Abstract

The present study investigates the articulatory and acoustic properties of the unique apical segments in Mandarin Chinese that occur after dental and retroflex sibilants instead of the high front vowel [i]. An ultrasound study showed that the segments are homorganic with the preceding dental and retroflex sibilants. However, an acoustic study showed that they have a periodic waveform and clear formant structures with no inherent frication noise, indicating that they are not 'voiced fricatives'. The results also suggest that the observed F2 pattern can only be explained with an acoustic model of a sonorant consonant, wherein F2 is attributed to the cavity behind the apical constriction. Based on this, it is argued that the segments can be best seen as 'dental approximant [ė]' and 'retroflex approximant [ė]'. A phonological implication of the pattern is also discussed: the co-occurrence restriction with the high front vowel eliminates a potential chance of palatalization of the dental and retroflex sibilants that may lead to neutralization of the place contrast. The tongue front gesture in the following approximants seems to provide an additional cue to the place of the preceding consonants; the low F3 of [ė], for example, enhances cues to the place of the preceding retroflex sibilant.
