AI Transcription Engine
Rev's AI transcription converts audio and video files to text at $0.25 per minute with turnaround in minutes, not hours. The engine supports 37 languages on the Pro plan (English and Spanish on Essentials, English only on Free). Accuracy sits around 90–95% for clean, single-speaker audio in English. Speaker diarization is included — the AI attempts to identify and label different speakers in your recording. The reality check: accuracy drops noticeably with multiple speakers, cross-talk, accents, and background noise. Speaker labels get confused in conversations where voices sound similar. For podcast interviews with two clear speakers in a quiet room, the AI does well. For a roundtable discussion with four people talking over each other, expect to spend time correcting the transcript. The built-in editor lets you play back audio while fixing errors, which helps, but it's still manual work.
