At Mobile World Congress, XMOS launched its VocalFusion Stereo Development Kit powered by Infineon for Amazon Alexa Voice Service (AVS).
The new kit from XMOS presents the first linear mic array solution qualified by Amazon for far-field performance that supports stereo acoustic echo cancellation.
In October 2017, XMOS launched its mono VocalFusion 4-Mic Dev Kit, also qualified by Amazon for AVS. Both kits integrate Infineon’s high signal to noise ratio (SNR) XENSIV MEMS microphone IM69D130 to ensure the highest performance and reliability.
With this announcement, XMOS now has more far-field qualified Amazon AVS Dev Kits than any other vendor.
“Our strategic partnership with Infineon and the use of their high-performance microphones helps us to deliver outstanding far-field performance,” said Mark Lippett, President and CEO of XMOS. “The combination of the XENSIV MEMS microphones and the XVF3500 voice processor delivers a class-leading user experience.”
Infineon’s high-performance digital XENSIV MEMS microphone IM69D130 provides premium audio raw data, perfect to combine with XMOS’s advanced audio signal processing algorithms to handle even most demanding scenarios.
Using XENSIV MEMS microphones, far-field and whispered voice pick-up performance can be achieved with a signal to noise ratio of 69 dB, and exceptionally low distortion of less than 1% up to 128 dB sound pressure level.
The new VocalFusion stereo development kit features a VocalFusion XVF3500 voice processor which supports full duplex stereo-AEC (Acoustic Echo Cancellation). It is designed for developers working on Alexa-enabled stereo electronics, including smart TVs, soundbars, set-top boxes, digital media adapters, audio and visual equipment.
