直播电视新闻和采访通常包括多个人讲话，具有快速的轮换，这使得聋人和听力困难（DHH）的观众在阅读字幕时难以跟随谁在说话。先前的研究已经提出了几种方法来表明谁在说话。虽然最近的研究已经观察到DHH观众之间的各种偏好的扬声器识别方法的视频与不同数量的扬声器，还没有一项研究，系统地探讨是否有一个正式的关系之间的人数和DHH观众的偏好，如何在字幕中指示扬声器。我们进行了一项实证研究，随后与17名DHH参与者进行了半结构化访谈，以记录他们对不同演讲者数量的视频的各种演讲者标识符类型的偏好。我们观察到DHH观众对说话者识别的偏好与视频中说话者的数量之间存在交互效应。对参与者开放式反馈的分析揭示了影响他们偏好的几个因素。我们的研究结果指导广播公司和字幕选择说话人识别方法的字幕视频。
Live TV news and interviews often include multiple individuals speaking, with rapid turn-taking, which makes it difficult for viewers who are Deaf and Hard of Hearing (DHH) to follow who is speaking when reading captions. Prior research has proposed several methods of indicating who is speaking. While recent studies have observed various preferences among DHH viewers for speaker-identification methods for videos with different numbers of speakers onscreen, there has not yet been a study that has systematically explored whether there is a formal relationship between the number of people onscreen and the preferences among DHH viewers for how to indicate the speaker in captions. We conducted an empirical study followed by a semi-structured interview with 17 DHH participants to record their preferences among various speaker-identifier types for videos that vary in the number of speakers onscreen. We observed an interaction effect between DHH viewers’ preference for speaker identification and the number of speakers in a video. An analysis of open-ended feedback from participants revealed several factors that influenced their preferences. Our findings guide broadcasters and captioners in selecting speaker-identification methods for captioned videos.
