Repetition can boost memory and perception. However, repeating the same stimulus several times in immediate succession also induces intriguing perceptual transformations and illusions. Here, we investigate the Speech to Song Transformation (S2ST), a massed repetition effect in the auditory modality, which crosses the boundaries between language and music. In the S2ST, a phrase repeated several times shifts to being heard as sung. To better understand this unique cross-domain transformation, we examined the perceptual determinants of the S2ST, in particular the role of acoustics. In 2 Experiments, the effects of 2 pitch properties and 3 rhythmic properties on the probability and speed of occurrence of the transformation were examined. Results showed that both pitch and rhythmic properties are key features fostering the transformation. However, some properties proved to be more conducive to the S2ST than others. Stable tonal targets that allowed for the perception of a musical melody led more often and quickly to the S2ST than scalar intervals. Recurring durational contrasts arising from segmental grouping favoring a metrical interpretation of the stimulus also facilitated the S2ST. This was, however, not the case for a regular beat structure within and across repetitions. In addition, individual perceptual abilities allowed to predict the likelihood of the S2ST. Overall, the study demonstrated that repetition enables listeners to reinterpret specific prosodic features of spoken utterances in terms of musical structures. The findings underline a tight link between language and music, but they also reveal important differences in communicative functions of prosodic structure in the 2 domains.
重复可以增强记忆和感知。然而，连续多次立即重复相同的刺激也会引发有趣的感知转换和错觉。在这里，我们研究语音到歌曲转换（S2ST），这是一种听觉模态中的集中重复效应，它跨越了语言和音乐之间的界限。在S2ST中，一个短语重复几次后会转变为听起来像歌唱。为了更好地理解这种独特的跨域转换，我们研究了S2ST的感知决定因素，特别是声学的作用。在两个实验中，研究了两种音高属性和三种节奏属性对转换发生概率和速度的影响。结果表明，音高和节奏属性都是促进转换的关键特征。然而，一些属性被证明比其他属性更有利于S2ST。能够让人感知到音乐旋律的稳定音调目标比音阶音程更频繁、更快地导致S2ST。由有利于对刺激进行节拍解释的片段分组产生的反复出现的时长对比也促进了S2ST。然而，在重复过程中和重复之间的规则节拍结构并非如此。此外，个体的感知能力可以预测S2ST的可能性。总体而言，该研究表明，重复使听众能够根据音乐结构重新诠释口语话语的特定韵律特征。这些发现强调了语言和音乐之间的紧密联系，但它们也揭示了这两个领域中韵律结构在交际功能方面的重要差异。
