Characterizing speech rhythm using spectral coherence analysis of jaw kinematics and speech temporal envelope: A proof of concept
Keyword(s):
Lower modulation rates in the temporal envelope (ENV) constitute the rhythmic frames in speech and are crucial for speech comprehension in terms of neuronal entrainments at δ- and θ-rates. The jaw plays the role of a carrier articulator producing the low-frequency modulations in this process. This paper introduces a method to examine the joint roles of jaw oscillation and ENV in formulating rhythmic frames using spectral coherence. Relative powers in the frequency bands corresponding to the δ- and θ-oscillations were quantified and regressed on utterance duration. Two English corpora were analyzed for the proof of concept.
