Here, a 6 year old female Japanese macaque was trained to phonate under an operant conditioning paradigm. The resulting \u201ccoo\u201d calls, and spontaneously uttered \u201cgrowl\u201d and \u201cchirp\u201d calls, were recorded with sound pressure level (SPL) calibrated microphones and electroglottography (EGG), a non-invasive method for assessing the dynamics of phonation. A total of 448 calls were recorded, complemented by ex vivo recordings on an excised Japanese macaque larynx. In this novel multidimensional investigative paradigm, in vivo and ex vivo data were matched via comparable EGG waveforms. Subsequent analysis suggests that the vocal range (range of fundamental frequency and SPL) was comparable to that of a 7-10 year old human, with the exception of low-intensity chirps, whose production may be facilitated by the species' vocal membranes. In coo calls, redundant control of fundamental frequency in relation to SPL was also comparable to humans. EGG data revealed that growls, coos, and chirps were produced by distinct laryngeal vibratory mechanisms. EGG further suggested changes in the degree of vocal fold adduction in vivo, resulting in spectral variation within the emitted coo calls, ranging from \u201cbreathy\u201d (including aerodynamic noise components) to \u201cnon-breathy\u201d. This is again analogous to humans, corroborating the notion that phonation in humans and non-human primates is based on universal physical and physiological principles.<\/jats:p>","DOI":"10.1242\/jeb.171801","type":"journal-article","created":{"date-parts":[[2018,4,3]],"date-time":"2018-04-03T13:57:18Z","timestamp":1522763838000},"source":"Crossref","is-referenced-by-count":3,"title":["Japanese macaque phonatory physiology"],"prefix":"10.1242","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9095-3953","authenticated-orcid":false,"given":"Christian T.","family":"Herbst","sequence":"first","affiliation":[{"name":"Bioacoustics Laboratory, Department of Cognitive Biology, University Vienna, Althanstrasse 14, 1090 Wien, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Koda","sequence":"additional","affiliation":[{"name":"Primate Research Institute, Kyoto University, Inuyama, Aichi 484-8506, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takumi","family":"Kunieda","sequence":"additional","affiliation":[{"name":"Primate Research Institute, Kyoto University, Inuyama, Aichi 484-8506, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juri","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Primate Research Institute, Kyoto University, Inuyama, Aichi 484-8506, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2014-7387","authenticated-orcid":false,"given":"Maxime","family":"Garcia","sequence":"additional","affiliation":[{"name":"Bioacoustics Laboratory, Department of Cognitive Biology, University Vienna, Althanstrasse 14, 1090 Wien, Austria"},{"name":"ENES Lab, Universit\u00e9 Lyon\/Saint-Etienne, NEURO-PSI, CNRS UMR 9197, 23 rue Dr. Paul Michelon, 42023 Saint-Etienne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.
