Video Assisted Speech Technology to Enhance Functional Language Abilities in Individuals With Autism Spectrum Disorder
Video Assisted Speech Technology to Enhance Functional Language Abilities in Individuals With Autism Spectrum Disorder
Nearly 3.5 million Americans are diagnosed with Autistic Spectrum Disorder (ASD), a communication disorder that causes skill limitations in the areas of language acquisition, sensory integration, and behavior. This lack of functional language ability limits conversation to its most basic parts, making daily tasks difficult for minimally to non-verbal individuals to achieve. iTherapy is developing the VAST platform, a personalized educational experience for students with ASD by creating a virtual reality-based video-modeling program to stimulate engagement and speech production practice, ultimately providing those with ASD an opportunity to enhance their quality of life by increasing their speech abilities which will enable them to build social networks and handle the events of daily life.
Autism Spectrum Disorder (ASD) is a neurodevelopmental communication disorder resulting in functional language and behavioral delays affecting over 3.5 million Americans. These delays vary with the severity of symptoms that present in ASD but often result in limited speech and increased communication challenges. Alongside linguistic acquisition, oral motor coordination is a crucial part of speech production.
Current clinical techniques have shown varying degrees of efficacy in improving functional language proficiency. Most techniques follow a drill-like procedure, where the child is made to repeat various sounds and phrases until they are retained. However, such a process requires potentially over twenty therapy sessions to show improvement which may then only be focused on one aspect of speech. This significantly limits the linguistic and social skills a student will acquire. To improve the efficacy of these therapy sessions, new technology must be developed to provide the most effective educational experience.
Video-assisted speech technology (VAST) is a method of using a video of a close-up model of the mouth and speaking simultaneously with it. Rather than present the individual with a static photograph of the initial phoneme, the entire sequence of oral movements can be presented sequentially via video-recorded segments of the orofacial area producing connected speech, combining best practices, video modeling, and literacy with auditory cues to provide unprecedented support the development of vocabulary, word combinations and communication.
In this SBIR Phase I proposal, iTherapy will develop a personalized educational experience for students with ASD by creating a virtual reality (VR) based VAST program to stimulate engagement and speech production practice. VR offers several benefits as a therapy technique: overcoming sensory difficulties, more effectively generalizing information, employing visual learning, and providing individualized treatment. As a user moves through the stages of the program, they will be immersed in a proactive environment where they will engross themselves with continuous content.
Rather than present the individual with a static photograph of the initial phoneme, the entire sequence of oral movements can be presented sequentially via VR-modelled segments of the orofacial area producing connected speech, combining best practices, video modeling, music therapy, and literacy with auditory cues to provide unprecedented support the development of vocabulary, word combinations and communication. The innovation will be a video series of a realistic VR mouth which will require the use of an app on a tablet or a smartphone, VR goggles, and bone conduction headphones.
