| # TATTS | |
| Synthetic Taiwanese Hokkien speech paired with written Mandarin targets. This | |
| release is intended for **listening in Taiwanese Hokkien and writing Mandarin** | |
| (S2TT); `text` is therefore the Mandarin training target, while `tailo_hant` | |
| and `tailo_pinyin` describe the spoken content. The labels were not replaced | |
| during packaging. | |
| This is the latest fully frozen and audited snapshot from the ongoing Hua/Tailo | |
| TTS pipeline. New generated rows are published only after the same integrity | |
| checks have completed, so a live partial batch is never mixed into this release. | |
| ## Release statistics | |
| - Rows: 106,325 | |
| - Audio: 233.385 hours | |
| - Unique Mandarin targets: 4,253 | |
| - Variants per target: 25: 4,253 targets | |
| - Audio Parquet shards: 30 | |
| - Audio encoding: FLAC, PCM16, 16 kHz, mono | |
| ## Configs and columns | |
| The `audio` config is directly loadable with Hugging Face Datasets and embeds | |
| FLAC bytes. Important columns are `audio`, `text`, `tailo_hant`, | |
| `tailo_pinyin`, `lang`, `duration`, source/provenance identifiers, speaker | |
| attributes, and augmentation parameters. | |
| The `corpus` config contains the same public metadata without binary audio. | |
| Its `audio_filepath` values are portable Parquet row locators such as | |
| `audio/nan_based_on_zh/train/part-....parquet#row=N`; no cluster-local absolute | |
| paths are published. | |
| ## Packaging validation | |
| Every frozen source row had a unique ID and audio path, accepted pipeline | |
| statuses, and a complete 25-variant target group. Every FLAC was checked | |
| against its recorded byte size and SHA256, fully decoded, confirmed non-silent | |
| PCM16 at 16 kHz mono, and checked against metadata duration within 1.01 audio | |
| samples. The Parquet files copied from node-local staging were verified again | |
| by SHA256 before publication readiness was marked. | |
| This corpus contains synthetic and augmented speech. Review the upstream data | |
| and voice-reference licensing/provenance before redistribution or commercial | |
| use; the package does not claim a permissive blanket license. | |
