In today’s digital age, video content has become essential to every business, organization, or individual’s online presence. However, to make video content accessible to a broader audience, it is crucial to provide accurate subtitles. Subtitles improve the overall user experience and cater to individuals who are deaf or hard of hearing or those who speak a different language. Adding subtitles to videos can be time-consuming and requires human intervention. But with the advent of Amazon Transcribe, a machine learning-powered automatic speech recognition service, creating subtitles has become much more manageable and efficient. This blog will discuss using Amazon Transcribe to create automatic video subtitles.
