口语语篇的理解虽然表面上看起来很容易，但实际上却是一个复杂的语言和认知过程。当语音退化时，这种操作的难度会增加，就像人工耳蜗使用者的情况一样。然而，降级语音所带来的额外挑战可能会在一定程度上被语言背景和呈现节奏所缓解。一个实验中，年轻的成年人与年龄正常的听力回忆话语段落听到清晰的语音或噪声带声码用于模拟人工耳蜗植入产生的语音的声音。段落在词间可预测性方面各不相同，并且要么不中断地呈现，要么以允许听者控制信息传递速率的自定步调格式呈现。结果表明，清晰的语音听到的话语比语音编码的话语更好地回忆，话语具有较高的平均词间可预测性比话语具有较低的平均词间可预测性更好地回忆，和自定节奏的段落回忆好于那些听到没有中断。特别令人感兴趣的是语义层次效应：听众倾向于对主要思想的回忆比对文章中的中级信息或细节的回忆更好，这是听众理解文章含义的能力的指标。这些数据揭示了词间可预测性的显着影响，在具有较低的可预测性的通道有一个衰减的语义层次结构的影响相对于较高的可预测性通道。结果进行了讨论，扩大人工耳蜗植入的结果措施超出目前的临床措施，重点是单个单词和句子的重复。
In spite of its apparent ease, comprehension of spoken discourse represents a complex linguistic and cognitive operation. The difficulty of such an operation can increase when the speech is degraded, as is the case with cochlear implant users. However, the additional challenges imposed by degraded speech may be mitigated to some extent by the linguistic context and pace of presentation. An experiment is reported in which young adults with age-normal hearing recalled discourse passages heard with clear speech or with noise-band vocoding used to simulate the sound of speech produced by a cochlear implant. Passages were varied in inter-word predictability and presented either without interruption or in a self-pacing format that allowed the listener to control the rate at which the information was delivered. Results showed that discourse heard with clear speech was better recalled than discourse heard with vocoded speech, discourse with a higher average inter-word predictability was better recalled than discourse with a lower average inter-word predictability, and self-paced passages were recalled better than those heard without interruption. Of special interest was the semantic hierarchy effect: the tendency for listeners to show better recall for main ideas than mid-level information or detail from a passage as an index of listeners’ ability to understand the meaning of a passage. The data revealed a significant effect of inter-word predictability, in that passages with lower predictability had an attenuated semantic hierarchy effect relative to higher-predictability passages. Results are discussed in terms of broadening cochlear implant outcome measures beyond current clinical measures that focus on single-word and sentence repetition.
