I wrote a bit about DSP selection here.

TL;DR version:

  • Lots of choice available now
  • Need to understand if your device will be used for push-to-talk, near field, or far field
  • For Alexa Voice Service, far field may require four mics
  • Another key benefit — you can have a low power wake word
  • Not a good idea to try to implement your own far field DSP

Enjoy!
