### Dataset Summary
This dataset is a modified version of the [LibriSpeech](http://www.openslr.org/12) corpus, converted into parquet format to enhance I/O efficiency in high-performance computing environments. LibriSpeech is widely used for speech recognition research and includes over 1,000 hours of English read speech. This modification retains the original data attributes while improving data handling for distributed training on large-scale models.
