Voice Activity Detection

Voice Activity Detection (VAD) is a technology that identifies when someone is speaking in an audio signal. It helps distinguish voices from background noise, making it useful in various applications like speech recognition, telecommunications, and hearing aids. By detecting speech segments, VAD improves performance and reduces processing time by ignoring silent or non-speech parts of audio. Essentially, it enables systems to focus only on relevant spoken content, enhancing communication clarity and efficiency in environments where sound is mixed with other noises.
