Speech-evoked auditory event-related potentials (ERPs) provide insight into the neural mechanisms underlying speech processing. For this reason, ERPs are of great value to hearing scientists and audiologists. This article will provide an overview of ERPs frequently used to examine the processing of speech and other sound stimuli. These ERPs include the P1-N1-P2 complex, acoustic change complex, mismatch negativity, and P3 responses. In addition, we focus on the application of these speech-evoked potentials for the assessment of (1) the effects of hearing loss on the neural encoding of speech allowing for behavioral detection and discrimination; (2) improvements in the neural processing of speech with amplification (hearing aids, cochlear implants); and (3) the impact of auditory training on the neural processing of speech. Studies in these three areas are reviewed and implications for audiologists are discussed.
言语诱发听觉事件相关电位（ERPs）有助于深入了解言语处理背后的神经机制。因此，ERPs对听力科学家和听力学家具有重要价值。本文将概述常用于检查言语和其他声音刺激处理的ERPs。这些ERPs包括P1-N1-P2复合波、声学变化复合波、失配负波和P3反应。此外，我们重点关注这些言语诱发电位在以下评估中的应用：（1）听力损失对言语神经编码的影响，以便进行行为检测和辨别；（2）放大（助听器、人工耳蜗）对言语神经处理的改善；（3）听觉训练对言语神经处理的影响。本文回顾了这三个领域的研究，并讨论了对听力学家的启示。
