What is real time transcription?
Real time transcription is the live conversion of speech into readable, searchable text as you speak. Instead of waiting minutes or hours for batch processing, Story321 streams partial and final results continuously, so captions and notes are always up to the moment. This unlocks instant accessibility, faster decisions, and richer engagement during meetings, webinars, broadcasts, and support calls. Our approach uses advanced speech recognition models, dynamic noise handling, and smart punctuation to deliver dependable, real time transcription for global teams. For developers, our WebSocket and REST endpoints make it easy to integrate real time transcription into any app, while our dashboards help non-technical users start transcribing in seconds.
