Previous research on infant-directed speech (IDS) and its role in infants' language development has largely focused on mothers, with fathers being investigated scarcely. Here we examine the acoustics of IDS as compared to adult-directed speech (ADS) in Norwegian mothers and fathers to 8-month-old infants, and whether these relate to direct…

Parents are often a good source of information, introducing children to how the world around them is described and explained in terms of cause-and-effect relations. Parents also vary in their speech, and these variations can predict children's later language skills. Being born preterm might be related to such parent-child interactions. The present…

This essay describes how an honors classroom introduces public speaking and active listening to encourage heroism and social justice among students. Asserting that people often look for a hero in times of crises, the author suggests that honors programs can become safe places where students learn the skills necessary to advocate for those in need…

Purpose: We sought to establish normative growth curves for intelligibility development for the speech of typically developing children as revealed by objectively based orthographic transcription of elicited single-word and multiword utterances by naïve listeners. We also examined sex differences, and we compared differences between single-word…

The present study aims to explore both native and non-native French speakers' spoken output in two dialogic speaking tasks. More specifically, the aim of this study was threefold. First, the researchers focused on the relationship between L2 learners' receptive and productive vocabulary knowledge and their vocabulary use in two dialogic speaking…

Purpose: This preliminary investigation compared effects of time compression on intelligibility for male versus female talkers. We hypothesized that time compression would have a greater effect for female talkers. Method: Sentence materials from four talkers (two males) were time compressed, and original-speed and time-compressed speech materials…

Objectives: This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared…

We trained a computational model (the Chunk-Based Learner; CBL) on a longitudinal corpus of child-caregiver interactions in English to test whether one proposed statistical learning mechanism--backward transitional probability--is able to predict children's speech productions with stable accuracy throughout the first few years of development. We…

Purpose: In a previous paper (Souza, Wright, Blackburn, Tatman, & Gallun, 2015), we explored the extent to which individuals with sensorineural hearing loss used different cues for speech identification when multiple cues were available. Specifically, some listeners placed the greatest weight on spectral cues (spectral shape and/or formant…

Purpose: Speech production deficits and reduced intelligibility are frequently noted in individuals with Down syndrome (DS) and are attributed to a combination of several factors. This study reports acoustic data on vowel production in young adults with DS and relates these findings to perceptual analysis of speech intelligibility. Method:…

Animals have long been used as comparative models for adult human speech perception. However, few animal models have been used to explore developmental speech perception questions. This dissertation encourages the use of domestic dogs as a behavioral model for speech perception processes. Specifically, dog models are suggested for questions about…

Phonetic imitation is a ubiquitous process in speech production. Speakers have a strong tendency to imitate their interlocutors both in a native and a non-native language. It is especially important in acquiring non-native speech, because it allows forming new sound categories. In the current study we investigated whether and to what extent Polish…

This article aims to identify common errors made by hearing students learning South African Sign Language (SASL) and enhance the understanding of language acquisition in this context. The researchers formulated three hypotheses, attributing errors to vocabulary gaps, misunderstandings due to improper signing, and the dual impact of spoken and…

This study aims to investigate the VOT values of English wordinitial plosive consonants produced by young Thai learners to understand current trends in English pronunciation among Thai speakers and its future direction. The study analyzes how phonological mismatches between Thai and English affect the pronunciation of Thai learners, using a speech…

The assessment of English speaking in EFL environments can be inherently subjective and influenced by various factors beyond linguistic ability, including choice of assessment criteria, and even the rubric type. In classroom assessment, the type of rubric recommended for English speaking tasks is the analytical rubric. Driven by three aims, this…
