[...] the child is exercising his organs of utterance and gaining conscious command of them, partly by a mere native impulse to the exertion of all his native powers, partly by imitation of the sound-making persons about him: the child brought up in solitude would be comparatively silent.
- Whitney (1875), a pag.10

Control and management of the organs of utterance comes much more slowly; but the time arrives when the child can imitate at least some of the audible as well as the visible acts of others […].

The organs by which alphabetic sounds are produced are the lungs, the larynx, and the parts of the mouth above the larynx.
- Whitney (1875), a pag.59

They [physicist and physiologist] […] have to do with the organs of utterance, which produce the audible vibration; with their obedience to the directions of the will: directions given but not executed under the review of consciousness, and implying that control of the mind over the muscular apparatus of the body which is by no means the least of mysteries.
- Whitney (1875), a pag.15

We may fairly say that, in the process of time, with greater acquired skill in the art of utterance, men’s organs have come to be able to make and use more nicely distinguished, more slightly shaded tones than at first. This is no mere loose poetic expression; nor, on the other hand, does it imply any organic change in the organs of utterance. The case is only as in any other department of effort: the higher skill is won by the advanced or adult speakers, and the shape which they give to their inherited speech becomes the norm toward which new learners have to strive, attaining it when they can.
