Sub too talkative? Use VoiceLock! VoiceLock uses reactive electrostimulation and a complex sensor arrow to detect minute throat muscle movements and respond with controlled electrical pulses, rendering the sub effectively mute. We see it here deployed on two subjects, one blue pegasus and one blue fox. With a simple app-based command we see the collars active, painlessly preventing the subs from speaking. Now much quieter they find themselves enjoying their owner's lap a lot more, nuzzling against their owner's hands and panting, unable and unwanting to say anything in objection~
