Abstract

Previous brain imaging results indicated that speech perception proceeded independently of the auditory primitives that are the product of primary auditory cortex [Whalen, Benson, Richardson, Swainson, Clark, Lai, Mencl, Fulbright, Constable, and Liberman (2006). J. Acoust. Soc. Am. 119, 575-581]. Recent evidence using electrocorticography [Hamilton, Oganian, Hall, and Chang (2021). Cell 184, 4626-4639] indicates that there is a more direct connection from subcortical regions to cortical speech regions than previous studies had shown. Although the mechanism differs, the Hamilton, Oganian, Hall, and Chang result supports the original conclusion even more strongly: Speech perception does not rely on the analysis of primitives from auditory analysis. Rather, the speech signal is processed as speech from the beginning.

摘要

先前的脑成像研究结果表明,言语感知独立于初级听觉皮层产生的听觉基本元素[Whalen、Benson、Richardson、Swainson、Clark、Lai、Mencl、Fulbright、Constable 和 Liberman(2006)。J. Acoust. Soc. Am. 119, 575-581]。最近使用皮质电图的证据[Hamilton、Oganian、Hall 和 Chang(2021)。Cell 184, 4626-4639]表明,与之前的研究相比,从皮质下区域到皮质言语区域的连接更为直接。尽管机制不同,但 Hamilton、Oganian、Hall 和 Chang 的研究结果更有力地支持了最初的结论:言语感知不依赖于听觉分析的基本元素分析。相反,语音信号从一开始就被当作语音进行处理。
