The Temporal Voice Areas (TVAs) respond more strongly to speech sounds than to non-speech vocal sounds, but does this make them Temporal "Speech" Areas? We provide a perspective on this issue by combining univariate, multivariate, and representational similarity analyses of fMRI activations to a balanced set of speech and non-speech vocal sounds. We find that while speech sounds activate the TVAs more than non-speech vocal sounds, which is likely related to their larger temporal modulations in syllabic rate, they do not appear to activate additional areas nor are they segregated from the non-speech vocal sounds when their higher activation is controlled. It seems safe, then, to continue calling these regions the Temporal Voice Areas.
颞叶语音区(TVAs)对语音的反应比对非语音发声更强烈,但这就能称它们为颞叶“语音”区吗?我们通过对功能磁共振成像(fMRI)激活进行单变量、多变量和表征相似性分析,以一组平衡的语音和非语音发声来探讨这个问题。我们发现,虽然语音比非语音发声更能激活TVAs,这可能与它们在音节速率上更大的时间调制有关,但当控制其较高的激活水平时,它们似乎并没有激活额外的区域,也没有与非语音发声区分开来。那么,继续将这些区域称为颞叶语音区似乎是合理的。
