Prosem Lecture: Speech Rhythms and Neural Encoding: Basic Science to Clinical Application

January 24 @ 12:00 pm - 1:00 pm

Presenter: G. Nike Gnanateja, Post-Doctoral Research Associate, Department of Communication Science and Disorders at the University of Pittsburgh
Topic: Speech Rhythms and Neural Encoding: Basic Science to Clinical Application

Speech contains rich rhythmic information across multiple timescales that are vital for accurate speech perception. Among the various rhythms in speech, temporal periodicity and envelope convey majority of the information in speech. Temporal periodicity is a vital cue that conveys information about pitch and intonation which are fundamental for perceiving speech in the presence of noise. The temporal envelope is vital for segmenting speech into syllables and phonemes and is conveys most intelligible information in speech. The processing of these speech rhythms can be studied using non-invasive electrophysiological approaches. The electrophysiological markers of processing of speech rhythms afford advantages over conventionally used electrophysiological tools which primarily convey the processing of sound onsets. However, the neurophysiological bases underlying the electrophysiological markers of these rhythms are not clearly understood. Recent studies probing the neural sources underlying the non-invasive electrophysiological markers of auditory processing speech rhythms will be discussed. Additionally, the top-down influences and ecological validity of these electrophysiological markers with reference to clinical application will be discussed.
