Acer PurifiedVoice 2.0
Acer PurifiedVoice 2.0 uses AI to enhance microphone audio quality and reduce background noise on Acer Copilot+ devices with on-device NPU processing.
Why It Exists
Users need clear voice audio in noisy environments without manual audio setting adjustments or external noise-canceling accessories.
How It Works
Acer PurifiedVoice 2.0 is Acer's AI-powered audio enhancement system for Copilot+ PCs. Using the device's NPU, the system isolates voice from background noise, enhances speech clarity, and optimizes audio for calls and recordings. The system provides real-time noise suppression, echo cancellation, and voice level normalization. It also includes voice profile learning to personalize audio enhancement for each user.
Everyday Use Cases
- Noise suppression
- Voice isolation
- Echo cancellation
- Audio level normalization
- Voice profile learning
- Call quality enhancement
- Recording enhancement
User Workflow
- System captures audio from built-in or external microphones
- AI separates voice from background noise using NPU models
- Noise is suppressed and voice is enhanced in real-time
- System learns user voice profile over time
- Enhanced audio is output to callers or recordings
AI Processing Flow
Audio input is processed by on-device NPU neural models for real-time noise suppression. Multiple microphones are combined for spatial noise detection. Voice isolation uses spectral analysis to separate speech from background. Echo cancellation prevents feedback. Voice profile learning adapts to user characteristics. All processing is on-device without audio upload.
