ChatGPT can now read messages out loud. Simply touch and hold a message in the iOS or Android app and select the "Read Aloud" option. The web version has its own read-aloud button below the message. The synthetic voice in the demo doesn't sound quite as convincing as ElvenLabs and the like - probably for cost reasons. We had hoped that OpenAI would respond with GPT-4.5 or GPT-5 to Claude 3 just announced by Anthropic, which is supposed to surpass GPT-4. But reading messages out loud is fine, too.
