One characteristic of infant-directed speech is that it is highly fluent compared with adult-directed speech. However, the speech that infants hear still contains disfluencies. Such disfluencies might potentially cause problems for infants during language development. We first analyzed samples of spontaneous speech in the presence of infants (both adultand infant-directed) and found that under ...

The onset of literacy marks a significant change in children’s development. Written language is more complex than everyday conversation, and even books targeted at preschoolers contain varied words syntax child-directed speech does. We review the nature content book language, focusing on recent large-scale corpus analyses that systematically compared written spoken language. argue exposure to p...

 Abstract Background: The aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (CI) on speech intelligibility. Methods: Aprospective study was undertaken on 47 children in a pediatric tertiary referral center for CI. All children were deaf prelingually and were younger than 8 years of age. They were followed up until 5...

Infants learn language at an incredible speed, and one of the first steps in this voyage is learning the basic sound units of their native languages. It is widely thought that caregivers facilitate this task by hyperarticulating when speaking to their infants. Using state-of-the-art speech technology, we addressed this key theoretical question: Are sound categories clearer in infant-directed sp...

In this work, we examine a context in which a conflict arises between two roles that infant-directed speech (IDS) plays: making language structure salient and modeling the adult form of a language. Vowel devoicing in fluent adult Japanese creates violations of the canonical Japanese consonant-vowel word structure pattern by systematically devoicing particular vowels, yielding surface consonant ...

Purpose Most educational assessments tend to be constructed in a close-ended format, which is easier score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences make open-ended measurement effective reliable for older students. The purpose of this study determine whether models used by computational mining applications need a...
