This clinical trial investigated the ability of concurrent speech segregation in hearing impaired children. The auditory behavioral responses and auditory late responses (ALRs) were compared between test and control groups prior to vowel auditory training and after 3 and 6 months of vowel auditory training to find the effects of bottom-up training on concurrent speech segregation in hearing impaired children.
Auditory behavioral responses for 5 vowels and ALRs for double synthetic vowels, with special physical properties, were recorded in a timetable in 30 hearing impaired children (test group = 15 and control group = 15).
Identification score and reaction time data showed that the test group was approximately proficient for some vowels (P < .05 for vowels /æ/, /e/, and /u:/) and took less time to process after 6 months of training. N1-P2 amplitude indexing of the vowel change detection and reflecting central auditory speech representation without active client participation has been increased in the test group (P < .05).
The present study showed training-related improvements in concurrent speech segregation. This information provided evidence for bottom-up training based on F0, its differences in auditory scene analysis, and neural underpinnings.
本临床试验研究了听力受损儿童同时进行语音分离的能力。在元音听觉训练前以及训练3个月和6个月后，比较测试组和对照组的听觉行为反应及听觉晚期反应（ALRs），以探究自下而上训练对听力受损儿童同时进行语音分离的影响。
在时间表中记录了30名听力受损儿童（测试组 = 15名，对照组 = 15名）对5个元音的听觉行为反应以及对具有特殊物理特性的双合成元音的ALRs。
识别分数和反应时间数据表明，测试组对某些元音大致熟练（元音/æ/、/e/和/u:/的P <.05），并且在训练6个月后处理时间减少。测试组中，在没有受试者主动参与的情况下，反映中央听觉语音表征的元音变化检测的N1 - P2振幅指标有所增加（P <.05）。
本研究表明在同时进行的语音分离方面有与训练相关的改善。该信息为基于基频（F0）的自下而上训练、其在听觉场景分析中的差异以及神经基础提供了证据。
