AI Audio Capture
Far-field capture and voice front end for device integration: array, noise control, wake word, and audio output.
System Capabilities
- Microphone array
Array geometry follows the device cavity.
- Beamforming and AEC
Front-end processing for speaker echo and steady noise.
- VAD and far-field wake
Wake word and endpointing held on the target direction.
- Audio interface
I2S / USB, audio stream, and recognition callbacks.
Solution Structure
Architecture
Microphone array, beamforming, echo cancellation, voice activity detection, and far-field wake, then an audio stream or recognition result.
Metrics
Metrics will be added after measurement. Unverified numbers are omitted.
Interfaces
I2S / USB, audio stream, and recognition callbacks.
Deployment
Voice front-end module for conference gear, appliances, terminals, and industrial devices.
Deliverables
Array layout, front-end firmware, interface notes, and cavity tuning.
Engagement
Tuning follows cavity, speaker placement, and the noise scene.
Deliverables
Voice front-end layout
Integrable design, firmware, and interface notes for this solution.
Array geometry, cavity tuning, I2S / USB audio, and recognition callbacks.
Technical Specifications
Microphone array
Multi-mic
Mic count and spacing follow the cavity and target distance.
Front end
Beamforming / AEC / VAD
Handles speaker echo and steady noise, plus wake word and endpointing.
Interfaces
I2S / USB
Audio stream out, recognition results by callback.
Metrics
Pending measurement
Wake distance, SNR, and false wakes are filled in after scene tests.
Technical engagement by scene
Share the site, interfaces, and cycle time. We confirm architecture and delivery scope from that.
