An illusion is explored in which a spoken phrase is perceptually transformed to sound like song rather than speech, simply by repeating it several times over. In experiment I, subjects listened to ten presentations of the phrase and judged how it sounded on a five-point scale with endpoints marked "exactly like speech" and "exactly like singing." The initial and final presentations of the phrase were identical. When the intervening presentations were also identical, judgments moved solidly from speech to song. However, this did not occur when the intervening phrases were transposed slightly or when the syllables were presented in jumbled orderings. In experiment II, the phrase was presented either once or ten times, and subjects repeated it back as they finally heard it. Following one presentation, the subjects repeated the phrase back as speech; however, following ten presentations they repeated it back as song. The pitch values of the subjects' renditions following ten presentations were closer to those of the original spoken phrase than were the pitch values following a single presentation. Furthermore, the renditions following ten presentations were even closer to a hypothesized representation in terms of a simple tonal melody than they were to the original spoken phrase.
一种错觉被揭示出来，只需将一个短语重复几次，它就能从听起来像说话变成像唱歌。在实验 I 中，被试者听了十遍短语，并在一个五分制的量表上对其进行判断，量表的两端标记为“完全像说话”和“完全像唱歌”。短语的开头和结尾的呈现是相同的。当中间的呈现也相同时，判断从说话到唱歌的转变是稳定的。然而，当中间的短语稍微改变或音节以混乱的顺序呈现时，这种情况就不会发生。在实验 II 中，短语被呈现一次或十次，被试者按照他们最后听到的内容进行复述。在一次呈现后，被试者将短语复述为说话；然而，在十次呈现后，他们将其复述为唱歌。与一次呈现相比，被试者在十次呈现后复述的短语的音高值更接近原始的口语短语。此外，与原始的口语短语相比，十次呈现后的发音在简单的音调旋律方面的假设表现形式甚至更接近。
