Professor Nelson Morgan is the former director of the International Computer Science Institute (ICSI), where he was also the Speech Group leader.[1] He is also a professor in residence (emeritus) of electrical engineering and computer science at the University of California, Berkeley.[2] He recently co-founded UpRise Campaigns, a California Social Purpose Corporation focused on campaign reform through empowering volunteerism.[3]

Morgan was born in 1949 and received his PhD as an NSF fellow from UC Berkeley in 1980.[4] 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.[5]

He is the co-inventor of the Relative Spectral (RASTA) approach to speech signal processing, first described in a technical report published in 1991.[6][7]

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).[8] 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.".[9] Morgan won the 1996 IEEE Signal Processing Magazine Best Paper Award for a paper with Bourlard.[10]

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.[11] He also led a team of universities to build speech recognition systems for low resource languages as part of the IARPA Babel program.[12]

He has more than 200 publications, including three books.,[13][14] He is a fellow of the IEEE[15] and the International Speech Communication Association.[16] He is on the editorial board of Speech Communication Magazine, of which he is a former co-editor-in-chief.[17]
