OpenAI updating ChatGPT desktop app with GPT Voice for talking through work

OpenAI has integrated GPT-Live's full-duplex voice control into the ChatGPT desktop application for macOS and Windows. This update allows users to listen and speak simultaneously, eliminating rigid turn-taking while delegating complex reasoning to background models like GPT-5.5. The feature, which previously debuted on mobile, now directly powers agentic systems including Codex and ChatGPT Work. This integration enables developers to talk through work and complete tasks more naturally within their professional desktop workflows.
