Acoustic simulation of sound propagation inside the vocal tract is a key element of speech
research, especially for articulatory synthesis, which allows one to relate the physics of …

The synthesis of diphthongs in three-dimensions (3D) involves the simulation of acoustic
waves propagating through a complex 3D vocal tract geometry that deforms over time …

In recent years, more and more people suffer from voice-related diseases. Given the
limitations of current pathological speech conversion methods, that is, a method can only …

Individuals, such as voice-related professionals, elderly people and smokers, are
increasingly suffering from voice disorder, which implies the importance of pathological …

A link is established between biomechanical and acoustic 3D models for the numerical
simulation of vowel‐vowel utterances. The former rely on the activation and contraction of …

Articulatory speech synthesis has the potential to offer more natural sounding synthetic
speech than established concatenative or parametric synthesis methods. Time-domain …

The piriform fossae are two small side branches of the vocal tract that are located close to
the larynx. They act as quarter wave resonators and introduce two deep dips around 5 kHz …

The numerical simulation of sibilant sounds in three‐dimensional realistic vocal tracts
constitutes a challenging problem because it involves a wide range of turbulent flow scales …

The finite-difference time-domain (FDTD) method has been widely used for vocal tract
acoustic modelling due to its simplicity and low computational cost. Nevertheless, the …

Objective Speech signal processing has become an important technique to ensure that the
voice interaction system communicates accurately with the user by improving the clarity or …
