VAD Algorithms

Voice Activity Detection (VAD) algorithms identify when someone is speaking in an audio signal. They analyze sound patterns to distinguish speech from background noise or silence. By examining features like energy levels and frequency components, VAD algorithms decide if speech is present at any moment. This helps improve applications like voice recognition, telecommunication, and noise reduction by focusing only on relevant speech parts, making conversations clearer and systems more efficient. Essentially, VAD acts as a smart filter that recognizes and isolates speech signals in noisy environments.
