What it does
Whisper is a well-known AI model from OpenAI that turns speech in audio into written text. faster-whisper is a rebuilt version that runs it on a quicker engine.
Its makers say it is up to four times faster than the original with the same accuracy, and uses less memory. It can be sped up further with a compression trick called quantization.
It works on ordinary processors and on NVIDIA graphics cards, and doesn't need a separate audio tool installed.
Who it's for
