OpenAI Whisper: Robust Speech Recognition via Large-Scale Weak Supervision | Paper and Code
❤️ Become The AI Epiphany Patreon ❤️ https://www.patreon.com/theaiepiphany 👨👩👧👦 Join our Discord community 👨👩👧👦 https://discord.gg/peBrCpheKE 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! ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ✅ Paper: https://cdn.openai.com/papers/whisper.pdf ✅ Code: https://github.com/openai/whisper ✅ Nice explanation of mel spectrograms: https://www.youtube.com/watch?v=9GHCiiDLHQ4 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⌚️ Timetable: 00:00:00 Intro 00:02:05 Paper overview 00:07:30 Collecting a large scale weakly supervised dataset 00:13:55 Evaluation metric issues (WER) 00:16:05 Effective robustness 00:18:40 Scaling laws in progress 00:26:30 Decoding is hacky 00:28:30 Code walk-through 00:30:25 Model architecture (diagram vs code) 00:33:30 Transcription task 00:34:10 Loading the audio, mel spectrograms 00:37:50 Language detection 00:45:00 Transcription task continued 00:47:35 Suppressing token logits 00:52:00 Voice activity detection 00:53:35 Decoding and heuristics 01:01:56 Outro ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 💰 BECOME A PATREON OF THE AI EPIPHANY ❤️ If these videos, GitHub projects, and blogs help you, consider helping me out by supporting me on Patreon!
