Importance: Despite growing popularity in medicine, data on large language models in urogynecology are lacking.
Objective: The aim of this study was to compare the performance of ChatGPT-3.5, GPT-4, and Bard on the American Urogynecologic Society self-assessment examination.
Sound generation in human phonation and the underlying fluid-structure-acoustic interaction that describes the sound production mechanism are not fully understood. A previous experimental study, with a silicone made vocal fold model connected to a straight vocal tract pipe of fixed length, showed that vibroacoustic coupling can cause a deviation in the vocal fold vibration frequency. This occurred when the fundamental frequency of the vocal fold motion was close to the lowest acoustic resonance frequency of the pipe.

Article Synopsis
- Acoustic standing waves in the vocal tract affect both fluid flow through the glottis and vocal fold oscillation, impacting voice production.
- High-speed particle image velocimetry (PIV) was used to analyze the supraglottal flow field in a synthetic larynx, showing that vocal fold oscillation frequency aligns with vocal tract resonance frequencies, enhancing sound generation efficiency.
- The study found that this acoustic coupling improves vocal efficiency, increases voice quality, and allows for longer phonation while reducing the necessary glottal volume flow for stable vocal fold oscillation.
