Microsoft has announced a significant reveal for Windows scheduled for Thursday, focusing on advancements in voice technology. The enhancements include upgrades to Voice Access and the introduction of a "Hey Copilot" wake word for voice activation, both currently in public preview. The announcement hints at a major update, although specific features are not disclosed. The Windows for Business roadmap indicates that "natural language commanding" will enhance Voice Access, suggesting more sophisticated spoken controls. Recent Insider builds have introduced a "wait time before acting" feature in Voice Access.
