Infineon's high SNR microphone power the Amazon AVS far-field development Kit

     XMOS launches VocalFusion4 microphone development kit for far-field applications for Amazon Alexa voice services. The package integrates Infineon's high signal-to-noise ratio microphone to ensure maximum performance and reliability. XMOS has now launched the first Amazon AVS development kit that supports linear microphone arrays for far-field applications.

     The VocalFusion4 microphone development kit captures clear speech even in noisy environments. This allows commands to be precisely captured across the room and processed by Alexa's cloud-based voice recognition system, said MarkLippett, president and CEO of XMOS: "The combination of Infineon's high-performance microphone with XMOS's VocalFusion processor, It allows us to develop powerful far-field voice capture solutions that have been difficult to achieve until now.

     Infineon's microphones have extremely low noise of their own (signal-to-noise ratio of 69dB), excellent microphone-to-microphone phase and sensitivity matching, and support low latency and fast signal conversion, ensuring excellent hit rates for far-field applications and extended voice pickup distances. Dr. RolandHelm, Head of Infineon's Sensors business unit, said: "The combination of XMOS processing power, algorithmic knowledge and Infineon's microphone hardware makes it ideal for far-field voice user interface solutions for applications that use multiple microphones. In this way, we can meet the expectations of ambitious end users.

     Last month, Infineon Technologies AG announced a strategic investment in XMOS with the goal of taking enhanced human-computer interaction solutions to new heights. Addressing the challenges of the voice interface market is the first step in a collaboration that focuses on making communication between people and smart devices as seamless as possible in the future
