本研究调查了母亲在婴儿出生、3个月、6个月、9个月和12个月时对婴儿说的婴儿指向语的音高和交际意图。对母亲（6名女婴和6名男婴）与另一名成年人和她们5岁的婴儿交谈的录音进行了低通过滤，并由60名成年人根据5个量表（积极或消极影响、表达情感、鼓励关注、安慰或抚慰、直接行为）进行评分。平均基频（F-0）和语音音高范围也被测量。与积极情绪相关的话语往往在6个月和12个月时达到峰值，而更指令性的话语在9个月时达到峰值。情感话语的平均F-0随年龄变化，指示话语的音高范围随年龄变化。结果表明，母亲的语言模式反映，补充，并可能促进婴儿的发展。
This study investigated pitch and communicative intent in mothers' infant-directed speech spoken to their infants at birth, 3, 6, 9, and 12 months. Audio recordings of mothers (6 with female, and 6 with male infants) talking to another adult and to their infant at 5 ages were low-pass filtered and rated by 60 adults on 5 scales (Positive or Negative Affect, Express Affection, Encourage Attention, Comfort or Soothe, and Direct Behavior). Mean fundamental frequency (F-0) and pitch range of utterances were also measured. Utterances associated with positive affect tend to peak at 6 and 12 months, whereas more directive utterances peaked at 9 months. Mean F-0 followed the age trend for affective utterances, and pitch range followed the trend for directive utterances. The results suggest mother speech patterns reflect, complement, and perhaps facilitate infant development.
