Speech accessibility and communication aids enable people who are unable to talk, or to talk clearly. These users may have acquired brain damage, autism, cerebral palsy, Down syndrome, intellectual impairment, or strokes. Many speech recognition systems are unable to recognize the speech of these users because they are based on average speakers. Because of the inconsistency of most impaired speech, speaker dependent systems do not have a high rate of accuracy. Speech recognition should not be the only form of input. In addition, some users with impaired speech may have additional motor skills accessibility problems because of impaired dexterity.

Speech accessibility includes difficulties with language and meaning, and difficulty producing intelligible speech. Language and meaning difficulties can also be related to Cognitive impairment. See the tags list below for related resources.
