What is VAST?

VAST is an innovative application of video technology to facilitate and improve communication abilities for speech-impaired individuals. Following close-up video of mouth movements allows these individuals to speak full sentences. The simultaneous combination of visual, auditory and, in some cases, written cues, allows these individuals to readily produce speech. VAST facilitates:

  • live communication and
  • individualized, mobile speech practice.

Most importantly, VAST allows individuals to communicate themselves.
