为了理解口语，听众必须适当地解释共同出现的说话者特征和语音内容。这种能力在6到14个月大的婴儿中进行了测试，通过测量他们对命名食物和身体部位图像的期待。在新的说话者条件下（n=90），图片由不熟悉的声音命名;在错误发音条件下（n=98），婴儿的母亲错误发音的话（例如，nazz for nose）。6到7个月大的婴儿在各种条件下都能将目标图像固定在机会之上，理解新奇的谈话者，以及母亲的语音异常语音。11到14个月大的婴儿也能理解新说话的人，但在发音错误的情况下表现不佳，这表明他们对语音偏差很敏感。在这些年龄段之间，表现好坏参半。这些发现强调了声音和语音变异在早期单词理解中不断变化的作用，因为婴儿学习哪些变化会改变含义。
To understand spoken words, listeners must appropriately interpret co-occurring talker characteristics and speech sound content. This ability was tested in 6- to 14-months-olds by measuring their looking to named food and body part images. In the new talker condition (n=90), pictures were named by an unfamiliar voice; in the mispronunciation condition (n=98), infants' mothers mispronounced the words (e.g., nazz for nose). Six- to 7-month-olds fixated target images above chance across conditions, understanding novel talkers, and mothers' phonologically deviant speech equally. Eleven- to 14-months-olds also understood new talkers, but performed poorly with mispronounced speech, indicating sensitivity to phonological deviation. Between these ages, performance was mixed. These findings highlight the changing roles of acoustic and phonetic variability in early word comprehension, as infants learn which variations alter meaning.
