原住民的声音与易懂的声音。长期以来，这在语言学习中一直是一个有争议的问题，许多教师声称，发音应是目标。可理解性的物理定义是什么？目前的工作为这个问题提供了一个非常好的候选答案。作者提出了一种基于结构音系学的言语声学观察范式，将所有类型的言语事件视为一个完整的结构，并证明这个结构与任何静态的非语言特征如年龄、性别、大小、形状、麦克风、房间、线条等都是数学上不变的。这种声学结构是纯语言的，音素层次结构被认为是个别学生的发音结构。将这种结构与另一种语言结构，即目标语的词汇结构进行匹配，并计算出两种不同层次结构之间的相容程度，这在本文中被定义为可理解性。为了增加可理解性，应该为不同的学生准备不同的指导，因为没有两个学生是相同的。该方法可以显示音素的学习顺序，既适合于学生，又不同于其他方法。
Native-sounding vs. intelligible. This has been a controversial issue for a long time in language learning and many teachers claim that the intelligible pronunciation should be the goal. What is the physical definition of the intelligibility? The current work shows a very good candidate answer to this question. The author proposed a new paradigm of observing speech acoustics based upon structural phonology, where all the kinds of speech events are viewed as an entire structure and this structure was shown to be mathematically invariant with any static non-linguistic features such as age, gender, size, shape, microphone, room, line, and so on. This acoustic structure is purely linguistic and the phoneme-level structure is regarded as the pronunciation structure of individual students. This structure is matched with another linguistic structure, the lexical structure of the target language, and degree of compatibility between the two different levels of structures is calculated, which is defined as the intelligibility in this work. To increase the intelligibility, different instructions should be prepared for different students because no two students are the same. The proposed method can show the order of phonemes to learn, which is appropriate to a student and different from that of the others.
