Abstract
Frequency characteristics of electromyographic traces from the tongue and lips were studied as a function of class of phonemic input. Previous research has established that there are amplitude increases in the lips while processing bilabial linguistic units such as [p] and in the tongue when processing lingual-alveolar units (like [t]). Preliminary results using variability measures suggest similar conclusions for frequency parameters.
