Still Not Adult-Like: Lexical Stress Contrastivity in Word Productions of Eight- to Eleven-Year-Olds
Peer reviewed Peer reviewed
Direct linkDirect link
Arciuli, Joanne; Ballard, Kirrie J. – Journal of Child Language, 2017
Lexical stress is the contrast between strong and weak syllables within words. Ballard et al. (2012) examined the amount of stress contrastivity across adjacent syllables in word productions of typically developing three- to seven-year-olds and adults. Here, eight- to eleven-year-olds are compared with the adults from Ballard et al. using acoustic…

A Randomized Controlled Trial for Children with Childhood Apraxia of Speech Comparing Rapid Syllable Transition Treatment and the Nuffield Dyspraxia Programme-Third Edition
Peer reviewed Peer reviewed

Murray, Elizabeth; McCabe, Patricia; Ballard, Kirrie J. – Journal of Speech, Language, and Hearing Research, 2015
Purpose: This randomized controlled trial compared the experimental Rapid Syllable Transition (ReST) treatment to the Nuffield Dyspraxia Programme-Third Edition (NDP3; Williams & Stephens, 2004), used widely in clinical practice in Australia and the United Kingdom. Both programs aim to improve speech motor planning/programming for children…

Training Production of Lexical Stress in Typically Developing Children Using Orthographically Biased Stimuli and Principles of Motor Learning
Peer reviewed Peer reviewed

van Rees, Lauren J.; Ballard, Kirrie J.; McCabe, Patricia; Macdonald-D'Silva, Anita G.; Arciuli, Joanne – American Journal of Speech-Language Pathology, 2012
Purpose: Impaired lexical stress production characterizes multiple pediatric speech disorders. Effective remediation strategies are not available, and little is known about the normal process of learning to assign and produce lexical stress. This study examined whether typically developing (TD) children can be trained to produce lexical stress on…

Developmental Trajectory for Production of Prosody: Lexical Stress Contrastivity in Children Ages 3 to 7 Years and in Adults
Peer reviewed Peer reviewed

Ballard, Kirrie J.; Djaja, Danica; Arciuli, Joanne; James, Deborah G. H.; van Doorn, Jan – Journal of Speech, Language, and Hearing Research, 2012
Purpose: Accurate production of lexical stress within English polysyllabic words is critical for intelligibility and is affected in many speech-language disorders. However, models of speech production remain underspecified with regard to lexical stress. In this study, the authors report a large-scale acoustic investigation of lexical stress…

A Treatment for Dysprosody in Childhood Apraxia of Speech
Peer reviewed Peer reviewed
Direct linkDirect link
Ballard, Kirrie J.; Robin, Donald A.; McCabe, Patricia; McDonald, Jeannie – Journal of Speech, Language, and Hearing Research, 2010
Purpose: Dysprosody is considered a core feature of childhood apraxia of speech (CAS), especially impaired production of lexical stress. Few studies have tested the effects of intervention for dysprosody. This Phase II study with 3 children investigated the efficacy of a treatment targeting improved control of relative syllable durations in…

Speech, Prosody, and Voice Characteristics of a Mother and Daughter with a 7;13 Translocation Affecting "FOXP2"
Peer reviewed Peer reviewed

Shriberg, Lawrence D.; Ballard, Kirrie J.; Tomblin, J. Bruce; Duffy, Joseph R.; Odell, Katharine H.; Williams, Charles A. – Journal of Speech, Language, and Hearing Research, 2006
Purpose: The primary goal of this case study was to describe the speech, prosody, and voice characteristics of a mother and daughter with a breakpoint in a balanced 7;13 chromosomal translocation that disrupted the transcription gene, "FOXP2" (cf. J. B. Tomblin et al., 2005). As with affected members of the widely cited KE family, whose…
