| Summary: | This study aimed to investigate the effect of the unfamiliar stressed prosody on spoken Thai word perception in the
pre-attentive processing of the brain evaluated by the N2a and brain wave oscillatory activity. EEG recording was obtained
from eleven participants, who were instructed to ignore the sound stimuli while watching silent movies. Results showed that
prosody of unfamiliar stress word perception elicited N2a component and the quantitative EEG analysis found that theta and
delta wave powers were principally generated in the frontal area.
It was possible that the unfamiliar prosody with different frequencies, duration and intensity of the sound of Thai words
induced highly selective attention and retrieval of information from the episodic memory of the pre-attentive stage of speech
perception. This brain electrical activity evidence could be used for further study in the development of valuable clinical tests
to evaluate the frontal lobe function in speech perception.
