OpenAI began notifying ChatGPT users on November 10 that Advanced Voice Mode and Standard Voice Mode will be discontinued on December 11, 2026, consolidating all conversational voice in ChatGPT on GPT-Live, the full-duplex model launched in July that can listen and speak at the same time. Anyone still on a legacy mode will be switched to GPT-Live automatically, and both options will disappear from Settings — Voice.

OpenAI's case is usage: it says voice use has nearly doubled since GPT-Live launched and that most voice users are already on it. Previous voice conversations stay in history and can be continued by text or GPT-Live. The retirement is not total under the hood — live video and screen sharing will keep running on Advanced Voice because GPT-Live does not support them yet, with no timeline given, and voice chats with custom GPTs stay on Advanced Voice until the December 11 cutoff.

Some users are pushing back, arguing GPT-Live's interrupt-heavy style and shorter answers are worse for complex spoken reasoning than the older modes. OpenAI says feedback from people who preferred the legacy modes will shape GPT-Live work on more detailed responses, continuity and personalization. This is the second attempt at retiring Standard Voice: user backlash forced a U-turn in September 2025, but this time the cutoff is printed in the release notes.
