ChatGPT and Claude both get upgraded voice features; Codex also enables giving agents instructions by voice only

OpenAI and Anthropic both upgraded their voice AI features on the same day.

ChatGPT Voice is now available on desktop for macOS and Windows, letting users control agents and Codex by voice.

Anthropic refreshed Claude’s voice mode with spoken conversations on higher-end models, external tool integration, and broader language support.

The updates push voice AI beyond chat into hands-free agent control and productivity workflows.
