Wake-Word Detector 2D: Score Ribbon & Power Dial Simulator

Every "Hey Siri" or "OK Google" moment starts with a tiny, always-on detector running a matched-filter correlation against a stored keyword template on a handful of milliwatts, long before any cloud or on-device speech recognizer wakes up. This 2D simulator streams a live strip-chart of analysis frames, scores each one with normalized cross-correlation, and lets you tune the detection threshold, background noise floor, how often the keyword is actually spoken, and the microphone's power-saving duty cycle. Drag the ribbon to scrub back through history, watch the chip-state indicator and power dial react in real time, and see true accepts, phantom false-accept wake-ups and missed false rejects accumulate — a faithful two-state power model of a real mobile voice-assistant chip.
