Résumé
It balances false accepts, false rejects, latency, and power.
Plongeur bu xóot
Wake-word detection is a form of keyword spotting. A cascade can use a low-power detector before a more expensive recognizer or assistant pipeline. Hello Edge studies small-footprint keyword spotting under microcontroller constraints. Google research describes contextual speech recognition for trigger phrase detection. A confidence threshold over frames can reduce accidental activations but may increase missed triggers or latency. Hello Edge compares several keyword-spotting architectures on Google Speech Commands under microcontroller resource constraints. Its depthwise separable CNN reports 95.4% accuracy, about 10% higher than a DNN with a similar parameter count in that evaluation. Results are not universal device or language guarantees. A confidence threshold over frames can reduce accidental activations but may increase missed triggers or latency; assess false-accept and false-reject rates in realistic audio.
Doxal ci àdduna dëgg
Run an always-on detector locally and trigger a second-stage recognizer.
Measure false accepts and false rejects on representative audio.
Use acoustic features such as log-mel spectrograms as model input.
Test robustness to noise, accents, and background speech.
Ëlëgu Keyword Spotting ak Wake Words
Wake-word models continue to improve with distillation and hardware-aware design. Evaluate false-accept and false-reject rates in realistic acoustic conditions and set user controls for microphones and activation.

What trade-off can raising a wake-word detector’s activation threshold create?
A higher threshold can reduce false activations, but may miss quieter or variable pronunciations or require more evidence. Measure false-accept and false-reject rates under realistic conditions.
