墨西哥西班牙语和美国英语的母语者提出了流交替音节中的元音持续时间和/或吱吱作响的发音有节奏地变化。参与者的分组偏见被测量为他们的行为在分割序列到经常性的双音节单位的函数。结果表明，在这两个语言组的最后一个吱吱分组偏见。持续时间的变化与西班牙语和英语没有一致的趋势，一个弱的长期第一分组偏见。当长的吱吱声和短的模态音节交替出现时，英语组中出现了显著的吱吱声-最后一个音节的偏向，并且没有持续时间的影响。然而，在西班牙组中，观察到的持续时间变化单一的长期第一的趋势被逆转，持续时间和吱吱声的影响是加性的。最后，当短吱吱声和长模态音节交替，持续时间的影响是非常显着的两个语言组（更少吱吱声，更长的最后分组）。在英语中，Creak与高阶韵律域中的最后位置有关，而在西班牙语中则较少。目前的结果表明，英语和西班牙语的发言者可以使用此线索分割成更小的，英尺或单词大小的单位节奏序列。这项研究是第一个建立，吱吱声是西班牙语的人的感知突出，并证明，与持续时间相关的感知可以不同，这取决于它是否是单独或与吱吱声一起变化。更一般地说，目前的研究结果表明，分组效果超出强度，音高和持续时间，最经常操纵的功能在韵律分组研究的启发下抑扬格扬抑律。(C)2017爱思唯尔有限公司版权所有
Native Mexican Spanish and American English speakers were presented with streams of alternating syllables in which vowel duration and/or creaky phonation were rhythmically varied. Participants' grouping biases were measured as a function of their behaviour in segmenting sequences into recurrent bisyllabic units. Results indicated a creak-last grouping bias in both language groups. Duration varied singly was associated with a weak long-first grouping bias for Spanish and no consistent trend for English. When long creaky and short modal syllables were alternated, there was a significant creak-last bias and again no effect of duration in the English group. However, in the Spanish group, the long-first trend observed for duration varied singly was reversed and the effects of duration and creak were additive. Finally, when short creaky and long modal syllables were alternated, duration effects were highly significant in both language groups (fewer creak-last, more long-last groupings). Creak has been associated with final positions in higher-order prosodic domains in English, and less prevalently in Spanish. The current results show that both English and Spanish speakers can use this cue to segment rhythmic sequences into smaller, foot or word-sized units. This study is the first to establish that creak is perceptually salient for Spanish speakers and to demonstrate that the percept associated with duration can differ depending on whether it is varied singly or together with creak. More generally, the current findings show that grouping effects extend beyond intensity, pitch and duration, the features most often manipulated in rhythmic grouping studies inspired by the Iambic Trochaic Law.
