The xCORE-VOICE Smart Microphone (XK-USB-VSM-2000) is end of life and will be withdrawn from sale effective 2017-11-02. For further information including recommended replacement see EOL notice.
The xCORE-VOICE Smart Microphone, featuring the XVSM-2000 silicon device, combines high performance MEMS microphone aggregation output with advanced DSP technology and xCORE's industry leading control and communications flexibility.
The XVSM-2000 can be used stand-alone as a USB conferencing solution, or embedded with an Applications Processor to provide a high-integrity voice interface for applications such as voice controlled IoT devices.
Offering advanced DSP capabilities including beamforming, acoustic echo cancellation and de-reverb ensure that voice sources can be delivered with the highest possible quality, guaranteeing the best user-experience. Audio output processing enables full-duplex communication, either with conference participants, or speech recognition systems.
