What Is Subtitle Generation?
Subtitle Generation involves using software tools or artificial intelligence to automatically transcribe spoken words in a video and convert them into synchronized textual captions. These subtitles can be displayed at the bottom of the screen, helping viewers understand the content without needing audio. The process often includes speech recognition, language processing, and timing alignment to ensure the text matches the audio accurately. Subtitle generation is widely used in entertainment, educational content, marketing videos, and social media to reach diverse audiences.
