在困难的听力条件下，支持语音识别和理解的大脑网络没有得到很好的说明。假设在努力倾听的基础上的网络包括负责执行控制的区域。我们对听觉神经成像研究进行了荟萃分析，以确定额叶的共同激活模式是否支持不同语音操作下的努力听力。研究语音感知的53项功能性神经影像学研究根据使用的语音操作范式类型分为三个独立的激活似然估计分析：噪声语音（SIN， 16项研究，涉及224名参与者）；使用滤波技术的频谱退化语音（涉及270名参与者的15项研究）；语言复杂性（即句法、词汇和语义复杂性/密度水平，22项研究，涉及348名参与者）。SIN研究的荟萃分析显示，较高的努力程度与左侧额下回（IFG）、左侧顶叶下小叶和右侧脑岛的激活有关。使用频谱退化语音的研究表明，双侧脑岛和左侧颞上回（STG）的激活增加。操纵语言复杂性的研究显示左侧IFG、右侧额叶中回、左侧颞中回和双侧STG被激活。计划对比显示，在语言复杂性研究中，左侧IFG被激活，这与在SIN或频谱退化研究中观察到的激活模式不同。虽然这三种语言操作范式的前额叶激活没有明显的重叠，但SIN和频谱退化在左右脑岛显示重叠区域。这些发现提供了证据，表明在左侧IFG和不同的执行网络中存在区域专业化，这是努力倾听的基础。
The brain networks supporting speech identification and comprehension under difficult listening conditions are not well specified. The networks hypothesized to underlie effortful listening include regions responsible for executive control. We conducted meta-analyses of auditory neuroimaging studies to determine whether a common activation pattern of the frontal lobe supports effortful listening under different speech manipulations. Fifty-three functional neuroimaging studies investigating speech perception were divided into three independent Activation Likelihood Estimate analyses based on the type of speech manipulation paradigm used: Speech-in-noise (SIN, 16 studies, involving 224 participants); spectrally degraded speech using filtering techniques (15 studies involving 270 participants); and linguistic complexity (i.e., levels of syntactic, lexical and semantic intricacy/density, 22 studies, involving 348 participants). Meta-analysis of the SIN studies revealed higher effort was associated with activation in left inferior frontal gyrus (IFG), left inferior parietal lobule, and right insula. Studies using spectrally degraded speech demonstrated increased activation of the insula bilaterally and the left superior temporal gyrus (STG). Studies manipulating linguistic complexity showed activation in the left IFG, right middle frontal gyrus, left middle temporal gyrus and bilateral STG. Planned contrasts revealed left IFG activation in linguistic complexity studies, which differed from activation patterns observed in SIN or spectral degradation studies. Although there were no significant overlap in prefrontal activation across these three speech manipulation paradigms, SIN and spectral degradation showed overlapping regions in left and right insula. These findings provide evidence that there is regional specialization within the left IFG and differential executive networks underlie effortful listening.
