Although vocalization and mouthing are behaviors frequently performed by infants, little is known about the characteristics of vocalizations that occur with objects, hands, or fingers in infants' mouths. The purpose of this research was to investigate characteristics of vocalizations associated with mouthing in 6- to 9-month-old infants during play with a primary caregiver. Results suggest that mouthing may influence the phonetic characteristics of vocalizations by introducing vocal tract closure and variation in consonant production.
尽管发声和用嘴接触是婴儿经常表现出的行为,但对于婴儿将物体、手或手指放入口中时发出的声音的特征却知之甚少。本研究的目的是调查6至9个月大的婴儿在与主要照顾者玩耍时,与用嘴接触相关的发声特征。结果表明,用嘴接触可能通过引入声道闭合和辅音发音变化来影响发声的语音特征。
