OpenAI and Anthropic Push Voice as a Control Layer for AI Agents

On July 23, 2026, OpenAI added ChatGPT Voice to its desktop app, pairing spoken multi-step commands with Codex and computer-use tooling. Anthropic updated Claude's voice mode around the same date for tasks across Gmail, Slack, Notion, and Canva. Both frame voice as a command surface for agentic workflows — AI systems that take multi-step actions — rather than a conversational interface.
