In one of the biggest updates to ChatGPT yet, OpenAI has launched two new ways to interact with its viral app.  

First, ChatGPT now has a voice. Choose from one of five lifelike synthetic voices and you can have a conversation with the chatbot as if you were making a call, getting responses to your spoken questions in real time.

ChatGPT also now answers questions about images. OpenAI teased this feature in March with its reveal of GPT-4 (the model that powers ChatGPT), but it has not been available to the wider public before. This means that you can now upload images to the app and quiz it about what they show.

These updates join the announcement last week that DALL-E 3, the latest version of OpenAI's image-making model, will be hooked up to ChatGPT so that you can get the chatbot to generate pictures.

The ability to talk to ChatGPT draws on two separate models. Whisper, OpenAI’s existing speech-to-text model, converts what you say into text, which is then fed to the chatbot. And a new text-to-speech model converts ChatGPT’s responses into spoken words.
