This systematic review aims to evaluate the effectiveness of auditory training (AT) on various parameters, including language abilities, speech perception, auditory behavior, electrophysiological assessments, and working memory, in children with developmental language disorder (DLD) population.
We searched PubMed, Web of Science, EMBASE, MEDLINE, Cochrane Library and CINAHL from inception to August 7, 2023, and further scrutinized the references of all selected articles. We included randomized controlled trials (RCTs) and quasi-experimental studies that investigated the effects of AT on children with DLD. Two researchers independently screened studies, extracted data and assessed risk of bias.
We included nine studies (eight RCTs and one quasi-experimental) in the systematic review, encompassing 379 children with DLD, 195 in the AT group and 184 in the control group. Compared to controls across five studies, AT did not significantly increase language abilities (expressive, receptive and total). Four out of five studies found significant improvements in children's speech perception abilities after AT treatment, particularly phonological awareness and phoneme discrimination. Two studies showed improvements in temporal ordering and figure-context assessment, but two other studies found no significant changes. Two studies examining electrophysiological measures reported increased amplitudes in auditory event-related potentials after AT. Results for phonological working memory were inconsistent, with one study showing improvements in non-word repetition and digit span tasks, while another found no significant changes.
Current evidence does not support the effectiveness of AT in enhancing core language abilities in children with DLD. However, AT may offer potential benefits for specific auditory processing skills and speech perception. More precise evaluation of the effectiveness of AT therapies in this population should be conducted in future research by employing rigorous methodology, bigger sample numbers and standardized outcome measures.

本系统评价旨在评估听觉训练（AT）对发育性语言障碍（DLD）儿童在包括语言能力、言语感知、听觉行为、电生理评估和工作记忆等各项参数上的有效性。
我们检索了从创刊至2023年8月7日的PubMed、科学网、EMBASE、MEDLINE、Cochrane图书馆和CINAHL，并进一步仔细检查了所有入选文章的参考文献。我们纳入了研究AT对DLD儿童影响的随机对照试验（RCT）和准实验研究。两名研究人员独立筛选研究、提取数据并评估偏倚风险。
我们在系统评价中纳入了9项研究（8项RCT和1项准实验），涉及379名DLD儿童，其中195名在AT组，184名在对照组。与五项研究中的对照组相比，AT并未显著提高语言能力（表达、接受和总体语言能力）。五项研究中有四项发现AT治疗后儿童的言语感知能力有显著改善，特别是语音意识和音素辨别能力。两项研究显示时间排序和图形-背景评估有改善，但另外两项研究未发现显著变化。两项检查电生理指标的研究报告称，AT后听觉事件相关电位的振幅增加。语音工作记忆的结果不一致，一项研究显示非单词重复和数字广度任务有改善，而另一项研究未发现显著变化。
目前的证据不支持AT在提高DLD儿童核心语言能力方面的有效性。然而，AT可能对特定的听觉处理技能和言语感知有潜在益处。未来的研究应采用严谨的方法、更大的样本量和标准化的结局指标，对AT疗法在该人群中的有效性进行更精确的评估。
