Silicone vocal fold models with tunable mechanical properties are fabricated using a mold-based method. Finite Element Method (FEM) simulations reveal altered resonance patterns caused by sulcus pathology, particularly within the frequency range of 100–140 Hz. An experimental phonation setup employing chopper-modulated airflow and stroboscopic imaging captures the vibratory responses. Initial tests conducted with 15 kPa silicone confirm alterations in resonance modes, demonstrating the system’s potential for analyzing vocal fold disorders. ©2025 IEEE.eninfo:eu-repo/semantics/closedAccessNon-Invasive TechniquePhonation SetupStroboscopic ImagingSulcus VocalisVocal Fold PhantomConference Paper2-s2.0-10501543663910.1109/BMEICON66226.2025.11113676N/A
