Internet video telephony allows speech reading by deaf individuals and improves speech perception by cochlear implant users.

<h4>Objective</h4>To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI) users.<h4>Methods</h4>Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM) sent...

We presented video simulations using different video resolutions (1280 × 720, 640 × 480, 320 × 240, 160 × 120 px), frame rates (30, 20, 10, 7, 5 frames per second (fps)), speech velocities (three different speakers), webcameras (Logitech Pro9000, C600 and C500) and image/sound delays (0-500 ms). All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed.<h4>Results</h4>Higher frame rate (>7 fps), higher camera resolution (>640 × 480 px) and shorter picture/sound delay (<100 ms) were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009) in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11) showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032).<h4>Conclusion</h4>Webcameras have the potential to improve telecommunication of hearing-impaired individuals.Georgios MantokoudisClaudia DählerPatrick DubachMartin KompisMarco D CaversaccioPascal SennPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 8, Iss 1, p e54770 (2013)
