Speech Sound

Research on VR for speech sound differences is at an earlier stage compared to other areas, with most existing work focusing on computer-assisted approaches rather than fully immersive VR. However, the emerging picture is promising.

Technology-assisted speech support tools have been developed for a range of populations, including children with articulation differences, people with childhood apraxia of speech, and adults with motor speech differences following neurological events. These tools typically provide visual feedback on speech production, gamified practice activities, and structured repetition opportunities.

The transition from desktop-based tools to immersive VR is beginning, with researchers exploring how the added engagement and ecological validity of VR could enhance motivation and practice intensity - particularly important for speech sound work, which often requires high-repetition practice over extended periods.

While the evidence base is thinner than for stuttering or social communication, including this area in the research landscape shows the breadth of VR’s potential across the full scope of speech-language practice.
