Why You Need to Pitch Your Voice Lower

The bad news: Stress makes your voice go higher. But you can fight it.

Back in the mid- or early '90s, I was videotaped for the first time, doing some media work for my then-employer, Princeton University. Aside from the usual reactions—I didn’t like my hair, my clothes, my physique, or what I did with my hands—I was most astonished by the shrill, pipsqueak voice that came trilling out of what I thought was my body.

I barely recognized it. It sounded ridiculous. And I couldn’t figure out what had happened. The voice didn’t sound anything like what I remembered from the day of taping. Was it a tech issue? Had my voice been distorted by a malicious camera operator? What was going on?

So I asked the other folks present that day if the silly voice on the recording sounded at all like my “real” voice. “Oh, sure,” they said, “pretty much. Maybe a little higher, and more stressed out, but pretty much.”

I learned three lessons from this exercise in humiliation.

First, your voice doesn’t sound to you like it does to other people. Quite simply, you’re hearing it from an internal perspective; they’re hearing it from outside. If you’re planning on doing any amount of public speaking, or if you simply want to know what you sound like to others, record your voice early on, get used to it, and start to work on it to make it better.

Second, adrenaline makes your voice go higher. When you’re stressed, your vocal cords tighten up and your pitch accordingly raises. Unless you’re completely cool for an event or important conversation, then, you need to practice deliberately lowering your pitch to compensate.

Third, we humans are incredibly good at hearing the stress in other people’s voices. We pick up on it immediately. That’s part of why public speakers need to learn to compensate. But there’s more. It turns out, according to recent research, that people speak in higher-pitched voices when talking to higher status people, or if we’re intimidated. So if you don’t want to signal either of these two impressions, lower your voice.

Another study found that men lower their voices in order to try to dominate in certain settings. In short, we signal dominance with lower-pitched voices. And still another study found that people who spoke with lowered voices were perceived as both more prestigious and more admirable.

Now you have the bad news. Stress, of the kind that you naturally experience when giving a presentation or having a crucial conversation, will tighten up your vocal cords, raise your pitch, and generally make you sound stressed out.

But that voice will also make you appear less prestigious, less admirable, and lower in status.

None of those things will help you succeed, so now’s the time to begin to work on your voice, keeping it low despite any stress you may be experiencing.

Relaxation exercises, and of course deep, belly breathing, will help you sound like the authority you are hoping to be, not like the terror-stricken underling I must have appeared back in the day for those TV appearances.

Live and learn!
