EveryWord ™ Software Stack

A highly-integrated vertical software stack developed in collaboration with Cirrus Logic gives customers the ability to integrate
far-field voice capture on the audio front end with Amazon Voice Services and other cloud services on the backend.

Hardware and software development validated in parallel with Amazon’s automated qualification testing along with additional requirements for larger spaces and non-line-of-sight capabilities.
