Book Description
The differential diagnosis of developmental language disorder (DLD) in bilingual children represents a unique challenge due to their distributed language exposure and knowledge. The current evidence indicates that dual-language testing yields the most accurate classification of DLD among bilinguals, but there are limited personnel and resources to support this practice. This study explored the feasibility of dual-language automatic speech recognition (ASR) for identifying DLD in bilingual children. Eighty-four Spanish-English bilingual second graders with (n = 25) and without (n = 59) confirmed diagnoses of DLD completed the Bilingual English-Spanish Assessment - Middle Extension (BESA-ME) Morphosyntax in both languages. Their responses on a subset of items were scored manually by human examiners and programmatically by a researcher-developed ASR application employing a commercial speech-to-text algorithm. Results demonstrated moderate overall item-by-item scoring agreement (k = 0.54) and similar diagnostic accuracies (human = 92%, ASR = 88%) between the two methods using the best-language score. Classification accuracy of the ASR method increased to 94% of cases correctly classified when test items with poorer discrimination in the ASR condition were eliminated. These findings establish the concurrent validity of the BESA-ME Morphosyntax for Spanish-English bilingual second graders when ASR is used to process their responses. More broadly, this study provides preliminary support for the technical feasibility of ASR as a bilingual expressive language assessment tool

Book Description
During the last years a significant number of papers, books, and monographs devoted to speech and language impairments in bilingual children have been published. Different aspects and questions have been approached and today we have a relatively good understanding of the specific characteristics of the speech and language difficulties potentially observed in bilingual and multilingual children. This interest has been significantly resulted from the potential developmental and educational consequences of bilingualism. Our understanding of the communication disorders in adult populations is notoriously more limited, even though over 50% of the adult population can speak at least another language in addition to his/her native language. That simply means that over 50% of the communication disorders observed in adults are bilingual speech and language disorders: bilingual aphasias, bilingual dementias, bilingual stuttering, etc. This book was written with the specific purpose of filling this gap. The major purpose of this book has been to integrate the state of the art on the different aspects of the communication disorders observed in adult bilinguals. The book is organised in such a way that an integrated perspective of bilingualism is presented: from the normal conditions to the pathology; from the clinical descriptions to the rehabilitation issues; from the biological factors to the cultural variables.

Book Description
"Language Disorders in Bilingual Children and Adults, Third Edition, provides speech-language pathologists, advanced students in communication disorders programs, and clinical language researchers with information needed to formulate and respond to questions related to effective service delivery to bilingual children and adults with suspected or confirmed language disorders. The bilinguals of interest represent varying levels of first and second language proficiency across the lifespan. That is, bilingualism is not determined here by proficiency in each language, but rather by the individual's experience or need for two languages"--

Book Description
Prominent researchers from the US, Mexico, Chile, Colombia and Spain contribute experimental reports on language development of children who are acquiring Spanish. The chapters cover a wide range of dimensions in acquisition: comprehension and production; monolingualism and bilingualism; typical development, children who are at risk and children with language disorders, phonology, semantics, and morphosyntax. These studies will inform linguistic theory development in clinical linguistics as well as offer insights on how language works in relation to cognitive functions that are associated with when children understand or use language. The unique data from child language offer perspectives that cannot be drawn from adult language. The first part is dedicated to the acquisition of Spanish as a first or second language by typically-developing children, the second part offers studies on children who are at risk of language delays, and the third part focuses on children with specific language impairment, disorders and syndromes.

Book Description
Code-switching - the alternating use of two languages in the same stretch of discourse by a bilingual speaker - is a dominant topic in the study of bilingualism and a phenomenon that generates a great deal of pointed discussion in the public domain. This handbook provides the most comprehensive guide to this bilingual phenomenon to date. Drawing on empirical data from a wide range of language pairings, the leading researchers in the study of bilingualism examine the linguistic, social and cognitive implications of code-switching in up-to-date and accessible survey chapters. The Cambridge Handbook of Linguistic Code-switching will serve as a vital resource for advanced undergraduate and graduate students, as a wide-ranging overview for linguists, psychologists and speech scientists and as an informative guide for educators interested in bilingual speech practices.

Book Description
Both SLPs and researchers must understand speech and language developments in children - and SLPs also need reliable assessment and intervention approaches for serving bilingual children with language disorders. This comprehensive text is one of the few to offer readers in-depth theoretical and practical information on these timely topics. brings together more than a dozen top researchers to present developmental data, best assessment practices, and appropriate intervention approaches in the following areas: language processing skills; lexical development; morpho-syntactic development; first language loss; grammatical impairments; semantic development; phonological development and disorders; narrative development and disorders; fluency; language intervention for bilingual speakers. The chapter outlines the major purposes of intervention for bilingual children with speech and language disorders, explores the debate over which language SLPs should use with bilingual children, and examines ways to promote gains in both languages. With this research-based text, SLPs will understand the complexity of language development in bilingual children and learn appropriate assessment and intervention approaches.
