Speech to Text AI Model & Provider Leaderboard
Analysis and comparison of Speech to Text transcription models & API providers. Artificial Analysis has analyzed speech to text models and hosting providers across different characteristics including their word error rate (lower is better), speed and price. Speed is represented by 'Speed Factor' which is the number of audio seconds transcribed per second (higher is better). For further details, see our methodology page.
