Question

A small boy and a grown woman both speak at approximately the same pitch. Nonetheless, it’s easy to tell which is which from listening to the sounds of their voices. How are you able to make this determination?

Answer 1

Answer: Different vocal tract and harmonics

Explanation:

We are given that a small boy and a grown woman both speak at approximately the same pitch.

To distinguish between the two, we check their harmonics which is different for both of them owing to the different vocal tracts they have. Owing to different vocal tracts, they each produce different harmonic which is actually the multiple of frequency of the wave. Thus, we can make the determination using this.
