Background: Augmented Reality, initiated in the gaming industry, compensates for hearing deficits through visual information using CROS sensory modality. For the first time, a visual transcript in an AR system enables communicative participation for patient groups that previously relied exclusively on hearing aids, CI systems, or less information-dense forms of communication (sign language).

The aim of this study was to test AR systems and software and to evaluate possible indications and results.

Methods: Four different AR systems with three different software systems were evaluated. The criteria were usability, design, and software variability. Furthermore, the transcript assessment was carried out using the Freiburg monosyllabic test.

Results: The systems differed clearly in their hardware, software, design, and functionality. AR systems enable a significant improvement in communication skills. Freiburg monosyllabic testing increased from 0% to 100% in individual settings.

Conclusion: AR systems offer a significant extension of treatment options for patients with communication disorders due to profound hearing loss.
