How much lag will ruin call performance? What if your bot is too fast for its own good? We'll explore how latency doesn’t just affect performance, it affects perception. I conducted an experiment with five versions of the same voice bot, each with different response latencies, to see how users felt about the interaction. Dive into the subtle science of seeming thoughtful: how do milliseconds influence trust, comfort, and believability in voice AI? You’ll leave with a new understanding of how timing is more than a metric, it’s part of your bot’s personality.
