In the rapidly evolving landscape of smart retail and QSR (Quick Service Restaurants), Voice AI Kiosks are becoming the standard for contactless interaction. However, the real-world challenge lies in the environment: bustling malls, heavy traffic in drive-thrus, and ambient wind noise.
As a premier provider of audio pickup solutions, Wuxi Silicon Source Technology (SISTC) understands that the success of any Voice AI platform starts at the hardware level.

The Foundation: High Signal-to-Noise Ratio (SNR)
In environments where background noise exceeds 60dB, a standard microphone often fails. To ensure the AI engine receives a “clean” signal, the MEMS microphone must have a high SNR. Our latest MEMS components provide the clarity needed for deep-learning noise reduction algorithms to distinguish between a customer’s order and the surrounding chaos.
Advanced Microphone Array & Beamforming
Single-microphone setups are rarely sufficient for far-field voice recognition. We specialize in supporting our partners with Microphone Array design. By precisely placing multiple MEMS units on a custom-designed PCB, the system can utilize Beamforming technology to “focus” on the user while suppressing lateral noise.
Technical Note: For our OEM partners, we provide detailed 3D CAD files and engineering drawings to ensure the acoustic porting aligns perfectly with the kiosk’s mechanical housing, preventing internal resonance.
High Acoustic Overload Point (AOP) for Outdoor Durability
Outdoor kiosks often face sudden loud noises, such as sirens or engine revving. A microphone with a low AOP will “clip” the signal, causing the AI to lose the connection. Our high-AOP MEMS solutions ensure that even under extreme sound pressure, the audio remains linear and undistorted.
Seamless Integration: Radar and Low-Power Wake-up
To maximize energy efficiency, many modern AI terminals utilize Radar sensors for presence detection. By integrating our high-precision Radar modules with low-power MEMS microphones, the Kiosk can remain in a “sleep” state until a user approaches, instantly triggering the Voice AI for a seamless experience.
