Let me build up my larynx muscles; maybe with microscopic weights?
There is more and more talk about vocal folds today, what used to be called vocal chords. These delicate tissues generate only an embryonic vibration though, which is not speech yet. This embryonic vibration is generated in the larynx and then it ultimately transformed into speech in the mouth by way to the phonetic process of forming vowels and consonants. Therefore, speech happens in the mouth, not the throat people.
Do you have to tell your eye how to adapt to light? No!
