It happens to almost everyone. You listen back to a voicemail, a video from a family party, or an old cassette tape, and you wince. Is that really what you sound like? It seems higher, thinner, and just not quite right.
Here's the reassuring answer: the recording is closer to what other people hear. When you talk, you hear your voice two ways at once, through the air and through the bones of your own head. Your skull carries lower sounds especially well, so to yourself your voice sounds deeper and fuller than it does to anyone else. A recording strips that extra bass away.
Two Paths to Your Ears
When someone else speaks, their voice reaches you only one way. Sound waves travel through the air and hit your eardrums. But when you speak, the vibrations from your vocal cords also travel through your body, straight to your inner ears. Scientists call this bone conduction.
One throat specialist, laryngologist Martin Birchall, described hearing your own voice while talking as hearing it through a cave complex inside your own head. The sound bounces through your sinuses and the hollow spaces of your skull before you hear it. That blend of inside and outside sound has a different quality than the outside sound alone.
Because the skull carries low frequencies better than air does, people perceive their own voices as lower and richer than others do. So when you hear a recording, it frequently sounds higher than you expect.
It's Not Just the Sound
Psychologists even have a name for disliking your recorded voice: voice confrontation. And it turns out the audio difference is only part of the story.
In 1966, researchers Philip Holzman and Clyde Rousey concluded that recordings also reveal little clues people don't notice in themselves while talking. These include hints of nervousness, indecision, sadness, or irritation. Hearing those cues from the outside can be uncomfortable.
There's a telling twist. In a 2013 study, people rated their own voices much more favorably when they didn't realize the voice was theirs. In other words, a lot of the cringe comes from knowing it's you.
We Barely Recognize Ourselves
Since we build our sense of our own voice around what we hear inside our heads, a recording can be surprisingly unfamiliar. In a 1967 study, only 38 percent of people were able to identify recordings of their own voice within five seconds.
Another study found that people who learned a second language after age 16 felt more uncomfortable hearing recordings of themselves in their first language than in their second. Our relationship with our own voice is more complicated than it seems.
Bone Conduction Has Other Uses
The same trick that changes how you hear yourself has been put to clever use for centuries. The first bone conduction hearing aids date back to the 1500s, when Italian physician Girolamo Cardano noticed that a person with hearing loss could hear music through a rod held between the teeth and touching an instrument.
Ludwig van Beethoven is said to have used a similar idea as his hearing failed, resting one end of a rod on his piano and holding the other in his mouth. Some musicians still put the stem of a vibrating tuning fork between their back teeth so they can hear the note while both hands tune their instrument.
So the next time you cringe at a recording, go easy on yourself. That voice sounds strange only to you. To your friends and family, it's simply the voice they know and love, and it always has been.
