Danish ASR (Common Voice 22, filtered + rebalanced)

Danish (da) speech for ASR, built from Mozilla Common Voice 22.0 (CC0) via the open `fsicoli/common_voice_22_0` mirror. Built to fine-tune streaming ASR models (e.g. nvidia/nemotron-3.5-asr-streaming-0.6b).

Splits

Split	Clips	Hours
train	8270	10.0
dev	734	0.9
test	1593	2.1

train = the official validated train split + the filtered other bucket + the excess `dev`/`test` speakers: Common Voice's official dev/test are balanced for benchmarking and far too large to hold out when fine-tuning a low-resource language, so they are capped (dev ~0.75h, test ~2.0h) by whole speakers and the remainder moved into train. Held-out dev/test stay disjoint from train by both speaker and sentence.

Each unvalidated other clip is CTC-decoded with `CoRal-project/roest-v2-wav2vec2-315m` and kept only if its character error rate vs the prompt is low (CER <= 0.25); 1607/2139 kept.

Columns

audio (16 kHz mono), text, lang (da), client_id (anonymized speaker), split, source (validated | other | moved-validated), quality_score.
