Even if it’s not the same, it may still be close enough. How can we know what to do with the vocal chords in order to reproduce the sound?

How do you know how to operate the muscles in your arm and hand to bring your hand and fingers to just the right point in space, and apply the right amount of force, to catch a ball that is hurtling towards you?

Muscle control is a learned skill, and controlling the muscles in your limbs is fundamentally no different from controlling the tension in your vocal cords. The neurons in your central and peripheral nervous system have the ability to “tune” themselves through trial and error, so that over time they learn to accurately map a conscious or unconscious intention by their “master” to an accurate motor output. For your limb muscles, this means e.g. moving parts of your body to a certain point in space, grasping objects, etc. For your vocal cords it means generating a certain sound.
