SGD Funding Fast Facts
The most general information about SGD funding, useful for anyone considering it for the first time.
SGD or AAC Device?
For funding purposes, the phrases Speech Generating Devices (SGDs), Augmentative and Alternative Communication (AAC) Devices, and Voice Output Communication Aids (VOCA) all refer to the same equipment. The phrase "speech generating devices" (SGDs) was coined by Medicare in 2000.
Demographics and Demand
A conservative estimate is that 0.12 percent (1.2/1,000) of the general population may have an SGD need. However, due to a shortage of qualified Speech-Language Pathologists (SLPs), only 2-3 percent of these individuals are served annually.
Estimated demand: 24-36 per 1,000,000 in the general population.
SGD Medical Need Facts
SGDs are recognized by major medical societies (AMA, AAN, AAPM&R) as effective treatment for severe expressive communication disabilities.
"The medical purpose of SGDs is to treat severe expressive communication impairment that precludes individuals from meeting all daily communication needs using natural communication methods."

The "Functional By-pass"
SGDs serve as a functional by-pass of body parts that are not working due to illness, injury, or disability. This role is identical to the role served by wheelchairs for individuals with mobility impairments.
