Voice Activity Detection (VAD)
An algorithm that detects the presence or absence of human speech in an audio signal.
Voice Activity Detection (VAD) is a crucial pre-processing step for real-time transcription. Instead of sending continuous silence to the AI engine—which wastes CPU power and API costs—VAD intelligently slices the audio stream, activating the transcription engine only when someone is actually speaking. High-performance VAD, like the system powering CoScript, can differentiate between human speech, keyboard typing, breathing, and background noise, ensuring blazing-fast transcription with minimal resource drain.
