Description of Research

Summary Statement of Research Interests

Professor Byrd's special interest is in speech production and articulation. She studies how the skilled, sound producing movements of the vocal tract are coordinated in time as a result of linguistic structuring, such as phrase and syllable structure. In order to study speech production, she uses cutting edge technology for tracking and imaging inside the mouth and throat during speech, including magnetometry and real-time MRI. Her research is supported by the NIH.

Spoken language relies on an elegant and complex acoustic structure to support communication between speakers and listeners. Consideration of the orchestration of articulatory activity that produces this acoustic signal is a necessary element in understanding the process of human communication. The complex messages and emotions of spoken language must be communicated by precise choreography of the jaw, tongue, lips, larynx, and respiratory system. This choreography is shaped by the structure of the language being spoken but is constrained by the shared biology of the human organism producing the linguistic message.

Phonetics is an interdisciplinary area of research, which in addition to requiring an understanding of linguistics, incorporates elements of cognitive science, motor control, acoustics, engineering, physiology, and psychology. Professor Byrd considers her work in speech production to be part of the growing interdisciplinary research effort in cognitive science, adopting the view that the study of language is one of the cornerstones of this effort as it is a special human ability that makes possible the richness of human intellect, relationships, culture, and technology.
