MUSCAT — Merged Long-Form Samples
This dataset is a merged, long-form reformatting of
goodpiku/muscat-eval
(MUSCAT: A Multi-Device Dataset for Code-Switching ASR and Segmentation
Evaluation).
The original MUSCAT release stores each conversation as many short,
single-language segments. Here those segments are concatenated back into one
continuous recording per conversation, so each row is a single long-form
code-switching audio with inline language/timing markers. The layout… See the full description on the dataset page: https://huggingface.co/datasets/BrunoHays/muscat-merged-samples.personaplex-finetuning-pharma-data-sample
