    摘要:

    通过测量语音相关的脑电信号变化来研究人脑对于标准语料的反应趋势.有16名被测者分别聆听了120条标准语音,每条8 s,语音之间有1~2 s的间隔且随机播放.提取被测者在聆听过程中的脑电信号,对1~40 Hz频段的脑电信号进行预处理并将其与语音信号进行分析比对.结果显示,被测者听到相同标准语音时有相同的脑电反应趋势.通过相锁值方法对脑电信号和语音信号进行相位差分析,证明了脑电信号与语音质量之间的功能连接性,并且脑电信号区分语音质量的正确率达到99.62%.

    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 locking 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.
