Chuvash Audio Dataset (Unlabeled)

This dataset consists of raw, unlabeled audio recordings primarily in the Chuvash language. It is intended for self-supervised learning, pre-training automatic speech recognition (ASR) models, or audio analysis tasks.

Note: While the primary language is Chuvash, some recordings may contain segments of Russian speech or code-switching, reflecting the bilingual nature of the region.
