Amlogic A113X Smart Speaker

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.



Far-field Voice UI

  • Seamlessly add Alexa to your product to activate by voice from 6m+ range

Selectable mic array geometry

  • Select 2, 4 or 6-mic configuration to support cost-effective as well as high-performance design preferences

AVS 2.1 Premium far-field qualified

  • Out-of-the-box, optimized algorithms accelerate product development

Rapid prototyping on Audio Weaver

  • Easily develop and tune innovative product features using Embedded AWE Core and Audio Weaver Designer interface with drag & drop programming environment

Excellent music barge-in performance

  • Excellent trigger detection in the presence of device playback
  • TalkTo AEC significantly exceeds AVS premium specifications

Audio Front-end Features

DSP Concepts’ TalkTo for excellent far-field performance in noisy environments

  • • 6-mic adaptive beamformer with Single Channel Noise Reduction (SCNR)
  • • State-of-the-art noise cancellation with Adaptive Interference Canceller (AIC)
    • ○ No reference signal needed
    • ○ Eliminates 30dB of external noise sources such as background music or a booming movie
  • • 30+ dB Acoustic Echo Cancellation (AEC) for excellent barge-in performance

Support speaker output with integrated stereo playback processing
