AUTOMATICALLY CAPTIONING AUDIBLE PARTS OF CONTENT ON A COMPUTING DEVICE

A computing device is described for automatically captioning content. The computing device generates captions directly from audio data being output from content sources, unlike other captioning systems which often rely on information contained in audio signals being sent to speakers. The computing device may analyze metadata to determine whether the audio data is suitable for captioning or whether the audio data is some other type of audio data. Responsive to identifying audio data for captioning, the computing device can quickly generate a description of audible sounds interpreted from the audio data. The computing device can provide the descriptions of audible content visually no matter the application source of the audible content and regardless whether the computing device ever produces audio of the content. 描述了一种用于对内容自动加字幕的计算设备。与通常依赖于正被发送给扬声器的音频信号中包含的信息的其他加字幕系统不同，该计算设备直接从正从内容源输出的音频数据中生成字幕。计算设备可以分析元数据以确定音频数据是否适合于加字幕或音频数据是否是某个其他类型的音频数据。响应于识别用于加字幕的音频数据，计算设备可以快速生成从音频数据中解释的可听声音的描述。无论可听内容的应用源如何并且不管计算设备是否曾经产生该内
