About

Vistiqa is a medical technology (medtech) company that uses Voice CFD to simulate how the human larynx produces voice.

Voice CFD (computational fluid dynamics) uses computer models of fluid flow to study how air moves through the larynx and becomes voice. It shows laryngeal airflow, vocal-fold motion, and sound in detail.

Our goal is a validated pipeline from laryngeal simulation to a patient-specific vocal-fold implant.

Simulation workflow for modeling human phonation.

Simulations

We use high-fidelity CFD to simulate how air, tissue, and sound interact in the larynx, and how those interactions shape the voice.

Key topics

Vocal-fold oscillation
Glottal jet and laryngeal turbulence
Flow-induced voice sound

Core expertise

Large-eddy simulation (LES)
Computational aeroacoustics (CAA)
Fluid-structure-acoustic interaction (FSAI)
Surrogate modeling
Uncertainty quantification (UQ)
