Deaf and Hard-of-Hearing Users' Preferences for Hearing Speakers' Behavior during Technology-Mediated In-Person and Remote Conversations

Various technologies mediate synchronous audio-visual one-on-one communication (SAVOC) between Deaf and Hard-of-Hearing (DHH) and hearing colleagues, including automatic-captioning smartphone apps for in-person settings, or text-chat features of videoconferencing software in remote settings. Speech and nonverbal behaviors of hearing speakers, e.g. speaking too quietly, can make SAVOC difficult for DHH users, but prior work had not examined technology-mediated contexts. In an in-person study (N=20) with an automatic captioning smartphone app, variations in a hearing actor's enunciation and intonation dynamics affected DHH users' satisfaction. In a remote study (N=23) using a videoconferencing platform with text chat, variations in speech rate, voice intensity, enunciation, intonation dynamics, and eye contact led to such differences. This work contributes empirical evidence that specific behaviors of hearing speakers affect the accessibility of technology-mediated SAVOC for DHH users, providing motivation for future work on detecting or encouraging useful communication behaviors among hearing individuals.
