Minspeech (Southern Min)
Full train/dev/test transfer of the Minspeech Southern
Min (Taiwanese) speech corpus, staged from an internal COS copy. unlabeled is still just a
10-clip illustrative preview -- see "Splits" below.
Dataset Structure
id: official Minspeech utterance ID (S<series><episode><utterance>fortrain/dev/test; source video ID forunlabeled).audio: audio clip (16kHz mono WAV), spoken in Southern Min / Taiwanese.mandarin: Mandarin Chinese transcript, exactly as released in the official*_textfiles. Not a Taiwanese-script transcription of the audio. Empty forunlabeled(see below).
Splits
train/dev/test: full official Minspeech ASR splits, utterance-level clips with transcripts, matching the official*_wav.scp/*_textfiles. 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 (mandarinis 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) 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 fullunlabeledsplit (807GB of raw video audio) hasn't been uploaded yet.

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.
