汉语音联可分为:闭音联、音节音联、节奏音联和停顿音联等四级,其中团音朕最强、音节音联次之,另外两种音联较弱。在以音节为基本单元的汉语合成系统中,闭音联已保留在语音库中,因此需要着重考虑的是音节音联。本文以服务于汉语文语转换系统为目的,通过两个阶段的感知实验,研究了汉语音节音联在听觉感知中的作用。得到以下结论:①从总体上看,听音人对汉语双音节词中音高模式的变化的感知比较灵敏,而对音节间共振峰过波段的感知不灵敏,共振峰过波段对合成语音的自然度的影响不显著。②有语音学知识背景的专家或专业人员在判别合成语音的自然度时,比普通听音人更注意音节间的共振峰过渡。但即使是专家,也不容易判别在合成语音中音节间是否包含了共振蜂的平滑过渡。③双音节调的语音结构对音节间共振峰过渡的感知有影响。双音节词的声调组合对它也有一定影响。
Chinese phonetic couplet can be divided into four groups: Achronic couple, Syllable phonetic couple, Rhythm couple and Halt phonetic transcription. Among them, Tongyin 朕 is the strongest, syllable vernal couple is second, and the other two are weaker. In syllables as the basic unit of the Chinese synthesis system, the accent couple has been retained in the speech library, it is important to consider the syllable syllables. The purpose of this thesis is to serve the system of Chinese language conversion, and the effect of Chinese syllable syllables on auditory perception is studied through two stages of perceptual experiments. The following conclusions are drawn: (1) Generally speaking, the listener perceives the change of pitch pattern in Chinese disyllabic words more sensitively, but not sensitive to the over-syllable resonance between syllables, The effect of natural degree is not significant. ② Phonetics knowledge background experts or professionals in the determination of the natural degree of synthetic speech, pay more attention to the transition between the resonance of syllables than ordinary listeners. But even experts, it is not easy to distinguish whether the syllables in the synthesized speech contain a smooth transition of resonant bees. ③ The disyllabic speech structure has an impact on the perceived resonance between syllables. The tone combination of disyllabic words also has some effect on it.
