xCORE VocalFusion™ SPEAKER


  • direct interface to microphone array with flexible backhaul
  • based on xCORE XVF3000 voice processor
  • voice DSP including beamformer, full duplex AEC and barge-in

 

Providing direct interfacing to four PDM (Pulse Density Modulation) microphones in either linear or circular arrays with a choice of USB or I2S interfaces to connect to application or host processors, VocalFusion Speaker provides the high performance far-field microphone solution for voice-activated speaker applications.

Based on the XVF3000 device voice sources are isolated from unwanted noise with the integration of advance DSP techniques including beamforming, echo cancellation and noise suppression. Optional keyword trigger detection delivered by Sensory TrulyHandsfree™ technology enables users to activate devices simply by speaking instead of having to physically touch the device.
