Celia Whisper (2024)
Hands-free voice assistant interaction via raise-to-speak gesture, shipped on Huawei flagship devices.
Celia Whisper
Celia Whisper is a hands-free voice assistant interaction mode that I led the development of at Huawei. It enables users to issue voice commands to Huawei's AI assistant without speaking the traditional wake word, by simply raising the phone close to the mouth.

How It Works
The system combines on-body sensing with proximity detection: when the user lifts the phone with the microphone positioned within 5cm of the mouth, voice processing is automatically activated. This eliminates the need for verbal wake phrases, enabling natural and discreet voice interaction.
Key Features
- Wake-word-free activation: Raise-to-speak gesture replaces the traditional "Hey Celia" wake word.
- Quiet environment usage: Designed for scenarios requiring silence, such as libraries, meetings, and theaters.
- Adaptive volume response: The assistant's reply volume automatically adjusts based on detected user voice levels.
