在口语产生理论中，规定言语器官运动的手势代码通常被视为整体的、封装的、硬连线的语音计划的线性串，例如，指音素或音节的大小。显性言语表面语音单位之间的相互作用通常归因于语音编码阶段或言语器官的外围机制。言语失用症是一种神经源性疾病，被认为是干扰语音编码机制。摘要对失读性言语错误的分析表明，语音表征具有非线性、层次嵌套的结构。本文提出了一个非线性概率模型的语音代码，它包括从一个子音段水平的单位，以格律英尺的水平。该模型是验证的基础上，从一个大样本的apraitanspeakers的准确性数据。
In theories of spoken language production, the gestural code prescribing the movements of the speech organs is usually viewed as a linear string of holistic, encapsulated, hard-wired, phonetic plans, e.g., of the size of phonemes or syllables. Interactions between phonetic units on the surface of overt speech are commonly attributed to either the phonological encoding stage or the peripheral mechanisms of the speech apparatus. Apraxia of speech is a neurogenic disorder which is considered to interfere with the mechanisms of phonetic encoding. Analyses of apraxic speech errors have suggested that phonetic representations have a non-linear, hierarchically nested structure. This article presents a non-linear probabilistic model of the phonetic code, which embraces units from a sub-segmental level up to the level of metrical feet. The model is verified on the basis of accuracy data from a large sample of apraxic speakers.
