声学实验和听感实验证明,确定句义下“都”歧义结构中“都”所强调部分的声学要素的变化具有比较一致的倾向性和规律,这些倾向性在有声语言使用的大多数情况下能让信息接收者正确地感知。此类“都”字歧义是一种可以通过语音手段得到消解的歧义。在语音形式上,都2不太稳定,比“都1”弱,比“都3”强,体现出处于语法化过渡阶段的两面性。 Acoustic experiments and auditory experiments prove that it is more consistent and regular to determine the change of acoustic elements in the emphasized parts of “ In most cases it allows the recipient of the message to perceive it correctly. The ambiguity of such ”“ is a type of ambiguity that can be resolved by phonetic means. In the phonetic form, both are less stable, weaker than ”1“, ”stronger than 3", reflecting the dual nature of being in the transitional stage of grammaticalization.
