Speech Acoustics Lab
Focus of Lab
The overarching goal of the Speech Acoustics Lab is to contribute to the understanding of speech motor control through examining the acoustic correlates of speech. Current projects of the laboratory focus on variability in the speech acoustic signal and its potential implications for speech motor processing. Specifically, within-speaker variability, one form of variability in speech, is studied as a manifestation of changes made by the speech motor control system to meet different communicative demands (e.g., formal vs. casual styles of speaking). In current research projects, different speaking tasks (e.g., reading vs. conversation) are designed and implemented to represent a range of communicative demands.
The speech acoustic output has been well-documented for its significant implications for both articulatory behaviors and speech perception. In addition to acoustic analysis of speech, the laboratory also incorporates the use of perceptual measures in further establishing the acoustic-perceptual link.
