CSD Labs

Our research facilities are located in the ComArtSci and the Oyer Speech & Hearing buildings on the Michigan State University campus. There are eight research laboratories, as well as shared research spaces for faculty and student use. These communication labs have several sound-treated booths, an anechoic chamber, as well as a highly reverberant room. All laboratories are equipped with state-of-the-art hardware and software to enable researchers in conducting the highest quality research. The department also provides several opportunities, space and resources for students (undergraduate and graduate) to participate in research.

Research Laboratories

Auditory Perception Laboratory

The Auditory Perception Laboratory conducts research on speech understanding difficulties of older, hearing impaired listeners, and to explain contributing factors to individual differences in the hearing ability of older individuals. This research seeks to improve the assessment and rehabilitation of individuals who have a hearing loss.

Brain Systems for Language Lab

The Brain Systems for Language Lab conducts research on the development of neural processes for language and attention, and the interactions between them, with a focus on understanding the effects of early life experiences on the development of these neural systems. This research seeks to improve our understanding of language and attention processes that underlie communication disorders, specifically language impairment and stuttering. It also aims to inform diagnosis and the development of treatment programs for these disorders.

Cognitive Neuroscience of Language Development Lab

The Cognitive Neuroscience of Language Development Lab conducts research on neurocognitive mechanisms that underlie language development and disorders in monolingual and bilingual children. The lab has a focus on reading, studying neural correlates of reading in bilingual and multilingual children and adults. It also studies early identification and intervention of developmental dyslexia using a multimodal neuroimaging method.

MSU Speech Perception-Production Lab

The MSU Speech Perception-Production Lab conducts research on the mechanisms that underlie speech perception and production by children and adults, with a particular focus on speech prosody (pitch, timing, rhythm and loudness). This research investigates how prosody assists with language learning by infants with and without hearing loss, the perceptual evaluation of speech naturalness and word perception.

Rooms Laboratory

The facilities of the Rooms Laboratory include an anechoic chamber and a reverberant room. Both are used in an ongoing series of psychophysical studies of sound localization and binaural hearing. Goals of this research are to better understand the human ability to localize sounds, and to inform the design of devices that may enhance that ability, especially for persons with hearing loss.

Speech Neurophysiology Lab

The Speech Neurophysiology Lab conducts research on the neural bases of speech perception and production and the pathophysiology of developmental stuttering, using multimodal neuroimaging and behavioral experimentation.

Voice Biomechanics and Acoustics Laboratory

The Voice Biomechanics and Acoustics Laboratory studies all aspects of the voice mechanism and production, which includes a spectrum of topics, from the underlying physiology to the biomechanics and resultant acoustics of voice production to acoustic sound propagation.

Voice and Speech Laboratory

The Voice and Speech Laboratory conducts research on the perception of voice quality and speech intelligibility in patients with a variety of speech, hearing and voice disorders, with a goal to understand and model these behaviors. The findings are applied to develop better tools for the assessment and rehabilitation of patients with voice/speech disorders, early detection of neurological disease and fitting or optimization of digital hearing devices.
