ABSTRACT

Although both fathers and mothers speak differently in infant-directed speech (IDS) compared to adult-directed speech (ADS), the acoustic characteristics of present-day paternal IDS are still insufficiently understood. To extend this understanding, 11 fathers and 17 mothers in The Netherlands were recorded interacting with their infant (260–476 days old; for IDS) and with an adult experimenter (for ADS). Both fathers and mothers were found to raise their average pitch, expand their pitch variability within utterance, and increase their pitch variability across utterances in IDS. Moreover, fathers increased their pitch variability within and across utterances more than mothers. The IDS produced by present-day Dutch-speaking fathers is thus acoustically highly dynamic, in line with fathers’ energetic interaction style.

摘要

尽管与成人引导语 (ADS) 相比，父亲和母亲在婴儿引导语 (IDS) 中的说话方式有所不同，但对当今父系 IDS 的声学特征仍知之甚少。为了扩展这种理解，记录了荷兰的 11 位父亲和 17 位母亲与他们的婴儿（260-476 天大；对于 IDS）和与一名成年实验者（对于 ADS）的互动。发现父亲和母亲都提高了他们的平均音调，扩大了话语中的音调可变性，并增加了 IDS 中话语间的音调可变性。此外，与母亲相比，父亲在话语内和话语间的音调可变性增加更多。因此，当今讲荷兰语的父亲制作的 IDS 在声学上具有高度动态性，符合父亲充满活力的互动风格。
