Product Introduction

1. Microsoft’s "Hey, Copilot!" is a voice-activated feature for Windows Insiders that enables hands-free interaction with Copilot Voice using the wake phrase "Hey, Copilot."
2. The core value lies in streamlining productivity by allowing users to access AI-powered assistance without manual input, maintaining workflow continuity while seeking information or brainstorming ideas.

Main Features

1. The feature uses on-device wake word detection to trigger Copilot Voice, ensuring immediate responsiveness without requiring physical interaction with the device.
2. A floating UI appears at the bottom of the screen with a microphone icon and audio chime to confirm activation, followed by cloud-based processing for voice queries after the wake word is detected.
3. Conversations end automatically after inactivity or via manual closure, with a hang-up chime or voice confirmation to signal termination, minimizing disruptions to ongoing tasks.

Problems Solved

1. It eliminates the need to manually open or interact with the Copilot app, addressing interruptions during focused work or creative sessions.
2. The feature targets Windows Insiders and productivity-focused users who prioritize seamless multitasking, such as professionals, students, or creatives.
3. Typical scenarios include requesting real-time information (e.g., weather updates), troubleshooting technical issues, or refining ideas without switching applications.

Unique Advantages

1. Unlike cloud-dependent voice assistants, "Hey, Copilot" processes wake-word detection locally, reducing latency and enhancing privacy by avoiding continuous audio streaming.
2. The on-device 10-second audio buffer ensures no voice data is stored or transmitted until the wake word is detected, aligning with strict privacy standards.
3. Integration with Windows Insider builds allows rapid iteration based on user feedback, ensuring feature refinement ahead of general availability.

Frequently Asked Questions (FAQ)

1. How do I enable "Hey, Copilot"? Enable it via Copilot’s settings by navigating to the avatar icon > Settings > Voice mode > Toggle "Listen for ‘Hey, Copilot’," which is disabled by default.
2. Why does Windows show the microphone in use when "Hey, Copilot" is enabled? The system tray indicates microphone activity because the wake-word detector runs continuously in the background, though no audio is stored or transmitted until activation.
3. Does "Hey, Copilot" work offline? Wake-word detection functions offline, but responses require internet connectivity for cloud processing, similar to typed Copilot interactions.
