在针对轻声音节的研究中，有关普通话轻声音节的文献较多，但有关方言区母语者为主体的研究甚少。另外，粤方言中并无轻声现象的存在，因此，本文选择以粤方言母语者为主体，展开其对普通话轻声音节感知的调查。此研究可以让我们了解粤方言母语者轻声习得的现状，了解其轻声音节掌握的特点。
本文的研究主要以问卷调查的方法，考察粤方言母语者对各类型普通话轻声的感知情况。问卷由三部分组成，第一部分为基本信息调查；第二部分关于普通话水平测试；第三部分为各类轻声词，包括有规律轻声以及无规律轻声。
本文的主要结论为：1、普通话水平测试有利于加强轻声音节的了解，曾经参与普通话水平测试的调查对象在轻声词的理解上更为准确；2、相比于语法层面的轻声音节，词汇层面的轻声音节更易掌握；3、在语法层面上，粤方言与普通话差异较大的轻声音节较难掌握；4、无规律轻声词较难掌握。

There are many literatures about neutral tone syllables in Putonghua, but there is few research about native speakers in dialect areas. In addition, there is no neutral tone phenomenon in Cantonese dialect. Therefore, this paper chooses Cantonese native speakers as the main body to carry out an investigation on their perception of neutral tone syllables in Mandarin.
This study can help us understand the current situation of the acquisition of neutral tones by Cantonese native speakers and the characteristics of their neutral tones.
The research of this paper is to investigate the perception of different types of Putonghua neutral tone syllables by Cantonese native speakers. The survey was conducted mainly through questionnaires. The questionnaire consists of three parts. 
The first part is basic information survey. The second part is about Putonghua proficiency test. The third part is different kinds of neutral tone, including regular neutral tone and irregular neutral tone.
The main conclusions of this paper are as follows. Firstly, Putonghua test is helpful to strengthen the understanding of neutral tone syllables. Secondly, compared with the neutral tone syllables in grammar, the syllables in vocabulary are easier to master.Thirdly, in terms of grammar, it is difficult to master the neutral tone syllables that are quite different from Mandarin. Forth, irregular neutral tone words are difficult to master.
