互联网上视频和音频媒体的激增给聋人互联网用户带来了明显的不利条件。尽管近几十年来在使电视和电影更容易访问方面取得了技术和立法里程碑，但在线访问方面的进展却较少。为互联网媒体提供字幕的一个主要障碍是字幕和转录服务的高昂成本。本文报道了两项研究，重点关注先天聋哑或自幼聋哑的互联网用户的多媒体可访问性。一项初步研究试图确定改善聋人无障碍环境的优先事项。通过视频电话采访了总共 20 名聋人和听力障碍参与者，了解他们的互联网使用情况以及最令人沮丧的问题。最常见的主题是对缺乏在线新闻的可访问性的担忧。在第二项研究中，共有 95 名失聪和听力障碍参与者评估了不同的字幕样式，其中一些是通过自动语音识别生成的。第二项研究的结果证实，即使字幕是自动生成的，为在线视频添加字幕也能让聋哑用户更容易访问互联网。然而，用于突出置信水平的颜色编码标题被发现既没有好处也没有坏处；然而，当直接被问及颜色编码的好处时，参与者强烈支持这个概念。
The proliferation of video and audio media on the Internet has created a distinct disadvantage for deaf Internet users. Despite technological and legislative milestones in recent decades in making television and movies more accessible, there has been less progress with online access. A major obstacle to providing captions for Internet media is the high cost of captioning and transcribing services. This paper reports on two studies that focused on multimedia accessibility for Internet users who were born deaf or became deaf at an early age. An initial study attempted to identify priorities for deaf accessibility improvement. A total of 20 deaf and hard-of-hearing participants were interviewed via videophone about their Internet usage and the issues that were the most frustrating. The most common theme was concern over a lack of accessibility for online news. In the second study, a total of 95 deaf and hard-of-hearing participants evaluated different caption styles, some of which were generated through automatic speech recognition. Results from the second study confirm that captioning online videos makes the Internet more accessible to the deaf users, even when the captions are automatically generated. However color-coded captions used to highlight confidence levels were found neither to be beneficial nor detrimental; yet when asked directly about the benefit of color-coding, participants strongly favored the concept.
