Infineon: high SNR MEMS microphones complement Amazon AVS far-field development kit

XMOS has launched its VocalFusion 4-Mic Dev Kit for Amazon Alexa Voice Service (AVS) for far-field applications. The kit integrates Infineon’s high SNR microphones to ensure highest performance and reliability. XMOS now offers the first Amazon AVS development kit with a linear mic array for far-field applications. The 4-Mic Development Kit features crystal clear voice capturing even in noisy environments. This enables commands to be accurately captured from across the room for processing by the Alexa cloud-based speech recognition system.

Infineon’s microphones provide very low self-noise (69 dB SNR), distinguished microphone to microphone phase and sensitivity matching as well as fast signal conversion for low latency, ensuring  excellent hit rate and extended voice pick-up distance for far-field applications.

Last month, Infineon Technologies announced a strategic investment in XMOS, with the target to bring solutions for enhanced human machine interaction to the next level. Addressing the voice interface market is the first step of the partnership which will focus on making the communication between humans and smart devices as seamless as possible in future.
