Specific computer-based auditory training may be a useful completion in the rehabilitation process for cochlear implant (CI) listeners to achieve sufficient speech intelligibility. This study evaluated the effectiveness of a computerized, phoneme-discrimination training programme.
The study employed a pretest-post-test design; participants were randomly assigned to the training or control group. Over a period of three weeks, the training group was instructed to train in phoneme discrimination via computer, twice a week. Sentence recognition in different noise conditions (moderate to difficult) was tested pre- and post-training, and six months after the training was completed. The control group was tested and retested within one month.
Twenty-seven adult CI listeners who had been using cochlear implants for more than two years participated in the programme; 15 adults in the training group, 12 adults in the control group.
Besides significant improvements for the trained phoneme-identification task, a generalized training effect was noted via significantly improved sentence recognition in moderate noise. No significant changes were noted in the difficult noise conditions. Improved performance was maintained over an extended period.
Phoneme-discrimination training improves experienced CI listeners' speech perception in noise. Additional research is needed to optimize auditory training for individual benefit.
特定的基于计算机的听觉训练可能是人工耳蜗（CI）使用者康复过程中的一项有益补充，有助于实现足够的言语清晰度。本研究评估了一个计算机化的音素辨别训练项目的有效性。
本研究采用前测-后测设计；参与者被随机分配到训练组或对照组。在三周的时间里，训练组被指导通过计算机进行音素辨别训练，每周两次。在训练前、训练后以及训练完成六个月后，测试不同噪声条件（中度至困难）下的句子识别能力。对照组在一个月内进行测试和重新测试。
27名使用人工耳蜗超过两年的成年CI使用者参与了该项目；训练组15名成年人，对照组12名成年人。
除了经过训练的音素识别任务有显著改善外，还通过在中度噪声中句子识别能力的显著提高，观察到了一种普遍的训练效果。在困难噪声条件下未观察到显著变化。改善后的表现持续了较长时间。
音素辨别训练可提高有经验的CI使用者在噪声中的言语感知能力。需要进一步研究以优化听觉训练，使其对个体更有益。
