Why Your Recorded Voice Sounds Like a Stranger
Most people cringe the first time they hear a recording of their own voice. It sounds higher, thinner, and somehow less pleasant than the voice they believe they have. The explanation is not that the recording is wrong. It is that you normally hear yourself in a different way from everyone else.
When another person talks to you, the sound reaches your ears through the air. The sound waves make your eardrums vibrate, and the vibrations travel to the inner ear, where nerves send signals to the brain. When you talk, that same path carries your voice too. But your voice also starts in your throat, so vibrations spread through the bones and soft tissue of your head and reach the inner ear directly.
Sound that travels through bone tends to boost the deeper, lower tones. Because you hear a blend of air sound and bone sound, your own voice seems fuller and richer to you. A microphone picks up only the sound that moves through the air, which is the version your friends and family hear.
So the recording is a fairly honest picture of how other people hear you. With practice, most people get used to it. Actors, singers, and radio hosts listen to themselves often, because it helps them improve the way they speak.
