stt-sampler-v1

Licensing: clips inherit their source dataset's license — CC-BY-4.0 for MInDS-14 and FLEURS clips, CC-BY-NC-SA-4.0 for Speech-MASSIVE clips (source_dataset column identifies each clip's origin).

A small, balanced, representative multilingual ASR eval sampler for the OVOS Plugin Arena: 100 clips per language x 20 locales = 2000 clips, 16 kHz mono float32, one config per locale (load_dataset("OpenVoiceOS/stt-sampler-v1", "<lang>")). Designed to seed every STT leaderboard breadth-first; full-size datasets accrete over time.

Composition

Per locale: 100 clips, drawn 50/50 when two sources cover the locale, else 100 from the single source. Sampling is deterministic (fixed seed) and spread across each source split.

Arena integration

Fighter predictions for this corpus are published to OpenVoiceOS/ovos-stt-bench-stt-sampler-v1 as predictions/<lang>/<competitor_id>.jsonl rows (see the arena's docs/SPECIFICATION.md §3.2).
