【摘 要】 不同人所讲的普通话语流中相邻音素间的过渡方式分为不同的类型。音节内辅音-元音之间、音节间元音-辅音之间的过渡方式分为清晰过渡（或停顿过渡）和模糊过渡（或缓冲过渡）两种类型；音节内元音-辅音之间的过渡方式分为间断过渡和连续过渡两种类型； 音节内元音-元音之间的过渡方式分为平滑过渡、间断过渡、交错过渡和异变过渡四种类型。对同一人的发音而言，不论其相邻音素间的过渡方式属于上述哪种类型，都表现出较强的自身同一性。 因此音素间的过渡方式可以作为声纹鉴定中的一类特征。

A Research on Transition Patterns between Adjacent Phonemes of Mandarin in Voice Identification. Wang Yingli. Forensic Science Center of Guangdong Bureau of Public Security , Guangzhou, 510050

【Abstract】 Different speakers present different transition patterns between adjacent phonemes in the connected speech of Mandarin. Consonant-vowel transition within syllable and vowel-consonant transition among syllables can be classified as clear transition (or pausing transition) and fuzzy transition (or buffering transition). Vowel-consonant transition within syllable can be assigned to gap transition and continuous transition. Vowel-vowel transition within syllable can be labeled as smooth transition, gap transition, interlaced transition and variant transition. As the transition pattern shows a large inter-speaker variation and a little intra-speaker variation, it becomes a very discriminatory feature for forensic voice identification.
