STMicroelectronics released an Amazon-qualified reference design package for smart connected devices leveraging Alexa Voice Service (AVS) Integration for AWS IoT Core.

The solution jump-starts the design of Alexa-enabled appliance controllers with the voice-user-interface software already integrated on MCUs within the STM32 family.

Per the company, the AVS Integration for AWS IoT Core reference design contains a compact 36mm x 65mm main board that combines a high-performance STM32H743 MCU and Wi-Fi module.

System features include:

  • Audio front-end processing
  • Communication interfaces and memory (RAM and Flash on a single chip
  • Audio-capture software
  • Advanced Audio Front End (AFE) with noise reduction, echo cancellation and advanced beam-forming signal processing for far-field audio detection
  • Amazon “Alexa” Wake Word
  • Connectivity to AWS IoT
  • Audio output software

The mentioned audio front end delivers far-field voice detection with closely spaced microphones. Further, the front end comes equipped with a free audio weaver tool license for fine tuning designs.

Users have the ability to customize designs by adding enhancements that include a second wake word, extra local commands, and a graphical display to combine with the voice command capabilities.
