Modular Control of Speech

Modular Control of Speech

Project Overview 

The human body constructs separate subsystems, sometimes referred to as modules, that function as individual body-based devices. Each module is activated by a group of muscles trained to work together to achieve a specific task, such as smiling or lip closure. These independent modules can output low-level memorized routines that no longer require conscious control. They facilitate the execution of higher-level tasks that require intentional planning and explain how humans are able to control high-dimensional bodies with low-dimensional control systems. Human speech is a uniquely complex motor behaviour, making it an ideal area of research for investigating modular control in motor movement. This branch of research at ISRL seeks to provide insight into the control of speech movement and corresponding neural organization through investigating speech motor modules.
