Abstract: Objective To study the comparability between Fencheng dialect and Mandarin in forensic speaker identification, and to explore the acoustic characteristics of Fencheng glottization. Method Acoustic characteristics of Fencheng glottization and corresponding Mandarin syllables, including rhythm and vocal quality, were analyzed qualitatively or quantitatively by a VS-99 workstation. Results The phonation type of Fengcheng glottization is mainly creaky voice. The initial is not affected by the glottization. Moreover, between glottization final and Mandarin final, the consistency in formant frequency outclasses that in relative formant amplitude. Conclusion The present study will provide a basis for fieldwork and speaker identification between Fengcheng dialect and Mandarin.

Key words:  forensic speaker identification, Fencheng dialect, glottization, acoustic characteristic, creaky voice

摘要： 目的 明确山西汾城方言紧喉音节与对应普通话音节在司法话者识别时的可比性及该紧喉音的声学特性。方法 利用VS－99语音工作站对山西汾城方言紧喉音节及对应普通话音节的韵律特性、音质特性等声学特性进行定性与定量分析。结果 得出了汾城方言紧喉音的发声态主要为嘎裂声，汾城方言紧喉音对声母没有明显影响，紧喉音韵母与普通话韵母在共振峰频率上的一致性要远高于共振峰相对强度上的一致性等认识。结论 为在汾城方言与普通话之间进行司法话者识别以及田野调查提供了依据。
