The XMOS Audio Processor analyzes the signal data from the Infineon digital microphone array. It has ability to adjusts the angle and distance data for each microphone. And forms the beam at the angle determined by the radar data.
Infineon Technologies, Inc., together with XMOS, has introduced a new voice recognition component. The component combines Infineon’s radar and a silicon microphone sensors with XMOS’s audio processors to perform far-field speech recognition through audio beam forming and radar target location detection.
These devices are integrated together to achieve optimal speech recognition. And can achieve the perfect implementation of voice control equipment. Target applications includes smart home, smart TV and set-top boxes, secure keyless entry systems and other voice-activated consumer electronics devices.
XMOS Audio Processor For Optimal Speech Recognition Radar Technology
The performance of the current MEMS microphone will limit the effectiveness of the system. Also in a multi-person voice sorrundings, it detects the sound source with the authenticity of location that can not be accurately identify. Also it can not separate from the inanimate body noise. Infineon’s XMOS Audio Processor 60 GHz 2Tx / 4Rx radar IC has an antenna with 70dB SNR which helps microphone to overcome these problems.
XMOS Audio Processor microphone is based on Infineon’s dual-back-pole MEMS technology. And is ideal for far-field voice capture and beam forming. In addition, the optimization of the microphone is the signal-to-noise ratio will further improve performance of the device.
More Better Voice Recognition XMOS Audio Processor
So here the XMOS Audio Processor analyzes the signal data from the Infineon digital microphone array. Also it adjusts the angle and distance data for each microphone. And forms the beam at the angle determined by the radar data. The LED lights indicate presence detection and sound source location.
The combination of Infineon radar and XMOS beam formers XMOS Audio Processor helps to create the microphone accurate specific target , even if the target is moving or has a faint noise. So as compared with the existing voice control system, the microphone can provide excellent user experience. And XMOS Audio Processor clearly understand the instructions and achieve the perfect implementation to prevent the device accidentally start.
