[2] Morgan is the co-inventor of the Relative Spectral (RASTA) approach to speech signal processing, first described in a technical report published in 1991.
[5] Morgan worked at National Semiconductor before taking up the post as a professor in residence at University of California, Berkeley.
[6] 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).
"[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.
