The process of learning new electrically stimulated speech patterns can be difficult for many cochlear implant users, especially congenitally deafened patients. Some implant users receive little benefit from the device, even after long-term experience. While many factors may influence individual patient outcomes, the paucity of auditory rehabilitation resources, especially for adult users, may contribute to some implant patients' poorer performance. The present study examined whether moderate auditory training, using speech stimuli, can improve the speech-recognition performance of adult cochlear implant patients. Ten cochlear implant patients with limited speech-recognition capabilities used a recently developed computer-based auditory rehabilitation tool to train at home for a period of one month or longer. Before training began, baseline speech-recognition performance was measured for each patient; baseline performance was measured for at least two weeks, until performance asymptoted. After baseline measures were complete, subjects were instructed to train themselves at home using novel monosyllable words one hour per day, five days per week. Subjects then returned to the lab every two weeks for retesting with the baseline speech materials. Preliminary results showed that there was significant improvement in all patients' speech perception performance after moderate training. While most patients did improve, the amount and time course of improvement was highly variable. Moderate training using a computer-based auditory rehabilitation tool can be an effective approach to improve cochlear implant patients' speech recognition, especially for poorer-performing implant users.
对于许多人工耳蜗使用者来说，学习新的电刺激语音模式的过程可能会很困难，尤其是对于先天性耳聋患者。一些植入者即使经过长期使用，从该设备中获得的益处也很少。虽然许多因素可能会影响个体患者的治疗效果，但听觉康复资源的匮乏，尤其是针对成年使用者的资源匮乏，可能是导致一些植入患者表现较差的原因之一。本研究探讨了使用语音刺激进行适度的听觉训练是否能提高成年人工耳蜗患者的语音识别能力。十名语音识别能力有限的人工耳蜗患者使用一种新开发的基于计算机的听觉康复工具在家中训练了一个月或更长时间。在训练开始前，测量了每位患者的基线语音识别能力；基线能力至少测量了两周，直到能力趋于稳定。在完成基线测量后，受试者被要求在家中每天使用新的单音节词进行一小时的自我训练，每周训练五天。然后，受试者每两周返回实验室，使用基线语音材料进行重新测试。初步结果表明，经过适度训练后，所有患者的语音感知能力都有显著提高。虽然大多数患者确实有所改善，但改善的程度和时间进程差异很大。使用基于计算机的听觉康复工具进行适度训练可能是提高人工耳蜗患者语音识别能力的有效方法，尤其是对于表现较差的植入使用者。
