We examined the relative stability of pitch, tempo, and rhythm in maternal speech and singing to prelinguistic infants. Mothers were recorded speaking and singing to their infants on two occasions separated by 1 week or more. The pitch level and tempo of identical utterances were highly variable across the 1-week period, but these features were virtually unchanged in song repetitions. Rhythmic patterning was largely maintained in speech, as in song. Mothers' accurate reproduction of their sung performances can be considered a form of absolute pitch and absolute tempo.
我们研究了母亲对处于语言前阶段婴儿说话和唱歌时音高、节奏和韵律的相对稳定性。记录了母亲在两次间隔一周或更长时间的情况下对婴儿说话和唱歌的情况。相同话语的音高和节奏在这一周内变化很大，但这些特征在歌曲重复中几乎没有变化。语音中的节奏模式与歌曲中的节奏模式一样，在很大程度上得以保持。母亲对其演唱表演的精确重现可被视为绝对音高和绝对节奏的一种形式。
