| # Minspeech (Southern Min) |
|
|
| Full `train`/`dev`/`test` transfer of the [Minspeech](https://minspeech.github.io/) Southern |
| Min (Taiwanese) speech corpus, staged from an internal COS copy. `unlabeled` is still just a |
| 10-clip illustrative preview -- see "Splits" below. |
|
|
| ## Dataset Description |
|
|
| - **Use case**: ASR (Automatic Speech Recognition) |
| - **Language**: spoken audio is Southern Min / Taiwanese (drama dialogue); the transcript |
| (`mandarin`) is written in Mandarin Chinese, not Taiwanese Han-lo -- **the two are |
| different languages**, matching the official Minspeech release as-is. |
| - **Source**: [Minspeech](https://minspeech.github.io/) official corpus (Southern Min TV |
| drama), re-cropped to match the official splits exactly. See "Splits" below for details. |
| - **Audio format**: 16kHz, mono, PCM WAV |
| - **Split**: 4 splits, see below. |
|
|
| ## Dataset Structure |
|
|
| - `id`: official Minspeech utterance ID (`S<series><episode><utterance>` for `train`/`dev`/ |
| `test`; source video ID for `unlabeled`). |
| - `audio`: audio clip (16kHz mono WAV), spoken in Southern Min / Taiwanese. |
| - `mandarin`: **Mandarin Chinese** transcript, exactly as released in the official `*_text` |
| files. Not a Taiwanese-script transcription of the audio. Empty for `unlabeled` (see below). |
|
|
| ### Splits |
|
|
| - `train` / `dev` / `test`: **full** official Minspeech ASR splits, utterance-level clips |
| with transcripts, matching the official `*_wav.scp` / `*_text` files. One source episode |
| (`S01142`) failed to parse and was skipped -- everything else is included. |
| - `unlabeled`: raw, **not utterance-segmented** source video audio with no transcript |
| (`mandarin` is an empty string). The original Minspeech release ships only a video ID list |
| for this portion and expects users to run their own VAD (the authors suggest |
| [silero-vad](https://github.com/snakers4/silero-vad)) to cut it into utterances. **This is |
| still just a 10-clip preview** (20-second excerpts from the start of 10 source videos, for |
| illustration only) -- the full `unlabeled` split (807GB of raw video audio) hasn't been |
| uploaded yet. |

| ## Statistics |
|
|
| | **split** | **lang_name** | **hours** | **n_utts** | **n_chars_in_utts** | **secs/utt** | **chars/sec** | **n_sents** | **n_chars_in_sents** | |
| | --- | --- | --- | --- | --- | --- | --- | --- | --- | |
| | train | Taigi | 1692.21 | 2614243 | 20301907 | 2.33 | 3.33 | 0 | 0 | |
| | dev | Taigi | 16.7259 | 25671 | 201198 | 2.35 | 3.34 | 0 | 0 | |
| | test | Taigi | 18.509 | 28685 | 219051 | 2.32 | 3.29 | 0 | 0 | |
| | unlabeled | Taigi | 0.0556 | 10 | 0 | 20.02 | 0 | 0 | 0 | |
| | **Total** | **-** | **1727.4995** | **2668609** | **20722156** | **2.33** | **3.33** | **0** | **0** | |
| |
| `dev`/`test`/`unlabeled` are computed exactly (every row scanned). **`train`'s `hours`/ |
| `n_chars_in_utts` are estimated** from a spread sample of 48 of its 1186 shards (~4%) and |
| scaled up to the exact row count (2,614,243, from the Hub's own row-count metadata) -- |
| scanning all 1186 shards' audio in full wasn't done here since it would mean re-downloading |
| ~178GB just to compute stats. `secs/utt` and `chars/sec` are stable across the sampled |
| shards (2.3-2.4s/utt, ~3.3 chars/sec throughout), so the estimate should be accurate to |
| within a percent or two, but treat the `train` row as an estimate, not an exact count. |
