L1 and L2 phonetic reduction in quiet and noisy environments

Peggy Mok, Xiaolin Li, Jingxin Luo, Guo Li


Although talking over noise about highly predictable content is a familiar experience to many people, and that there are extensive but separate lines of research on predictability effects and speech in noise, little is known about the relative strength of noise and predictability factors with respect to phonetic reduction. The current study attempts to fill this gap by examining the effects of noise, lexical frequency, repetition and word class, on the duration, mean intensity and mean F0 of vowels in speakers' L1 Mandarin and L2 English. Our results support the idea that multiple sources contribute to phonetic reduction: effects of predictability factors such as lexical frequency and word class may be dependent on language experience while the Lombard reflex is more automatic and language-independent.
