+For the benchmark, we report RTF averaged over a 10 minute audio sample that is chunked into 30 second segments, mimicking the [chunked long-form transcription strategy](https://huggingface.co/blog/asr-chunking) performed in Transfomrmers. We measure RTF on an A100 80GB GPU (Driver Version: 535.54.03, CUDA Version: 12.2), performing 5 warm-up runs and 3 graded runs, over which the RTF is averaged to get the final result.
