About 98% on clear audio. The figure comes from the Whisper large-v3 models Stenovo runs on, at about 2% word error rate on clean English speech; for comparison, controlled studies measure professional human transcribers at around 5% on conversational audio. Loud background noise, people talking over each other and poor microphones lower it, so the cleaner the recording, the better the text. See the Whisper benchmarks and the human-parity study.
