The Tamil Time-Aligned Speech Dataset is a curated 5-hour speech corpus consisting of Tamil audio recordings paired with precise time-aligned transcriptions. The dataset is designed to support a wide range of speech and language technology tasks, including automatic speech recognition, forced alignment, speech segmentation, subtitle generation, and timestamp-aware linguistic analysis. By preserving the correspondence between spoken audio and textual content at the segment level, the dataset enables detailed study of pronunciation, timing, and spoken language structure. It is a useful resource for researchers, developers, and institutions working on Tamil speech technologies and low-resource language processing.
