HIGH, LOW Deprecated and inert: it no longer affects the call. It set how long the persona waited once the agent stopped talking, and measured across production simulations it moved the reply gap by less than the noise floor, because model and speech latency dominate it. Every persona now uses one voice-activity profile. Use interruption for a caller who talks over the agent. Still accepted and stored so existing clients keep working. BARGE_IN is stored as responseTiming: QUICK with interruption: OCCASIONAL.
RELAXED, NORMAL, QUICK, BARGE_IN How much the persona talks over the agent while it is still speaking. OFF waits its turn. BACKCHANNEL makes listening noises ("mm-hm") over the agent without taking the floor, which tests whether the agent wrongly stops for them. OCCASIONAL adds cutting in on some long agent turns, HEAVY on most of them. Timing is randomised per turn, so two runs of the same persona do not interrupt at identical moments.
