TikTok Gets Sued by Actor Behind Text-to-Speech Feature On 5/11/21 at 3:50 AM EDT A voice actor is suing TikTok for using her voice in the app's text-to-speech tool without her permission. The feature is often used to narrate the video without TikTok users having to use their own voices. It's also used humorously, as the auto-generated narration pronounces misspelled words or names incorrectly. The text-to-speech option can be used by adding text to the video and holding down the words. A text-to-speech option will appear and once selected, it will then automatically read out loud the words the user has written.
