Pet-directed speech draws adult dogs’ attention more efficiently than Adult-directed speech

Corpus Child Directed Speech Adult Directed Speech

Cross-linguistic studies on unsupervised word segmentation have consistently shown that English is easier to segment than other languages. In this paper, we propose an explanation of this finding based on the notion of segmentation ambiguity. We show that English has a very low segmentation ambiguity compared to Japanese and that this difference correlates with the segmentation performance in a...

The Semantic Spaces of Child-Directed Speech, Child Speech and Adult-directed Speech: A Manifold Perspective

Child-directed speech (CDS) is a talking style adopted by caregivers when they talk to toddlers (Snow, 1995). We consider the role of distributional semantic features of CDS in language acquisition. We view semantic structure as a manifold on which words lie. We compare the semantic structure of verbs in CDS to the semantic structure of child speech (CS) and adult-directed speech (ADS) by measu...

Mature neural responses to Infant-Directed Speech but not Adult-Directed Speech in Pre-Verbal Infants

Infant directed speech (IDS), the speech register adults use when talking to infants, has been shown to have positive effects on attracting infants' attention, language learning, and emotional communication. Here event related potentials (ERPs) are used to investigate the neural coding of IDS and ADS (adult directed speech) as well as their discrimination by both infants and adults. Two instanc...

Statistical properties of infant-directed versus adult-directed speech: insights from speech recognition.

Previous studies have shown that infant-directed speech ('motherese') exhibits overemphasized acoustic properties which may facilitate the acquisition of phonetic categories by infant learners. It has been suggested that the use of infant-directed data for training automatic speech recognition systems might also enhance the automatic learning and discrimination of phonetic categories. This stud...
