John Hansen
Also known as John H. L. Hansen, John H.L. Hansen
John Hansen researches speech recognition for stressed and noisy speech, using machine-learning concepts. He earned electrical engineering degrees at Rutgers and Georgia Tech, began his academic career at Duke in 1988, moved to Colorado in 1999, and joined UT Dallas in 2005 to establish the Center for Robust Speech Systems. His 1995 study analyzed speech under stress and noise, and his 2025 child speech recognition study discussed DNN-HMM, transformer, and discrete speech-unit systems. ISCA named him a Fellow in 2010 and selected him for its Medal for Scientific Achievement in 2026. As of October 2026, he is associate dean for research, professor of electrical and computer engineering, and Distinguished University Chair in Telecommunications Engineering at UT Dallas.
