About the Lab

The Speech Communication Laboratory is part of the Department of Speech, Language, and Hearing Sciences at the University of Florida. We are engaged in multidisciplinary research on the production and perception of speech by humans, especially adolescents with congenital auditory and motor deficits.


The Speech Communication Laboratory, led by Dr. Matthew Masapollo, studies the nature and development of human speech production and perception, and the nature of the signal properties that underlie successful speaker to perceiver communication. Our overarching goal is to build an integrated understanding of the physiology, acoustics, and perception of speech in order to develop theoretical models of speech processing and mechanistically driven rehabilitation protocols for those negatively affected by neurodevelopmental disabilities involving speech (e.g., stuttering, cleft palate, and congenital deafness).  Our current research areas focus on the learning of speech in infants and young children, normal speech in adults, and the breakdowns of speech in adolescents with sensorimotor deficits. By combining state-of-the-art functional neuroimaging and electromagnetic articulography with behavioral measures, we are helping to elucidate the governing mechanisms involved in sensorimotor integration for speech.

Research areas

Timing, Sequencing, and Coordination of Speech Movements

How do speakers rapidly sequence and coordinate vocal tract movements to impart linguistic structure to the acoustic speech signal? What are the roles of auditory and somatosensory feedback in speech motor sequencing?


Development of Sensory-Motor Connections for Speech

How do self-generated auditory and somatosensory feedback signals associated with the motor production of speech influence the concurrent perception of speech?

Universal Biases and Experiential Influences on Phonetic Perception

What perceptual and cognitive processes allow listeners (both adult and infant) to map the input acoustic signal onto phonetic categories? What is the nature of the information that those processes operate on, and how are those processes shaped by the complex interplay between biology and experience?
