The department research facilities are located in the CAS and the Oyer Speech & Hearing buildings within the MSU campus. There are five research laboratories, as well as a shared research spaces for faculty and student use. These laboratories 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:

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

Auditory Perception Laboratory
This lab conducts research on the speech understanding difficulties of older hearing-impaired listeners and to explain factors that contribute to individual differences in the hearing abilities of older individuals. This research seeks to improve the assessment and rehabilitation of individuals who have a hearing loss.

MSU Speech Perception-Production Lab
This 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.

Voice and Speech Laboratory
This lab 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 then 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.

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.
