粤方言区日语学习者的塞音持阻时长听辨实验研究

Auditory Discrimination of Closure Duration of Plosives: an Experiment on Japanese Learners in Yue Region

塞音持阻时长的听辨实验利用3组含有清塞音[k]、[p]、[t]的直音和促音,以塞音的持阻时长为变数,用2000型SUG I语音分析系统合成60个实验用语料,请33名日语母语被试和97名日语专业3年级的粤方言区学习者被试进行听辨,以验证他们在直音和促音的辨认率上存在的差异。实验研究表明,两组被试在[p]和[t]的辨认率上存在明显差异。通过分析可知,这些差异源于粤方言区日语学习者对直音和促音辨认的不稳定性,与塞音生成过程中对持阻时长控制不当有一定关系。

60 testing items were obtained by SUGI Speech Analyzer （2000） , based on three groups of palatalized sounds and choked sounds that contain voiceless plosives [ k], [ p] and [ t], and with closure duration as a variable. 33 Japanese native speakers and 97 senior college Japanese learners who have grown up in the Yue-speaking areas were invited as subjects to participate in the experiment of auditory discrimination, so as to discover the differences between them in the rate of discrimination as regards palatalized sounds and choked sounds. We find that the two groups of subjects exhibit significant differences in the rate of discrimination on [ p ] and [ t]. An analysis of the disparities concludes that they are due to the instability of subjects＇ discrimination of palatalized sounds and choked sounds, and their improper control of the closure duration when they are articulating the plosives.
