Do tre la noi cac cong cu tren trinh duyet lien tuc roi ngan, va no quan trong hon hang tram nguoi mong doi.
Khi ban nghe giong noi cua chinh minh voi do tre 200+ ms, dieu do tao ra mot hien tuong goi la delayed auditory feedback (DAF). Nao cua ban mong doi nghe thay giong noi cua ban nguyen ban tuc thoi.
