More than a quarter century ago, I introduced the term and the concept of spoken language processing. Spoken language is our primary medium of communication in which the ultimate source is the speakers mind and the destination is the listeners mind. Unlike written language, it is directly linked with human mechanisms and processes both in production and in comprehension. For example, speech sounds are inseparably related to the speakers vocal mechanisms, and therefore convey information on the mental and physical states of the speaker to the listener. Studies on spoken language communication thus involve not only linguistics, phonetics, and acoustics, but also psychology, physiology, physics, and in many cases also pathology and pedagogy. It is my belief that we need to study spoken language from all these viewpoints, and share and integrate the findings in our quest for the solution of a problem, regardless of whether it is basic or applied.
