How It Works
How It Works
VSI Transcription combines advanced AI and cloud-based processing to transform spoken words into accurate, real-time captions. Our system follows a proven five-step process — from capturing audio to delivering downloadable transcripts — ensuring accessibility and engagement for every audience.
Audio Input Captured
A live or recorded audio feed via VSI WebRTC Broadcaster, Phone, NDI, Encoder feed (vMix, OBS, Haivision, Cisco WebEx, MS Teams, Zoom, SIP Trunk) captures the audio in real-time, providing the foundation for accurate captioning and transcription.
Speech Recognition (ASR)
The audio is instantly processed by our AI-driven Automatic Speech Recognition engine. Glossaries and multilingual packs enhance recognition of industry terms, accents, and custom vocabulary.
Natural Language Processing (NLP)
NLP technology refines raw transcription by adding punctuation, recognizing speaker changes, and correcting contextual errors, ensuring text reads naturally and clearly.
Display to Users
Within milliseconds (<200ms), captions are displayed on event screens, conferencing platforms (Zoom, Teams, WebEx), live TV, or custom apps — complete with customizable fonts, colors, and backgrounds. Optional TTS (text to speech) of source audio along with AI-translated languages are also offered.
Post-Captioning & Transcripts
After the event, transcripts are cleaned, edited, and available for download in multiple formats (.srt, .vtt, .txt). The secure VSI dashboard makes it simple to access, edit, and share.
