Methods: We assessed speech perception using standardized test material presented under simulated VoIP conditions with increasing digital data packet loss (from 0{\%} to 20{\%}) and compared with simulated ideal conventional telephone quality. We monaurally tested 10 adult users of cochlear implants, 10 adult users of hearing aids, and 10 normal-hearing adults in the free sound field, both in quiet and with background noise. Results: Across all participant groups, mean speech perception scores using VoIP with 0{\%}, 5{\%}, and 10{\%} packet loss were 15.2{\%} (range 0{\%}--53{\%}), 10.6{\%} (4{\%}--46{\%}), and 8.8{\%} (7{\%}--33{\%}) higher, respectively, than with ideal conventional telephone quality. Speech perception did not differ between VoIP with 20{\%} packet loss and conventional telephone quality. The maximum benefits were observed under ideal VoIP conditions without packet loss and were 36{\%} (P = .001) for cochlear implant users, 18{\%} (P = .002) for hearing aid users, and 53{\%} (P = .001) for normal-hearing adults. With a packet loss of 10{\%}, the maximum benefits were 30{\%} (P = .002) for cochlear implant users, 6{\%} (P = .38) for hearing aid users, and 33{\%} (P = .002) for normal-hearing adults. Conclusions: VoIP offers a speech perception benefit over conventional telephone quality, even when mild or moderate packet loss scenarios are created in the laboratory. VoIP, therefore, has the potential to significantly improve telecommunication abilities for the large community of hearing-impaired individuals.
