| Abstract | This study aimed to investigate the effect of the unfamiliar stressed prosody on spoken Thai word perception in thepre-attentive processing of the brain evaluated by the N2a and brain wave oscillatory activity. EEG recording was obtainedfrom eleven participants, who were instructed to ignore the sound stimuli while watching silent movies. Results showed thatprosody of unfamiliar stress word perception elicited N2a component and the quantitative EEG analysis found that theta anddelta 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 wordsinduced highly selective attention and retrieval of information from the episodic memory of the pre-attentive stage of speechperception. This brain electrical activity evidence could be used for further study in the development of valuable clinical teststo evaluate the frontal lobe function in speech perception. |
