在《名词解释》的这一部分，你可能会惊奇地发现有很多词语其实并没有在本书中出现过。我把这些专业名词添加进来，是考虑到一些读者在语言病理学方面的知识可能还比较匮乏。这些额外添加的专业名词，常常会出现在口吃问题的相关书籍当中；而对于这些专业名词的准确意思，很多读者可能并不大了解。通过阅读本文，这部分读者可以学习到更多的有关于口吃的知识。
为了方便各位读者进一步的查阅相关外文资料，并且最大限度的减少出错率。在名词解释这一部分，我采取了同时列出“原文解释”和“相应中文翻译”的方式，方便大家进行对照查阅。如果你在阅读的过程中，发现我的翻译有任何错误的地方，也欢迎你给我指正出来，谢谢了！
这份《名词解释》是按照相应英文术语的字母顺序排列和组织的。
在名词的具体解释当中，黑体加粗的词语表示该名词本身也是一个专业名词，在本文中你可以找到它的具体解释。
T字头～W字头部分（X、Y、Z字头术语暂无）
- Tension. Mental, emotional, nervous or physical strain, often resulting in unnecessary intensity that disturbs normal functioning of the organs of speech.
紧张（Tension）：这指的是精神上的，情感上的，神经性的或生理性的绷紧状态。“紧张”常常会导致不必要的僵硬状态，这种僵硬状态会扰乱语言器官的正常机能。 - Therapy. The prevention, early intervention and treatment of any clinically significant condition such as stuttering.
治疗（Therapy）：这指的是对于任意一种典型的临床状态（比如：口吃）所进行的预防、早期干涉和治疗行为。 - Tic. A sudden spasmodic and purposeless movement of some muscle or muscle group, particularly of the face, usually occurring under emotional stress. Possibly organic or psychogenic in origin.
痉挛（Tic）：这指的是身体某部分的（特别是脸部）某条肌肉或肌肉群所出现的一种突然的间歇性的无目的的运动。“痉挛”通常是在情感压力下产生的。其起因既可能是生理性的，也可能是心理性的。 - Time pressure. At the moment the stutterer is expected to speak he often has an almost panicky feeling of haste and urgency. He feels he is under “time pressure” and with no time to lose, and so he has a somewhat compulsive feeling that he must speak instantly without allowing time for deliberate and relaxed expression.
时间压力（time pressure）：当口吃者想要说话时，他常常会有一种匆忙的，着急的，甚至是惊慌失措的感觉。他会感觉自己处于“时间压力”之下，觉得自己的时间所剩无几，进而会产生一种几乎强制性的错觉，觉得自己必须立刻把话说完，觉得自己没有时间来进一步地思考，没有时间来放松地进行语言表达。 - Transfer. The process of generalizing a newly acquired behavior to new and different environments: for example, the transfer of improved fluency from the therapy room to the classroom or to the home or office. Sometimes referred to as “carry-over.”
迁移（transfer）：这指的是把一种新学到的行为推广到一个新的不同环境当中——比如说，把从治疗室中所获得的改善的语言流畅表达方式迁移到学校教室中，或迁移到家中或办公室中。有时这也被称作“拓展（carry-over）”。 - Tremor. A localized quivering or vibratory motion of a muscle or muscle group when an articulatory position is suddenly invested with localized hypertension.
颤动（Tremor）：这指的是当某个发音部位突然变得局部高度紧张时，某条肌肉或肌肉群所做出的一种局部的颤抖或振动运动。 - Vocal cords. Synonymous with vocal folds. The opening and closing of the vocal folds is responsible for the production of laryngeal voicing.
声带（vocal cords）：为“声襞”的同义词。声带的开放和闭合是喉部语音产生的原因。 - Voice. Sound produced by vibration of the vocal folds and modified by the resonators.
语音（voice）：指的是由声带振动产生的，经口腔共鸣所修正的声音。 - Voice onset time (VOT). The length of time, measured in milliseconds, between the onset of an external signal such as a tone or light and the initiation of phonation.
语音启动时间（VOT）【voice onset time (VOT)】：其以毫秒为单位进行计算，指的是从一个外部信号（诸如一个声音或光线）的出现到发声的开始的这个过程的时间长短。 - Voluntary stuttering. This may refer to attempts made by the stutterer to imitate or duplicate as closely as possible, or with specific predetermined modifications, his usual, habitual, pattern of stuttering. It may also take the form of easy prolongations or relatively spontaneous and effortless repetitions of sounds, syllables or the word itself. This style of talking may be used as a deliberate replacement for the usual stuttering behavior and is intended to reduce fear of difficulty by voluntarily doing that which is dreaded. This conscious, purposeful stuttering is also designed to eliminate other avoidance reactions. For the purpose of desensitization some clinicians ask the stutterer to add tension and struggle to these voluntary stutterings in order to learn how to better cope with them. (See pseudo-stuttering.)
故意口吃（Voluntary stuttering）：这指的是：口吃者以一种尽量接近真实的方式，或是以一种预先修订好的方式，来模仿或复制自身平常的、习惯性的口吃方式。“故意口吃”要求口吃者在说话时要尽量放松地拖长语音、音节或整个词语，或是要相对自然地松弛地进行语言的重复。
口吃者可以有意识地用“故意口吃”来替代自己习惯性的口吃方式。并且，通过使用这种说话方式，口吃者主动地去实践那些自己所畏惧的事情，进而减轻了自身对于口吃的恐惧感。这种故意的，有目的性的口吃行为同时也被用来消除其他的逃避性反应。
为了帮助口吃者进行脱敏，一些临床矫正师要求口吃者在“故意口吃”的同时，加上紧张感和挣扎行为，以便于从中学会怎样更好地去应付这些问题。（参见 假冒性口吃） - Vowel. A voiced speech sound in which the oral part of the breath channel is not blocked and is not constricted enough to cause audible friction: broadly, the most prominent sound in a syllable.
元音（vowel）：这指的是语言表达语音中的一种，由通过咽喉和口腔中相对自由的气息而发出：广义上讲，指的是在一个音节中最显著的那个音。 - Whisper. Speech without vibration of the vocal cords.
耳语（whisper）：这指的是压低嗓音说出的轻声话语。
