closed captioning
实时将语音及关键音频转写为屏幕文字的无障碍功能，常被集成到虚拟协作工具中以支持听障参与者参与会议与协作。
English Definition
"On-screen text that transcribes spoken dialogue and relevant audio in real time, an accessibility feature commonly integrated into virtual collaboration tools to support deaf and hard-of-hearing participants."
用法说明 · 针对中文母语者
中文常译为'隐藏式字幕'或'实时字幕'。与普通字幕 (subtitles) 区别在于 closed captioning 还包含对环境音、音乐等非语音声音的描述。
常见错误
- ·易把 closed captioning 与 open subtitles 混用；'closed' 在技术上指用户可选择性开关的字幕轨。
- ·易忽略 captioning 在混合会议中也会出错，文献明确把它列为无障碍障碍之一。
