Here is the transcript and summary of voice expert Rébecca Kleinberger’s talk titled “Why You Don’t Like The Sound Of Your Own Voice” at TED conference. In this talk, Rébecca Kleinberger, a researcher at MIT Media Lab, explores the complex relationship people have with their own voices. She highlights the connection between the evolution of humans and the growth of our voice box, emphasizing the importance of the voice in communication and creating bonds. Kleinberger also discusses how our voice is linked to our relationships and personal experiences, exploring the concept of the “mask” and the different voices we possess.
Listen to the audio version here:
If you ask evolutionary biologists when did humans became humans, some of them will say that at some point we started standing on our feet, became biped, and became the masters of our environment. Others will say that it’s because our brains started growing much bigger that we’re able to have much more complex cognitive processes. And others might argue that it’s because we developed a language that allowed us to evolve as a species.
DESCENT OF THE LARYNX
Interestingly, those three phenomena are all connected. We’re not sure how or in which order, but they are all linked with the change of shape of a little bone in the back of your neck that changed the angle between our head and our body that made us able to stand upright, but also for our brain to evolve in the back, and for our voice box to grow from 7 centimeters for primates to 11 and up to 17 centimeters for humans. And this is called the descent of the larynx, and the larynx is the site of your voice.
