【 摘 要 】

In a series of works, different models have shed light on the acoustic properties of air sacs, an organ located in the laryngeal region that is present in all great apes with the exception of humans. These works have shown how the loss of air sacs expands the number of possible digits but not the amount of signals per se. The number of signals in human language increased when the codifying property known as duality of patterning became characteristic of the codifying system, allowing digits to be combined in order for new signals to be codified. A direct relationship between air sacs and duality is presently being plotted, integrating linguistic theory and data from computational models into an evolutionary and developmental perspective of the evolution of modern speech.
