Audio-to-text conversion turns spoken words in a recording into written text. Automatic transcription gives you a draft to review and edit.
Unlike older speech recognition systems that required training for specific voices, today's AI transcription works out of the box with any speaker, accent, or dialect. The technology uses deep learning neural networks trained on hundreds of thousands of hours of multilingual audio data.
