Chuvash Audio Dataset (Unlabeled)
This dataset consists of raw, unlabeled audio recordings primarily in the Chuvash language. It is aggregated from various sources including audiobooks, religious texts, and lyrical content. 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.
