基于语料语义的脑电反应一致性研究
A study of EEG response coherence based on corpus semantics
摘要
Abstract
This study examined the response tendency of the human brain to a standardized corpus of speech by measuring changes in speech-related electroencephalographic(EEG)signals.Sixteen participants listened to 120 standardized speech items,each lasting 8 seconds,with intervals of 1 to 2 seconds between them and played in a random order.During the listening process,the EEG signals were extracted from the participants,and the signals within the frequency band of 1-40 Hz were preprocessed and analyzed in comparison with the speech signals.The results showed that participants exhibited similar EEG response trends when exposed to the same standardized speech.Furthermore,phase difference analysis between EEG and speech signals was conducted using the phase loc-king value method,which demonstrated the functional connectivity between EEG signals and speech quality.Notably,the EEG signals achieved a 99.62%accuracy in distinguishing speech quality.关键词
