Vanessa Van Edwards explains how vocal inflection and pitch shape others' perceptions: higher pitch signals approachability (as in baby talk), lower pitch signals seriousness and confidence, and uptalk/question-inflection undermines authority. She gives practical examples—introductions and stating prices—showing that firm, downward inflection communicates confidence and prevents negotiation. The excerpt is an instructional segment from a YouTube video.

You said inflection matters, which is why people, when they're talking to babies, raise their voice and say, oh, you look so cute today. Okay, so the higher voice. The higher pitch means I'm approachable. I can do this. But when we're down here, we're nice and low. It means we're taking seriously the issue is the uptalk or the question inflection. So if I were to come on and say, hi, my name is Vanessa. I'm happy to be here. Let's talk about cues. It's actually giving away my vocal power, but that doesn't show confidence. So what if I say, hi, my name is Nate. I'm happy to be here. That's it. That's it. Because salespeople, like, if you ever mention a number and you say my cost is $5,000, you're telling someone, negotiate with me. I don't. It's $5,000.
