It may have been a chaotic week at OpenAI, but the company has somehow still found time to roll out a product. "ChatGPT with voice" is available to free users of the ChatGPT app. This feature launched for paying users in September, and if you haven't heard, it's a full-blown voice assistant. The feature is still slowly rolling out to devices; on my Android phone, I don't have a "headphone" icon anywhere, even with a Plus subscription.

When you have the feature, you can open the app, press the "headphone" icon, ask a question, and a stilted robot voice will read out a reply. It's just like the voice assistants from Apple, Amazon, or Google, but this one is powered by a large language model. ChatGPT's voice model is purely a question-and-answer type of voice assistant, though. Usually, these things are handy for what they can do on your behalf—make a phone call, control a smart home, take a note, or make a calendar appointment—but this can only answer questions.
