Synthesized speech intelligibility among native speakers and non-native speakers of English.

Using synthesized and digitized speech in electronic communication devices may greatly benefit individuals who cannot produce intelligible speech. However, multiple investigations have demonstrated that synthesized speech is not always sufficiently intelligible for its listeners. Listening to synthesized speech may be particularly problematic for listeners for whom English is a second language. We compared native and non-native English-speaking adults' listening accuracy for English sentences in natural voice and synthesized voice conditions. Results indicated a disproportionate disadvantage for the non-native English-speaking group when listening to synthesized speech compared to their native English-speaking age peers. There was, however, significant variability in performance within the non-native English group, and this was strongly related to independent measures of English language skill. Specifically, a large portion of the variance in performance on the synthesized speech task was predicted by participants' receptive vocabulary scores.

Synthesized speech intelligibility in sentences: a comparison of monolingual English-speaking and bilingual children.

PURPOSE: Research comparing the intelligibility of human and synthesized speech among both young children and adults has indicated that synthesized speech results in a degrading of intelligibility. The purpose of this study was to compare speech intelligibility of high-probability sentences produced using DECtalk Perfect Paul and live speech among monolingual English-speaking and bilingual children. METHOD: Twenty typically developing children between the ages of 4;5 (years;months) and 6;2 participated. Ten children (6 boys and 4 girls) were monolingual English speakers. The remaining ten children (4 boys and 6 girls) were bilingual. Their reproduction of modeled sentences produced in English via live speech and synthesized speech were analyzed to determine the intelligibility of each speech type. RESULTS: The results indicated that for both groups of children, performance was significantly better in the live speech condition. Results further revealed that the intelligibility decrement for synthesized speech was substantially greater for bilingual speakers. CLINICAL IMPLICATIONS: For bilingual children, even higher quality synthesized speech may present a greater challenge than it does for monolingual English-speaking children. Possible strategies to enhance intelligibility are discussed.

Supporting augmentative and alternative communication use by beginning communicators with severe disabilities.

Augmentative and alternative modes of communication (AAC) have assumed an increasingly important role in meeting the communicative needs of individuals with severe disabilities. Despite the potential of AAC to enhance an individual's communicative effectiveness, practitioners may encounter challenges in implementing AAC interventions with individuals with severe disabilities. This article provides strategies addressing some of the challenges faced by practitioners as they teach beginning communicators with severe disabilities to use AAC. Specifically, this article discusses strategies for dealing with situations when learners (a) have AAC systems but are not using them, (b) have AAC systems but their communication partners are not actively participating, or (c) use alternative, but socially or contextually inappropriate, strategies for communication. This article culminates in a framework for increasing the effectiveness of AAC interventions and presents a discussion of needed research.

Tutorial: teaching communicative rejecting to children with severe disabilities.

Children with severe disabilities typically require systematic instruction to develop their communication abilities. Intervention can begin by teaching functional communication skills related to requesting and rejecting. Although a considerable amount of research has focused on teaching requesting, there is an emerging literature on teaching rejecting. The aim of this tutorial is to review the emerging literature on teaching communicative rejecting to children with severe disabilities. This review considers (a) the definition of communicative rejecting, (b) reasons for teaching communicative rejecting, (c) types of communicative rejecting, and (d) empirically validated strategies for teaching communicative rejecting to children with severe disabilities. The authors include a case study to illustrate the major steps in teaching communicative rejecting to children with severe disabilities.

The impact of aided language stimulation on symbol comprehension and production in children with moderate cognitive disabilities.

Over the past decade, aided language stimulation has emerged as a strategy to promote both symbol comprehension and symbol production among individuals who use graphic mode communication systems. During aided language stimulation, an interventionist points to a graphic symbol while simultaneously producing the corresponding spoken word during natural communicative exchanges. The purpose of this study was to determine the impact of aided language stimulation on children with moderate cognitive disabilities. Three preschool children with moderate cognitive disabilities who were functionally nonspeaking participated in the investigation. The investigator implemented a multiple-probe design across symbol sets/activities. Elicited probes were used to determine whether the children increased their comprehension and production of graphic symbols. Results indicated that all 3 children displayed increased symbol comprehension and production following the implementation of aided language stimulation.
