Understanding how laryngeal anatomy shapes vocalization provides insights into this diversity, its mechanisms and their evolution. Rodents are ideal for exploring this variation because of their diverse mechanisms and vocal structures. Here, we describe the laryngeal morphology and sound production mechanisms underlying the vocalizations of Alston\u2019s singing mouse (Scotinomys teguina) and compare these results to those of other vocalizing mammals. We reconstructed the three-dimensional laryngeal morphology with micro-computed tomography, recorded laryngeal sound production using high-speed video and investigated frequency control using surgical ablations. We found that singing mice use a whistle mechanism that uniquely relies on the inflation of an enlarged air sac called the ventral pouch. Song frequency can be controlled by pouch volume, airflow and cricothyroid muscle action. Singing mouse laryngeal morphology and vocal mechanism are distinct from those of other Neotomids; singing mice appear to use inflation-mediated whistles for both distant and close exchanges. Inflatable air sacs have evolved repeatedly for sound modulation and filtering. Our results indicate a novel role for these structures in being required to generate sound. Together, our results expand on an emerging story of how biomechanic and morphological variation contributes to vocal diversity.<\/jats:p>","DOI":"10.1098\/rspb.2026.0153","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T00:07:41Z","timestamp":1778026061000},"source":"Crossref","is-referenced-by-count":0,"title":["Mechanisms and control of a novel vocalization: the singing mouse song is a whistle that depends on air sac inflation"],"prefix":"10.1098","volume":"293","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4491-1028","authenticated-orcid":false,"given":"Samantha Khouri","family":"Smith","sequence":"first","affiliation":[{"name":"The University of Texas at Austin 1 , , ,","place":["Austin, TX, USA"],"department":["Department of Integrative Biology"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonas","family":"H\u00e5kansson","sequence":"additional","affiliation":[{"name":"University of Southern Denmark 2 , , ,","place":["Odense, Region Syddanmark, Denmark"],"department":["Department of Biology"]},{"name":"University of Colorado Colorado Springs 3 , , ,","place":["Colorado Springs, CO, USA"],"department":["Department of Biology"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul W.","family":"Frazel","sequence":"additional","affiliation":[{"name":"New York University School of Medicine 4 , , ,","place":["New York, NY, USA"],"department":["Department of Neuroscience and Physiology"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Long","sequence":"additional","affiliation":[{"name":"New York University School of Medicine 4 , , ,","place":["New York, NY, USA"],"department":["Department of Neuroscience and Physiology"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6306-5715","authenticated-orcid":false,"given":"Coen P.
