ChatGPT Voice in Chat gives Go and Plus users 3 hours, Pro ($100/month) users 15 hours and Pro ($200/month) users unlimited use per rolling 24-hour period, while Free users get limited access.
As of November 12, 2026, OpenAI’s ChatGPT Voice help page says voice mode now runs on Live. Free and Go use GPT-Live-1.1 Quip; Plus and Pro use GPT-Live-1.1. Unlimited Pro use is subject to abuse guardrails. Business Standard includes 3 hours and Business Premium 15 hours, with extra time at 1.25 credits per minute. Enterprise on usage-based pricing pays $0.05 per minute.
ChatGPT notifies you when you reach the limit, and a conversation can also end at the maximum session length or context limit. You can then continue in text. Advanced and Standard voice retire on December 11, 2026, when ChatGPT switches remaining users to Live. Voice in the desktop app has separate limits.
