除了其他复杂的声音外，大脑的几个周边区显示出对口语的优先激活。这些“语音选择性”效应可能是由不同区域在处理语音的声学或信息特性时的内在偏向所驱动的。或者，这种语音选择性可能是通过感知和产生语音的丰富经验而出现的。这项功能磁共振成像(FMRI)研究通过比较女性职业小提琴家和演员在听演讲和听音乐时的激活，消除了这种听觉运动专长与言语选择性的歧义。听觉运动特长效应在几个左右上颞区被识别，这些区域对所有参与者的讲话和小提琴手的音乐比女演员更有反应。在所有参与者中，与语音的声学/信息内容相关的区域沿着双侧上颞沟的整个长度被识别，其中语音的激活程度大于音乐。最后，在通常由手指和嘴巴运动激活的双侧运动前区域以及右脑的“语言区域”中，确定了表演艺术训练的效果。这些结果区分了看似语音特有的神经反应，这些反应可以被长期的听觉运动经验废除，甚至逆转。
Several perisylvian brain regions show preferential activation for spoken language above and beyond other complex sounds. These “speech-selective” effects might be driven by regions’ intrinsic biases for processing the acoustical or informational properties of speech. Alternatively, such speech selectivity might emerge through extensive experience in perceiving and producing speech sounds. This functional magnetic resonance imaging (fMRI) study disambiguated such audiomotor expertise from speech selectivity by comparing activation for listening to speech and music in female professional violinists and actors. Audiomotor expertise effects were identified in several right and left superior temporal regions that responded to speech in all participants and music in violinists more than actresses. Regions associated with the acoustic/information content of speech were identified along the entire length of the superior temporal sulci bilaterally where activation was greater for speech than music in all participants. Finally, an effect of performing arts training was identified in bilateral premotor regions commonly activated by finger and mouth movements as well as in right hemisphere “language regions.” These results distinguish the seemingly speech-specific neural responses that can be abolished and even reversed by long-term audiomotor experience.
