Speech output from speech-generating devices (SGD) and SGD software, such as talking word processors, has changed the landscape of options for aided communication. The purpose of this paper is to review and critique research into the roles of speech output for communication partners, learners, and learner-partner dyads. Research on partner - oriented roles(More)
UNLABELLED Evidence-based practice (EBP) is increasingly being advocated as the preferred approach to practice in augmentative and alternative communication (AAC). The EBP process involves multiple steps. The asking of a well-built question is the first step in the quest for answers. At the same time it is also often the first stumbling block for(More)
UNLABELLED Evaluation of client progress is an important topic in communicative disorders research and clinical literature. Goal attainment scaling (GAS) is a technique for evaluating individual progress toward goals. Despite recognition of GAS as a clinical-outcome assessment technique in other clinical professions, the current debate on measuring client(More)
PURPOSE This systematic review aimed to determine the effects of augmentative and alternative communication (AAC) intervention on speech production in children with autism or pervasive developmental disorder-not otherwise specified. METHOD A systematic review methodology was utilized to limit bias in searching, selecting, coding, and synthesizing relevant(More)
Matrix strategies employing parts of speech arranged in systematic language matrices and milieu language teaching strategies have been successfully used to teach word combining skills to children who have cognitive disabilities and some functional speech. The present study investigated the acquisition and generalized production of two-term semantic(More)
The burgeoning role of technology in society has provided opportunities for the development of new means of communication for individuals with Autism Spectrum Disorders (ASD). This paper offers an organizational framework for describing traditional and emerging augmentative and alternative communication (AAC) technology, and highlights how tools within this(More)
Students with developmental disabilities and limited or no functional speech often use speech-generating devices. While the speech-output function of such devices is considered to have potential advantages, it is unclear whether the length of synthetic speech output influences augmented communication and natural speech production. To this end, we describe a(More)
PURPOSE This article presents the results of a meta-analysis to determine the effect of augmentative and alternative communication (AAC) on the speech production of individuals with developmental disabilities. METHOD A comprehensive search of the literature published between 1975 and 2003, which included data on speech production before, during, and after(More)
Two students with developmental disabilities were taught to request six snack items. Requesting involved giving a graphic symbol to the trainer in exchange for the matching snack item. Following acquisition, we assessed the correspondence between requests and subsequent item selections by requiring the student to select the previously requested snack item(More)
