Child-directed speech has long been known to influence children's vocabulary learning. However, while we know that caregiver utterances differ from those directed at adults in various ways, little is known about any differences in the lexical properties of child-directed and adult-directed utterances. We compare over half a million word tokens…

This study investigated how at-risk kindergarten students respond to the identification of letters and sounds using an embedded picture mnemonic intervention. The problem addressed was that kindergarten students face challenges in developing letter-name knowledge, letter-sound knowledge, and their reciprocal relationship (i.e., grapheme-phoneme…

Reading is an essential skill for daily life and academic success. According to the connectionist model of reading, word recognition involves orthographic, phonological, and semantic processing, as well as the interactions among them. Language skill such as phonological processing, develops earlier than reading acquisition, and thus likely serves…

Background: Previous research has found that high-frequency energy of speech signals decreased while wearing face masks. However, no study has examined the specific spectral characteristics of fricative consonants and vowels and the perception of clarity of speech in mask wearing. Aims: To investigate acoustic-phonetic characteristics of fricative…

Purpose: Vowels and consonants play different roles in language acquisition and speech recognition, yet standard clinical tests do not assess vowel and consonant perception separately. As a result, opportunities for targeted intervention may be lost. This study evaluated closed-set word recognition tests designed to rely predominantly on either…

Purpose: Envelope following responses (EFRs) could be useful for objectively evaluating audibility of speech in children who are unable to participate in routine clinical tests. However, relative to adults, the characteristics of EFRs elicited by frequency-specific speech and their utility in predicting audibility in children are unknown. Method:…

From 2006 the British government strongly favoured synthetic phonics as the principal approach for the teaching of initial literacy in state-funded primary schools in England, and since 2010 has made it mandatory. In 2007-2013 just over 100 commercially published phonics schemes were available, and in that same period the government maintained a…

Purpose: This study aimed to investigate the vocal characteristics of children with cerebral palsy (CP) and anarthria using the stage model of vocal development. Method: Vocal characteristics of 39 children with CP and anarthria around 4 years of age were analyzed from laboratory-based caregiver--child interactions. Perceptual coding analysis was…

Prior research indicates that first language (L1) orthography can adversely affect second language (L2) phonological acquisition, yet studies on orthographic interference and pedagogical strategies to mitigate these effects remain sparse. Addressing these research gaps, this study investigates the impact of orthographic interference on L2 German…

Understanding the early literacy abilities of children who use augmentative and alternative communication (AAC) is essential for designing and testing methods of reading intervention focused on printed orthography. School-based professionals need assessments that measure word reading skills of students with heterogenous speech and physical…

Purpose: This study determined the time course of the emergence of prevocalic stop consonants in young children with cleft palate following surgical repair. Method: A total of 120 children in four cohorts from three institutions were followed from 12 to 24 months of age: (a) 24 with repaired cleft lip and palate (CLP), (b) 36 with repaired cleft…

Speaker's good pronunciation makes his/her listener comfortable, and confident to participate in the conversation and his/her mispronunciations bring implications to the listener's awareness and involvement with the message spoken. The research was aimed at detecting the mispronunciations produced by 70 nonnative (L2) post-graduate students who…

There are contradictory findings in the literature about prosodic sensitivity's contribution to reading. In this study, we examined whether prosodic sensitivity makes a unique contribution to different reading outcomes in German after controlling for the effects of phonological awareness. Word reading, nonword reading and sentence reading as well…

Although children develop categorical speech perception at a very young age, the maturation process remains unclear. A cross-sectional study in Mandarin-speaking 4-, 6-, and 10-year-old children, 14-year-old adolescents, and adults (n = 104, 56 males, all Asians from mainland China) was conducted to investigate the development of categorical…

This study aims to explore and tackle different phenomena of syllable structure and syllabification patterns in Jordanian Arabic (JA). The study compares and contrasts the permissible syllable structures in different Jordanian dialects. It also presents a comprehensive analysis of how speakers of different Jordanian dialects tackle the consonantal…
