Rivenez et al. [J. Acoust. Soc. Am. 119 (6), 4027-4040 (2006)] recently demonstrated that an unattended message is able to prime by 28 ms a simultaneously presented attended message when the two messages have a different F0 range. This study asks whether a difference in vocal-tract length between the two messages rather than a difference in F0 can also produce such priming. A priming effect of 13 ms was found when messages were in the same F0 range but had different (15%-30%) vocal-tract length, suggesting that the processing of unattended speech strongly relies on the presence of perceptual grouping cues.
里韦内兹等人[《美国声学学会杂志》119(6)，4027 - 4040(2006)]最近证明，当两条消息具有不同的基频范围时，一条未被注意的消息能够使同时呈现的被注意消息提前28毫秒启动。本研究探讨两条消息之间声道长度的差异而非基频差异是否也能产生这种启动效应。当消息处于相同的基频范围但具有不同(15% - 30%)的声道长度时，发现了13毫秒的启动效应，这表明对未被注意语音的处理强烈依赖于感知分组线索的存在。
