先前的电生理学研究已经确定了“语音特异性反应”（VSR）在刺激开始后约320 ms达到峰值，该潜伏期明显长于区分活体和非活体声源所需的70 ms和处理语音语言质量所需的150 ms至200 ms。在本研究中，我们调查是否可以观察到语音和非语音刺激之间的早期电生理差异。32名健康志愿者在进行纯音检测任务的同时，听了200 ms长的三种声音类别的刺激-声音，鸟鸣和环境声音-记录了ERP。ERP分析显示，语音/非语音振幅差异出现早在164毫秒后刺激发作和峰值约200毫秒的额颞（阳性）和枕（阴性）电极。我们的电生理结果表明，一个快速的声音的声音，被称为“额颞积极的声音”（FTPV）的大脑歧视，在lasting与著名的脸优先N170。
Previous electrophysiological studies have identified a "voice specific response" (VSR) peaking around 320 ms after stimulus onset, a latency markedly longer than the 70 ms needed to discriminate living from non-living sound sources and the 150 ms to 200 ms needed for the processing of voice paralinguistic qualities. In the present study, we investigated whether an early electrophysiological difference between voice and non-voice stimuli could be observed. ERPs were recorded from 32 healthy volunteers who listened to 200 ms long stimuli from three sound categories - voices, bird songs and environmental sounds - whilst performing a pure-tone detection task. ERP analyses revealed voice/non-voice amplitude differences emerging as early as 164 ms post stimulus onset and peaking around 200 ms on fronto-temporal (positivity) and occipital (negativity) electrodes. Our electrophysiological results suggest a rapid brain discrimination of sounds of voice, termed the "fronto-temporal positivity to voices" (FTPV), at latencies comparable to the well-known face-preferential N170.
