The evolution of speech: vision, rhythm, cooperation by Ghazanfar, Asif A, Takahashi, Daniel Y

“…Highlights • Human speech is multisensory, rhythmic, and cooperative in nature. • Similarly to humans, monkeys benefit from integrating faces and voices. • The…”

Internal states and extrinsic factors both determine monkey vocal production by Liao, Diana A., Zhang, Yisi S., Cai, Lili X., Ghazanfar, Asif A.

“…A key question for understanding speech evolution is whether or not the vocalizations of our closest living relatives—nonhuman primates—represent the…”

Cineradiography of Monkey Lip-Smacking Reveals Putative Precursors of Speech Dynamics by Ghazanfar, Asif A., Takahashi, Daniel Y., Mathur, Neil, Fitch, W. Tecumseh

“…A key feature of speech is its stereotypical 5 Hz rhythm [1, 2]. One theory posits that this rhythm evolved through the modification of rhythmic facial…”

Monkey vocal tracts are speech-ready by Fitch, W Tecumseh, de Boer, Bart, Mathur, Neil, Ghazanfar, Asif A

“…For four decades, the inability of nonhuman primates to produce human speech sounds has been claimed to stem from limitations in their vocal tract anatomy, a…”

Facial expressions and the evolution of the speech rhythm by Ghazanfar, Asif A, Takahashi, Daniel Y

“…In primates, different vocalizations are produced, at least in part, by making different facial expressions. Not surprisingly, humans, apes, and monkeys all…”

Cooperative vocal control in marmoset monkeys via vocal feedback by Choi, Jung Yoon, Takahashi, Daniel Y, Ghazanfar, Asif A

“…Humans adjust speech amplitude as a function of distance from a listener; we do so in a manner that would compensate for such distance. This ability is…”

Interactions between the Superior Temporal Sulcus and Auditory Cortex Mediate Dynamic Face/Voice Integration in Rhesus Monkeys by Ghazanfar, Asif A, Chandrasekaran, Chandramouli, Logothetis, Nikos K

“…The existence of multiple nodes in the cortical network that integrate faces and voices suggests that they may be interacting and influencing each other during…”
