Understanding speech in noisy environments is a challenging task that requires sensory and cognitive functions, including memory and auditory attention. Bilinguals and monolinguals have different scores of these abilities. This study aims to investigate the relationship between these cognitive skills and compare Turkish-Persian bilinguals with Persian monolinguals regarding speech-in-noise scores. 45 Turkish-Persian bilinguals and 45 Persian monolinguals, aged 18-25 (mean age 21.67), with normal hearing, participated in a speech in noise, auditory working memory, and auditory attention tests. The bilingual group performed significantly worse than the monolingual group in the quick speech-in-noise and n-back auditory working memory tests ( < 0.05). However, their score on the auditory attention test was better ( < 0.05). Bilinguals showed a significant correlation between auditory working memory, auditory attention, and speech perception in noise. A linear regression validated the proposed model, predicting speech perception scores in noise based on auditory attention and auditory working memory in bilinguals (r2: 0.20, P: 0.008). Research suggests that various cognitive factors impact an individual's ability to perceive speech in noisy environments. Specifically, auditory attention and working memory have different levels of influence on this skill for bilingual individuals.
在嘈杂环境中理解言语是一项具有挑战性的任务，需要感官和认知功能，包括记忆和听觉注意力。双语者和单语者在这些能力方面得分不同。本研究旨在调查这些认知技能之间的关系，并比较土耳其语 - 波斯语双语者和波斯语单语者在噪声环境中言语得分的情况。45名年龄在18 - 25岁（平均年龄21.67岁）、听力正常的土耳其语 - 波斯语双语者和45名波斯语单语者参加了噪声环境中的言语、听觉工作记忆和听觉注意力测试。在快速噪声环境中言语测试和n - 回溯听觉工作记忆测试中，双语组的表现明显比单语组差（<0.05）。然而，他们在听觉注意力测试中的得分更好（<0.05）。双语者在听觉工作记忆、听觉注意力和噪声中的言语感知之间存在显著相关性。线性回归验证了所提出的模型，该模型基于双语者的听觉注意力和听觉工作记忆预测噪声中的言语感知得分（r2：0.20，P：0.008）。研究表明，各种认知因素会影响个体在嘈杂环境中感知言语的能力。具体而言，听觉注意力和工作记忆对双语个体的这项技能有不同程度的影响。
