Augmentative and Alternative Communication Centers to Establish National Training Act or the AACCENT Act This bill requires the Department of Health and Human Services to award three grants in geographically diverse regions to establish a network of resource centers to improve access to tools, technologies, strategies, training, and other methods used to supplement or replace speech (i.e., augmentative and alternative communication) for individuals with significant expressive communication disabilities. These are communication disabilities (other than communication disabilities that are primarily visual or auditory in nature) that prevent or significantly limit an individual from understanding or being understood using spoken words, resulting in the need for or benefit from augmentative and alternative communication.
