Here's what monkeys would sound like if they could talk

Princeton University: Monkeys known as macaques possess the vocal anatomy to produce “clearly intelligible” human speech but lack the brain circuitry to do so, according to new research. The findings — which could apply to other African and Asian primates known as Old World monkeys — suggest that human speech stems mainly from the unique evolution and construction of our brains, and is not linked to vocalization-related anatomical differences between humans and primates.
