PreVox™ VAD is a robust voice activity detection module for digital voice communication systems. It reliably distinguishes speech from silence and background noise without any need for noise-specific tuning. Typically used inside vocoders, it can also operate as a standalone module, ensuring efficient use of channel and processing resources in any environment.

Key Features

• Reliable detection of speech activity in the presence of stationary and non-stationary noise
• Operates without noise-specific configuration
• Very low false-alarm rate with high sensitivity to speech
• Can be embedded into parametric vocoders or used as a standalone component
• Seamless integration with other PreVox™ modules (Neural RT, AGC, echo cancellation)

Applications

• Digital HF Radio
• Digital Mobile Radio (DMR)
• VoIP and other professional voice communication systems
