The University of New Mexico Student Organization for Latin American Studies (SOLAS) presents "An Instrumental Account of s-lenition in Two Dialects of Colombian Spanish" with Richard File-Muriel Friday Oct. 7 from noon to 1 p.m. at the Latin American and Iberian Institute.

File-Muriel examines the temporal and gradient acoustic details found in the voices of sociolinguistic interviewees in Barranquilla and Cali, Columbia, and explains the variables involved in Spanish dialect, including speaking rate, word position, stress and lexical frequency.

File-Muriel is an assistant professor of Spanish at UNM and his areas of research include Spanish phonology, lexical frequency in explaining language variation, sociolinguistics and Colombian varieties of the Spanish language.

The event is free and open to the public.
