| # iFormosa |
|
|
| iFormosa（閩南語文數位教材）Southern Min digital teaching material -- read-aloud passages |
| with Taiwanese (Han-lo) transcripts and Mandarin translations. |
|
|
| ## Dataset Description |
|
|
| - **Use case**: ASR (Automatic Speech Recognition) |
| - **Language**: Taiwanese (Southern Min), Han-lo (漢羅) script |
| - **Source**: reshaped from `ds/iformosa-ts-ds.zip` (a `datasets` arrow-format export on the |
| source COS bucket) into HF-viewer-friendly Parquet shards. The original source |
| (`scraps/oneai/iformosa/`) shows richer per-word annotation (Han-lo + Tai-lo romanization |
| per word) than what made it into this arrow export; only the whole-sentence `tw`/`zh` |
| pair survived into this repo. |
| - **Known content overlap**: at least one passage ("阿公，行啦！咱來去騎鐵馬...") is |
| identical to an entry in `NickWeng/llotg-jenpin-knsh` (its jen-pin/"國中組_騎鐵馬" source) |
| -- the two corpora likely draw from the same underlying reading-text bank in places. Not |
| deduplicated across repos; if you're combining both for training, check for duplicate |
| text/audio content. |
| - **Audio format**: 16kHz, mono, 16-bit PCM WAV |
| - **Split**: this dataset is `train` only. |
| |
| ## Dataset Structure |
| |
| - `id`: source utterance identifier (already unique, e.g. `1090101_0-3`). |
| - `audio`: audio clip (16kHz, mono, 16-bit PCM WAV). |
| - `text`: Taiwanese transcript, Whisper-style inline timestamp tokens stripped (same |
| language/script as the audio, per this project's field-naming convention). |
| - `text_timestamped`: the same transcript with the original inline Whisper timestamp |
| tokens preserved untouched. |
| - `mandarin`: Mandarin translation of the same passage. **Empty for 97 of 316 rows** (no |
| translation was available in the source for those passages -- not a data error). |
| - `mandarin_timestamped`: the same, with original inline timestamp tokens preserved |
| (also empty where `mandarin` is empty). |
