ABSTRACT: Speech technology has quietly become a pervasive influence in our daily lives despite widespread concerns about research progress over the past 20 years. However, because language is so fundamental to our human existence, the expectations users have for human computer collaboration have continually outpaced research advances. In this talk, we will review recent research on fundamentally new approaches to speech recognition with an emphasis on machine learning and discrimination. We will then project future research directions in this field based on a historical perspective of progress over the past 50 years. We will conclude with a discussion of why research in this area will have a fundamental impact on computational science far beyond speech or language.
BIOGRAPHY: Joseph Picone is currently a Professor in the Department of Electrical and Computer Engineering at Mississippi State University, where he also directs the Intelligent Electronic Systems program at the Center for Advanced Vehicular Systems. His principal research interests are the development of new statistical modeling techniques for speech recognition. He has previously been employed by Texas Instruments and AT&T Bell Laboratories. Dr. Picone received his Ph.D. in Electrical Engineering from Illinois Institute of Technology in 1983. He is a Senior Member of the IEEE.
“Language is the preeminent trait of the human species.”
“I never met someone who wasn’t interested in language.”
“I decided to work on language because it seemed to be the hardest problem to solve.”
Integrate speech recognition, prosody and parsing on conversational speech
“Though linear statistical models have dominated the literature for the past 100 years, they have yet to explain simple physical phenomena.”

A priori expert knowledge created a generation of highly constrained systems (e.g. isolated word recognition, parsing of written text, fixed-font OCR).
… but that isn’t the end of the story …
