内容简介：

Second language (L2) speech learning entails the learning of both segmental (i.e., vowels and consonants) and suprasegmental aspects (i.e., tones, intonation, rhythm, stress, prosodic phrasing, and so on). Due to the phonetic and phonological difference in segmental and suprasegmental aspects between L2 and the learners’ native language (referred to as L1), L2 learners may have difficulty in acquiring some aspects of L2 speech. Different aspects of L2 speech, however, may affect L2 speech perception and comprehension to varying degrees. While previous studies have examined the effects of segments, intonation, rhythm and fluency on L2 perception and comprehension, many studies have adopted different research paradigms, which renders their findings somewhat incomparable. More importantly, previous studies have only focused on European languages and non-European languages, such as Chinese, have not been investigated. To this end, this paper examines the roles of segments, intonation and rhythm on the perception of L2 accentedness and comprehensibility by focusing on a tone language, Mandarin Chinese. 15 Chinese sentences were manipulated by transferring the segments, intonation and rhythm between L1 and L2 speakers. 64 Chinese native judges listened to the original and manipulated sentences and were asked to rate their accentedness and comprehensibility. Results of the Chinese judges’ accentedness and comprehensibility ratings showed that segments contribute more to the perception of L2 accentedness and comprehensibility than intonation and rhythm, and that intonation contributed more to L2 perception than rhythm. It was also found that accentedness rating highly correlated with comprehensibility judgment. The findings of this study confirm what some recent studies have found regarding the contribution of segments and prosody to L2 perception, but differ from some previous studies in regards to the relationship between accentedness and comprehensibility. The theoretical and pedagogical implications of this study will also be discussed.
