The purpose of the present investigation was to determine whether mothers use discernible tunes (i.e., specific interval sequences) in their speech to infants and whether such tunes are individually distinctive. Mothers were recorded speaking with their infants on two occasions separated by 1 week or more. Examination of the tunes of each mother revealed discernible tunes and frequent repetitions of tunes within and across sessions. Comparisons of utterances with the most common pitch contour (i.e., rising), both within and across mothers, revealed interval patterns that were individually distinctive, or unique. The findings confirm the prominence of tunes and the presence of signature tunes in maternal speech to infants.
本研究的目的是确定母亲在与婴儿讲话时是否使用可识别的曲调（即特定的音程序列），以及这些曲调是否具有个体独特性。母亲们在相隔1周或更长时间的两个场合与婴儿交谈时被录音。对每位母亲的曲调进行检查发现了可识别的曲调，并且在各时段内和各时段之间曲调频繁重复。对具有最常见音高轮廓（即上升）的话语在母亲内部和母亲之间进行比较，发现了具有个体独特性或唯一性的音程模式。这些发现证实了曲调在母亲与婴儿讲话中的突出地位以及标志性曲调的存在。
