13 MEMS microphones plus a Zynq SoC gives services like Amazon’s Alexa and Google Home far-field voice recognition clarity

Voice-controlled systems are suddenly a thing thanks to Amazon’s Alexa and Google Home. But how do you get reliable, far-field voice recognition and robust voice recognition in the presence of noise? That’s the question being answered by Aaware with its $199 Far-Field Development Platform. This system couples as many as 13 MEMS microphones (you can use fewer in a 1D linear or 2D array) with a Xilinx Zynq Z-7010 SoC to pre-filter incoming voice, delivering a clean voice data stream to local or cloud-based voice recognition hardware. The system has a built-in wake word (like “Alexa” or “OK, Google”) that triggers the unit’s filtering algorithms.

Aaware’s technology makes significant use of the Zynq Z-7010 SoC’s programmable-logic and DSP processing capabilities to implement and accelerate the company’s sound-capture technologies including:

 

 

  • Noise and echo cancellation
  • Source detection and localization
