Voice Mode Reaches Existing Codex Threads

Guinness Chen, an OpenAI engineer on the Codex and ChatGPT Voice teams, stated that voice can now be started from any existing Codex thread. Users can discuss a PR, debate architecture, or plan next steps with the agent before returning to text. The change is live on ChatGPT Desktop and iOS, with Android support arriving next week. Multiple OpenAI engineers shared the update and noted it removes an earlier limitation when moving between voice and thread views.
