What Should Your Company's AI Sound Like to Customers?

As AI voice systems move toward handling 70-80% of customer service interactions by 2028-2029, most organizations have no framework for calibrating how confident their AI sounds relative to what it actually knows. Research in vocal psychology shows confident delivery increases persuasiveness and triggers authority deference independent of information quality, meaning a moderately certain AI recommendation can be heard as definitive when spoken aloud. The fix requires institutional governance that classifies interactions by risk and assigns vocal delivery rules accordingly, paired with real-time systems that adjust tone based on model confidence and user context.
