Infineon fuses Radar and MEMS microphone data through XMOS’ audio processor

Technology News |

By combining audio capture with radar target presence detection (using Infineon’s MEMS 70dB SNR microphone and 60GHz 2Tx/4Rx radar IC) with XMOS’ audio processor for appropriate beam forming, the two companies have been able to demonstrate far field voice capture for optimal sound recognition and flawless execution for digital voice assistance across a broad range of voice-controlled devices.

The XMOS audio processor analyses the signal data from an array of Infineon’s digital microphones, adjusting the angular and distance data from each microphone to produce a beam at an angle identified by the radar data. A lit LED indicates presence detection and where sound is taken from.

The combination of an Infineon radar and the XMOS beamformer allows the microphone to target a specific object precisely, even with the object moving and indistinctive noise. The new microphone set up is said to deliver a superior user experience compared to existing voice-controlled systems, with clear understanding of commands and flawless execution that prevents unwanted activations of devices.

Target applications include the smart home as well as smart TVs and set top boxes, secure keyless entry systems, and other voice-operated consumer devices.
