I'm curious which of the Whisper derivatives is actually the fastest ?
Since faster-whisper claims 4x speedup over base Whisper, and I've found WhisperX to be faster still (for longer audio where it can do batch inference), at least on consumer GPUs.
So with AiOla saying "50% speedup", is that actually noteworthy?
- gronky_ 2y agoFrom my understanding faster-whisper optimizes the inference without changing the model itself. Here they seem to be changing the model architecture but not applying other optimizations. 50% on its own doesn’t make this the current best choice for production. But I imagine this could become the new base model that all of the inference optimizations are applied to. Wonder if it’s plug and play or if faster-whisper and others would need to reimplement from scratch?
- dloss 2y agoIs this even faster? https://github.com/Vaibhavs10/insanely-fast-whisper https://github.com/Vaibhavs10/insanely-fast-whisper If so, is the quality still acceptable?
- tomp 2y agoDepends what you mean by “fast”. I’ve tested WhisperLive, it’s basically real-time (i.e. low latency).
- gunalx 2y agoDosent whisperlive just use faster-whisper under the hood. Witch can be way faster than real time.
- tomp 2y agoThere's a difference between speed & latency when it comes to performance. Faster-whisper can process audio faster than real-time, but AFAIK vanilla Whisper needs a few seconds long audio "frame" to do inference/STT. Whisper Live fixes that, and reduces latency to a few tens/hundreds of ms.
- gcr 2y agoWhat sort of performance are you needing? My Apple M1 MacBook (2021) can infer whisper-medium at roughly 10x realtime, for comparison. Takes about 20min to process three hours of audio.
