Wake Word Detection with Edge AI

Always-on keyword spotting that listens for a specific activation phrase. Ultra-low-power operation is critical since the model runs continuously waiting for the trigger word. Uses DS-CNN or depthwise separable convolutions on mel-spectrograms of 1-second audio windows. The model classifies short audio segments as either the target keyword or background noise. Common in smart speakers, voice-activated appliances, and hands-free industrial interfaces.
