    "abstract": "This study investigated how caregivers modulate their\nspeaking rate according to children’s lexical knowledge and\nthe context of the interaction, and how such adjustments\naffect children’s word learning. We studied a semi-\nnaturalistic corpus where caregivers talked about different\ntoys with their 3-4 years old children. The toys were known\nor unknown to the child, and present or absent from the\nenvironment. We found that caregivers talked about\nunknown toys with a slower speaking rate than known ones.\nWhen toys were absent, caregivers also tended to slow down\nfor the toy’s name, although they produced the whole\nutterance faster. Crucially, the results of a subsequent\nrecognition task for children showed that caregivers’ greater\nadjustment in speaking rate between known and unknown\nwords predicted better immediate learning. Our findings\nsuggest that caregivers modify their speaking rate in a\nhelpful manner when the situation is more demanding,\nwhich assists children in word learnin",
