Ruth Huntley Bahr is Professor of Communication Sciences and Disorders with a Courtesy appointment in Psychology at the University of South Florida, USA. She is a Fellow of the American Speech-Language-Hearing Association (ASHA), a Fellow of the International Society of Phonetic Sciences (ISPhS), and was awarded the Svend Smith Award for Practical Applications of Phonetics. Her areas of specialization include clinical phonology, voice production, dialectal variations, and prosody. Recent research involves the spelling abilities of typically developing children and dialectal/second language influences on literacy. She is currently serving as the President of ISPhS and Executive Secretary of the International Association of Forensic Phonetics and Acoustics and was past Editor of Language, Speech, and Hearing Services in Schools. Elaine R. Silliman is Professor Emeritus of Communication Sciences and Disorders and Courtesy Professor of Psychology at the University of South Florida, a Fellow of the American Speech-Language-Hearing Association (ASHA), a recipient of the ASHA Honors for her significant scholarly contributions, and a Fellow of the International Association of Research on Learning Disabilities. Her research interests and publications focus on academic language proficiency in children and adolescents who are struggling with reading, writing, and spelling, including monolingual English-speaking children with social dialect variations and bilingual (Spanish-English) children. She is the author or co-author of numerous journal articles and chapters, and a co-editor of eight books, including the Routledge Handbook of Communication Disorders.

"The handbook promises to be a valuable resource for graduate students and researchers in communication disorders." - Choice
