This study is an initial attempt to propose listenability formula for English aural textbooks. The study demonstrates the following : (1) The effect of the two factors, articulation rate and length of the unit of utterance, on listening comprehension is calculated upon the results of listening comprehension test scores. The average articulation rate, the average length of the unit of utterance and their standard deviation scores are also calculated to get the constants of the formula. (2) The strength of the relationship between the speech rate and the length of the unit of speech is significantly different depending on type of speech, reading, interview and film dialogue. The ratio of the unit of speech surrounded by pauses which are not placed on a certain kind of grammatical boundary and that of the unit of speech which contains more than two sentences is different among these type. (3) The length of the utterance surrounded by pauses becomes longer as the speech becomes faster, the length of the tone unit becomes longer as the speech becomes faster, and the change of the length of the tone unit with the speed of speech is smaller than that of the length of the utterance surrounded by pauses. (4) Length of the utterance and temporal variables such as speech rate and silent interval are reconsidered from the viewpoint of the listener. Teaching methodologies (listening comprehension) and an apparatus, i.e.an auditory enhancer, are proposed with respect to auditory memory capacity.

本研究是提出英语听力教材可接受性公式的初步尝试。研究结果表明：（1）清晰度和话语单位长度这两个因素对听力理解的影响是以听力理解测试成绩为基础计算的。通过计算平均清晰度、平均话语单位长度及其标准差，得到公式的常数。(2)语速和单位长度之间的关系的强度是显着不同的演讲类型，阅读，采访和电影对话。这三种类型的停顿所包围的单位和包含两个以上句子的单位所占的比例是不同的。(3)由停顿包围的话语的长度随着语音变快而变长，声调单元的长度随着语音变快而变长，并且声调单元的长度随着语音速度的变化小于由停顿包围的话语的长度。(4)话语的长度和时间变量，如语音速率和沉默的时间间隔重新考虑从听者的角度来看。教学方法（听力理解）和设备，即听觉增强器，提出了关于听觉记忆能力。
