Metrics for comparing three word-based software programs used for augmentative and alternative communication.

The purpose of this investigation was to conduct an analysis of a set of metrics developed for comparing features of software used in speech generating devices (SGD) for augmentative and alternative communication (AAC). These metrics - measures of speed, efficiency, and accuracy - were employed during a sentence reconstruction task. Twenty two participants without disabilities reconstructed nine sentences using each of three SGD software programs, counterbalanced to remove order effects. Results revealed differences in the metrics across the software programs that were supported by a social validation survey completed by the participants. These results provide benchmark data about relative speed, accuracy, and efficiency of these software programs in structured use, and can inform professionals in matching potential AAC users with specific features of word-based software.

Preparation in augmentative and alternative communication: an update for speech-language pathology training.

PURPOSE: To report on data from the current survey about academic and clinical education in augmentative and alternative communication (AAC), as well as to compare these findings with earlier surveys in an attempt to identify any changes being made as programs in the United States implement the new certification standards of the American Speech-Language-Hearing Association in the area of speech-language pathology. METHOD: A survey was sent to all speech-language pathology training programs in the United States via e-mail directed to program directors or faculty teaching in AAC. RESULTS: A total of 168 surveys were returned, for a return rate of 57.93%. Seventy-three percent of the respondents had a separate course in AAC, and 80% indicated AAC content was infused in other courses. CONCLUSIONS: Academic preparation in AAC, while varying across academic programs, has in general increased over the past decade. Data also suggested a continuing critical need for more academic and clinical preparation in this area.
