INTERFACE

High-performance, easy-to-integrate lightweight voice interface that provides clear voice for communication and tuned signal for ASR simultaneously.
Far-Field 5 m Capture
ASR & Comms Channels
Plug-and-Play

Get Optimized Voice Instantly

The compact dual-microphone array features audio front-end processing that enables clear voice capture from up to 5 meters away. The powerful MCU simultaneously processes and optimizes both voice recognition and conference calls, providing dedicated dual-channel output for these tasks.

Integrated DSP Suite

Built-in AEC, Interference Canceller, Noise Suppressor and AGC enable clear 5-meter far-field voice pickup while eliminating echoes and background noise without host CPU load, cutting tuning effort by up to 80%. Barge-in ability allows more efficient and continuous dialogue flow.
