This article presents a review of the fluid dynamics, flow-structure interactions, and acoustics
associated with human phonation and speech. Our voice is produced through the process of …

As the primary means of communication, voice plays an important role in daily life. Voice
also conveys personal information such as social status, personal traits, and the emotional …

Voiced speech is a highly complex process involving coupled interactions between the
vocal fold structure, aerodynamics, and acoustic field. Reduced-order lumped-element …

The flow-induced responses of four self-oscillating synthetic vocal fold models are
compared. All models were life-sized and fabricated using flexible silicone compounds with …

Human vocal folds are highly deformable non-linear oscillators. During phonation, they
stretch up to 50% under the complex action of laryngeal muscles. Exploring the …

Sound for the human voice is produced via flow-induced vocal fold vibration. The vocal folds
consist of several layers of tissue, each with differing material properties 1. Normal voice …

In recent years, soft robotics technologies enabled the development of a new generation of
biomedical devices. The combination of elastomeric materials with tunable properties and …

The influence of asymmetric vocal fold stiffness on voice production was evaluated using life-
sized, self-oscillating vocal fold models with an idealized geometry based on the human …

A methodology for three-dimensionally printing ultrasoft silicone with a functional stiffness
gradient is presented. Ultraviolet-cure silicone was deposited via two independently …

Different source-related factors can lead to vocal fold instabilities and bifurcations referred to
as voice breaks. Nonlinear coupling in phonation suggests that changes in acoustic loading …
