OpenAI Adds Voice Conversations to Codex Threads

OpenAI has added voice conversation to Codex threads for its coding assistant, including support for existing threads and projects. Developers can now talk by voice with the same agent that wrote a piece of code or a PR — discussing implementation details, debating architectural trade-offs, and hashing out product decisions. You can jump into voice whenever back-and-forth is needed, and once things are settled the agent continues working autonomously. Multiple users relayed this official news on September 5.

Confirmed

• Voice can be invoked directly within existing Codex threads, letting you verbally discuss a PR or next steps with the same agent that wrote the code
• The official use case described: switch to voice when a problem requires back-and-forth discussion, then have the agent continue execution once the discussion is done
• User brandongalang relayed a finding from reachvb confirming that voice mode works in any Codex thread, including older, pre-existing sessions

Why it matters

• Previously, voice conversations were tied to new sessions, and the inability to continue old threads was a pain point for many users; brandongalang said this had long bothered him, and easier session resumption is a big help to daily work
• Voice suits discussions that need many rounds of back-and-forth, like architecture debates and design trade-offs, complementing autonomous agent execution and further reducing the switching cost of human-AI collaboration
