Edit ProfileCareer
He is also a professor in residence (emeritus) of electrical engineering and computer science at the University of California, Berkeley. He founded ICSI"s Realization Group, which later become known as the Speech Group, in 1988. He served as director of ICSI from 1999 through 2011.
He is the co-inventor of the Relative Spectral (RASTA) approach to speech signal processing, first described in a technical report published in 1991.
In 1993, Morgan and Herve Bourlard published their work on the hybrid system approach to speech recognition, which uses neural networks probabilistically with Hidden Markov Models (HMMS). The system improved automatic speech recognition techniques based on HMMs by providing discriminative training, incorporating multiple input sources, and using a flexible architecture able to accommodate contextual inputs and feedbacks.
The work has been described as "seminal.". Morgan was the principal investigator of the IARPA-funded project Outing Unfortunate Characteristics of HMMs, which sought to identify problems in automatic speech recognition technology.
He has more than 200 publications, including three books, He is a fellow of the Institute of Electrical and Electronics Engineers and the International Speech Communication Association.
He is on the editorial board of Speech Communication Magazine, of which he is a former co-editor-in-chief
