8 best AI subtitle generators for 2023

In the past few years, video has dominated as consumers’ most preferred way of consuming content. Individuals and companies have taken notice–top YouTubers are making millions of dollars by releasing new weekly videos while 92% of marketers consider videos a key part of their corporate marketing strategy.

Because of this steady rise in video production and consumption, video editing platforms are also becoming increasingly popular. Many platforms are releasing advanced AI-powered features that ease video creation, such as AI subtitle generators. Many AI subtitle generators augment videos using state-of-the-art AI models that automatically add highly accurate subtitles to videos prior to publishing.

In this article, we will examine AI subtitle generators more closely, including what they are, how they work, and the eight best AI subtitle generators to use in 2023.

What are AI subtitle generators?

AI subtitle generators automatically transcribe audio and video speech at near-human level accuracy and add these subtitles directly onto the specified video. This process is especially useful for companies looking to more easily meet accessibility and compliance requirements. Adding subtitles to videos also makes them more searchable for SEO purposes.  

Typically, AI subtitle generators follow a multi-step process:

  1. User uploads a video file.
  2. AI subtitle generator applies an AI model to auto-generate subtitles.
  3. User edits the subtitles for accuracy, where necessary.
  4. User changes the way the subtitles are displayed (style, animation, color, font, etc.).
  5. User exports the video with hardcoded subtitles.

Most of the AI subtitle generators listed in this article can also detect and transcribe videos across myriad global languages for even greater reach and accessibility.

How do AI subtitle generators work?

Most AI subtitle generators utilize state-of-the-art AI models for speech recognition to convert speech to text via a simple API. These speech recognition models are trained on large amounts of audio data to automate a previously manual process without sacrificing accuracy.

For example, AssemblyAI’s Conformer speech recognition model was trained on 1.1 million hours of audio data and approaches human-level performance on real-world audio data.

The AI subtitle generator then takes this transcription data and outputs a transcription text that is displayed as the speaker speaks throughout the video. Under the hood, this generally works by converting the AI model’s output transcript into an SRT or VTT file. As noted above, users can also edit the subtitle text, change the font or size, add animations, or translate the transcription into multiple languages.
