Gait Change in Tongue Movement

Here I present Bryan Gick's and my research on "Gait Change in Tongue Movement", published in Scientific Reports on Monday, August 16, 2021.

This article demonstrates how tongues can change gait from slow to fast speech in order to gain access to wider speech-rate ranges, much as people switch from walking to running.
