rows. |
