| 摘 要： | 听觉训练可以提升人在噪声环境中语音识别的绩效.首先设计了一种以稳定声源为刺激的听觉追踪任务,在20个训练单元后,采用由干扰语音类型和信噪比两个因素构成3×5语音型噪声掩蔽下的语音识别测试验证了该训练方法的有效性.结果发现,训练组的语音识别率显著高于对照组,证明听觉注意力可以通过声源追踪任务的训练得到提高。实验结果表明,声源追踪训练可以使人在语音型噪声掩蔽下的听觉注意力水平趋于稳定。

| Abstract: | Auditory training may strengthen auditory skills that help human not only in on-task auditory perception performance but in continuous speech-shaped noise environment.Firstly,a short-term and simplified training method was designed which adopted stable stimuli tracking to train the participants.After twenty training units,the validity of training method was verified by speech-in-noise perception under the 3×5 noise composed of two factors:types of interference speech and the signal-to-noise ratio.As a result,the training group presented significant better speech perception performance than control group.Outcome suggest that efficacy of auditory target tracking training can improve speech perception performance and selective attention during speech-shaped noise environment.These findings provide an effective method to promote auditory selective attention in real-world,and extended to special vocational training. |
