Amlogic A113X Smart Speaker

The Amlogic A113X design is flexible and configurable to 2,4 or 6 mic arrays to integrate high performance smart audio far-field voice activation. This flexible development solution uses DSP Concepts' AVS 2.1 Far-field qualified TalkTo, delivering accurate wake word detection at a lower cost and a fraction of the CPU resources on an ARM cortex-A53 core.
