Abstract
Individuals who use augmentative and alternative communication (AAC) depend on technology to meet their daily needs and form relationships. Speech generating devices (SGDs) are integral components of communication systems. Reliability of SGDs is critical for effective use in everyday life. This study examined the reliability of new SGDs and found that mean time to first failure was 42.7 (SD = 41.2) weeks and at least 40% required repairs within the first year of use. The components that most frequently broke down were touch screens, wiring, main boards, batteries, memory cards, and AC adaptors. The costs of repairing SGDs were analyzed. The clinical implications of device breakdown are identified for key stakeholders, including clients, families, service providers, funding agencies, and manufacturers.
