Infant-directed speech (IDS) is a specific register that adults use to address infants, and it is characterised by prosodic exaggeration and lexical and syntactic simplification. Several authors have underlined that this simplified speech becomes more complex according to the infant's age. However, there is a lack of studies on lexical and…

This paper reports on an original study designed to investigate age-related change in the way French children produce speech during oral narrative, considering both prosodic parameters -- speaking rate and duration of the prosodic speech unit -- and linguistic structure. Eighty-five French children aged four to eleven years were asked to tell a…

The 24th Annual Graduate Student Conference of the College of Languages, Linguistics & Literature (LLL) at the University of Hawai'i at Manoa was held online on Saturday, April 18th, 2020. This annual conference provides an opportunity for students to become socialized into academic practices, such as presenting at a conference and producing a…

We examine the ability of supervised text classification models to identify several discourse properties from teachers' speech with an eye for providing teachers with meaningful automated feedback about the quality of their classroom discourse. We collected audio recordings from 28 teachers from 10 schools in 164 authentic classroom sessions,…

One of the first challenges facing the young language learner is the task of segmenting words from a natural language speech stream, without prior knowledge of how these words sound. Studies with younger children find that children find it easier to segment words from fluent speech when the words are presented in infant-directed speech, i.e., the…

Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

This study aimed to investigate specific associations between structural and acoustic characteristics of infant-directed (ID) speech and word recognition. Thirty Italian-acquiring children and their mothers were tested when the children were 1;3. Children's word recognition was measured with the looking-while-listening task. Maternal ID speech was…

Two experiments sought to extend the demonstration of English-learning infants' abilities to segment nouns from fluent speech to a new lexical class: verbs. Moreover, we explored whether two factors previously shown to influence noun segmentation, stress pattern (strong-weak or weak-strong) and type of initial phoneme (consonant or vowel), also…

Examines the narrations of several students of one event in order to analyze factors such as suprasegmentals, use of determiners, and verb forms, which contribute to cohesion and coherence in oral narration. (AM)
