Monkeys Could Speak, If They Were Wired For It | The Daily Grail: A new paper submitted to Science Advances shows the pendulum swinging back in the other direction. Researchers at Princeton University and the University of Vienna have proven monkey vocal tracts are speech-ready. Rather than using a cadaver, William Tecumseh Fitch and Asif Ghazanfar taught a macaque to sit in a chair while they took x-ray videos of the monkey's throat. Once they had enough footage showing most configurations of their vocal tract, the data was plugged into a program capable of simulating speech with surprising results.

Never any doubt animals certainly communicate. Of course they do; among themselves. But with us humans as well. That is not the question. The issue is speech that is the same as us humans.
