Very controversial because there are no linguistic or speech. 1866: linguistic society of paris banned speculative articles about the origin of language. Most aspects of human vocal production are shared with other. Anatomy, acoustics, and central control of the vocal tract can be animals similar. Fitch both peripheral and central factors played a role in the appearance of speech. Central: central neural mechanisms (vocal control and imitation) The airflow through the vibrating vocal folds is the energy source. Vibration creates buzz-like sound, but no speech sounds are made.

Each configuration has a set of preferred frequencies called formants. Constrained space for the tongue that allows in-out movement only.
