The ACSL addresses
issues relating to the processing of complex acoustic signals such as
speech, music, and other environmental sounds. Current projects include examining
how people learn the sounds of a 2nd language and how one’s native
language can interfere with this learning; investigating the ability of
listeners to “tune” their perception to the particular
characteristics of a speaker (e.g., understanding someone with a foreign
accent or disordered speech); and studying how the design of cochlear
implants and hearing aids can affect the ability of listeners to understand
speech in complex listening environments. This multidisciplinary lab works
closely with researchers in Psychology, Linguistics, Neurophysiology, and
Electrical Engineering.

phonetic categorization to spoken language perception: Sometimes a [ga] is
only a [ga]” talk.
