AVS on MIMXRT1020-EVK

[BharathGowda]

I am using MIMXRT1020-EVK for a hackathon(https://www.electromaker.io/contest/nxp-hackathon-2021) to build voice-controlled automation. Please point me to AVS SDK for MIMXRT1020-EVK. In SDK builder if I select AVS it's only showing the MIMXRT1060 board. If MIMXRT1020-EVK is not compatible with AVS, at least provide me documentation to use MIMXRT1020-EVK's audio input and output to build basic voice commands control.

Hello BharathGowda,

The The NXP EdgeReadt MCU-based solution for Amazon’s Alexa Voice Service (AVS) is based on the i.MXRT1060 (link below for more information on this solution) so there is not AVS support for the i.MXRT1020.

The i.MXRT106x processors are licensed to run AVS or NXPs cloud-based voice assistant software solutions as listed on the following document.

My apologies for the inconvenience.

Regards,
Gustavo

Please point me out to audio sdk for MIMXRT1020-EVK (recording from the mic and playing through speaker). So I can build my own basic recognition engine.

Hello BharathGowda,

There is not an audio SDK per se but among the SDK examples there are some that may be helpful, like the SAI examples for record and playback.
