動態神經振盪支撐視覺唇形提示在語音噪音中的視聽增益

// Dynamic neural oscillations underpin audiovisual gain from visual lip cues in speech noise

研究探討視覺唇動如何在噪音下幫助普通話句子語音辨識｜噪音降低辨識率並削弱聽覺腦區神經活動與連結｜唇動同步提升辨識率及早期低頻神經反應，且在高噪音時強化與運動區的連結，暗示感覺運動區補償作用。

// This study investigated how visual lip movements aid speech perception in noisy Mandarin sentences using behavioral and EEG data. It found that speech noise reduces recognition accuracy and weakens neural activity and connectivity in auditory brain regions. Congruent lip movements improved recognition and enhanced low-frequency brain activity in these regions early after speech onset. Under very noisy conditions, visual lip cues also increased connectivity with motor areas, suggesting compensatory sensorimotor involvement in difficult listening.
