Results

Whisper Medium accuracy and speed

Whisper Medium trades accuracy for a smaller download and less memory. On an older Mac it is often the largest Whisper that runs comfortably.

Method

How this was measured

Local results come from driving the real Superwhisper app over each clip, so they reflect the engine and decode settings that ship in the product rather than a separate implementation.

Word error rate counts insertions, deletions and substitutions against a human transcript, so lower is better. Speed is a multiple of real time, so higher is better. The full method and every other model is on the benchmarks page.
