Voice-Trigger Detection: Minimizing Misses Under a False-Alarm Constraint
For a voice-trigger detector, first require the false-alarm frequency to stay below a chosen limit. Among detectors that satisfy that constraint, minimize the false-negative rate—the proportion of spoken trigger phrases the detector misses. Thus, false-alarm frequency is the satisficing metric, while false-negative rate is the optimizing metric.
