In this video I cover Whisper, an ASR system from OpenAI's "Robust Speech Recognition via Large-Scale Weak Supervision" paper.

Trained on a huge multi-lingual, multi-task weakly supervised dataset it achieves a very high effective robustness and accuracy closing the gap with the human baseline using only an off-the-shelf transformer.

I walk you through both the paper as well as the actual code. Let me know whether the code part helped!
