Previous research has suggested that the direction of short-duration fundamental frequency (F0) perturbations following consonants helps to signal consonant [+voice]/[-voice] (abbreviated as [voice]) status. It has been proposed that the [voice] cue corresponds to the direction and extent of F0 perturbations relative to the overall intonation contour. A competing view, the low-frequency hypothesis, suggests that F0 participates in a more general way whereby low-frequency energy near the consonant contributes to [+voice] judgments. Listeners identified multiple stimulus series, each varying in voice onset time and ranging from /aga/ to /aka/. The series differed in overall intonation contour as well as in the direction of F0 perturbation relative to that contour. Consistent with one version of the low-frequency hypothesis, the F0 value at voicing onset, rather than the relative direction of the F0 perturbation, was the best predictor of [voice] judgments.
先前的研究表明，辅音之后短时长基频（F0）扰动的方向有助于指示辅音的[+浊音]/[-浊音]（简称为[浊音]）状态。有人提出，[浊音]线索对应于F0扰动相对于整体语调轮廓的方向和程度。一种与之竞争的观点，即低频假说，认为F0以一种更普遍的方式参与其中，即辅音附近的低频能量有助于做出[+浊音]判断。听众识别了多个刺激序列，每个序列的语音起始时间不同，范围从/aga/到/aka/。这些序列在整体语调轮廓以及F0扰动相对于该轮廓的方向上都有所不同。与低频假说的一个版本一致，发声起始时的F0值而非F0扰动的相对方向是[浊音]判断的最佳预测指标。
