There’s no need to search audio libraries or pay royalty fees — just use Captions to make your own unique songs.
Make your AI twin
Sonic’s text-to-speech generator has a wide range of AI actors to choose from, but what if you’d rather be the face of your own content? No problem — advanced AI technology can now copy your voice and likeness and use them to generate videos. The process is simple: Just record a video of yourself reading a prepared script, and Captions’ AI Twin feature will build an AI avatar that you can use for future video creation. To make new content, all you’ll need to do is prompt Captions with a new script. AI will then create a highly realistic video of you reading it. You’ll never have to sit in front of a camera again.
Emphasize your message
Sonic’s text-to-speech tool gives your posts a clean, professional voice. To polish this audio further, generate custom sound effects to pair with your message.
