YDS

YDS is a filtered Uzbek speech and transcript dataset. This release contains 196,412 clips (240.62 hours). It is public and requires manual approval for access.

Data

Each row has embedded mono FLAC audio, an Uzbek transcript, word-level CTC timings in JSON, duration, sample rate, alignment score, speaker overlap, and source recording/time identifiers. There is one uz configuration and one train split. Speaker labels across clips are not established identities.

Load with the Hugging Face datasets library using load_dataset("instinct1912/yds", "uz", split="train").

Processing and quality filters

Source segments were restored on a GPU pod, transcribed in Uzbek with Gemini 3.8 Flash, and accepted only when intelligible. One accepted transcription per clip was retained. Accepted text was CTC-aligned to audio; clips with failed alignment or audio/text checks were excluded. Pyannote diarization then retained clips assessed as one speaker with no more than 0.10 seconds of overlapping speech. Passing clips were trimmed around the first and last aligned words with up to 120 ms before and 180 ms after, then checked again for duration, silence, clipping, peak, and non-finite samples. This dataset's final check permits edge silence because source segments were VAD processed.

Of 198,255 speaker-passed clips, 196,412 passed final trim and audio QA; 1,843 were excluded. Automated checks reduce errors but do not guarantee every transcription or speaker assignment is correct. Recordings may contain background noise and varied recording conditions. No evaluation split has been curated.
