Voice & audio
OpenAI
Turn any written words into natural-sounding speech with voices that actually sound human
Using OpenAI TTS is like hiring a professional voice actor who's available instantly, never gets tired, and can read anything you write in seconds for pennies per page
OpenAI TTS is a text-to-speech service that reads any text out loud in a natural, human-sounding voice. You give it words, and it gives you back an audio file with one of several different voices speaking those words clearly. People use it to add voiceovers to videos, create audio versions of articles, build phone systems that talk to customers, or make apps that can speak to users. It's the same technology behind ChatGPT's voice feature.
