Technology Overview
Smarter Voice Detection for Any Environment
QHR’s VAD and MLVAD ensure crystal-clear communication by capturing only human speech while eliminating background noise. Integrated with Intelligent VOX, our headsets enable seamless, hands-free operation in any environment.
Voice Activity Detection (VAD)
Voice Activity Detection (VAD) relies on digital signal processing techniques, such as energy thresholding, spectral subtraction, and band-based amplitude analysis to detect the presence of speech in an audio stream. It works best in stable environments by comparing incoming audio against a reference background profile, identifying speech onset.

Machine Learning Voice Activity Detection (MLVAD)
Machine Learning Voice Activity Detection (MLVAD) employs a neural network that learns to distinguish human speech by modeling both short and long-term acoustic patterns, including formant transitions and spectral energy distributions.
Headset Type
MLVAD
Intelligent VOX
We integrate VAD and MLVAD into Intelligent VOX, ensuring only real speech triggers transmission. With configurable routing, it enables hands-free operation without false positives, even in loud environments.
