Voice activity detection (VAD)

Voice Activity Detection (VAD) is a process used in audio systems to determine when someone is speaking and when there is silence or background noise. It helps devices like phones or voice assistants focus on meaningful speech, reducing errors and saving processing power. VAD analyzes audio signals to identify patterns typical of human voice, enabling systems to activate only during speech and ignore non-speech sounds. This improves the clarity and efficiency of voice-related applications, ensuring they respond appropriately when someone is talking.
