An intern has developed a way of editing captions within YouTube, drastically increasing the quality of auto-generated captions across the video sharing service.

To provide captions on their YouTube videos, users can either upload their own caption files or use the 'machine transcript' function to generate automatic captions through Google’s voice recognition technology.  These are automatically generated with time codes and appear as captions on the videos once they are turned on. However, the auto-generated captions are renowned for their inaccuracy.

YouTube captions boost SEO

no

Adding captions to a YouTube video can improve your search engine optimisation and increase your audience to include the Deaf and hearing impaired, those learning English and those wishing to view your video without sound (e.g. in a noisy or busy environment).

By captioning your YouTube video, Google can index not only the title, description and tags of your YouTube video, but also the video content. This increases your search ranking, and the likelihood that your video will appear higher in Google and YouTube search results. This also results in more relevant ads in YouTube videos.
