使用普通话这种“声调语言”，用音节的音高轮廓来区分单词，作者在音节水平上检查了婴儿指向语（IDS）的声学变化，以检验两个假设：(a)婴儿指向语在短语水平上发生的音高和语调轮廓的整体增加不会扭曲音节水平上的词汇音高；(b)婴儿指向语提供了夸大词汇音调的线索。16位讲普通话的母亲在称呼婴儿和称呼成年人时被记录下来。结果表明，语音识别不会在音节水平上扭曲对单词意义至关重要的声音线索；在IDS中观察到的声学差异夸大的证据，将先前的语音夸大的发现扩展到词汇水平。
Using Mandarin Chinese, a "tone language" in which the pitch contours of syllables differentiate words, the authors examined the acoustic modifications of infant-directed speech (IDS) at the syllable level to test 2 hypotheses: (a) the overall increase in pitch and intonation contour that occurs in IDS at the phrase level would not distort lexical pitch at the syllable level and (b) IDS provides exaggerates cues to lexical tones. Sixteen Mandarin-speaking mothers were recorded while addressing their infants and addressing an adult. The results indicate that IDS does not distort the acoustic cues that are essential to word meaning at the syllable level; evidence of exaggeration of the acoustic differences in IDS was observed, extending previous findings of phonetic exaggeration to the lexical level.
