The Arm Total Solution keyword detection application (ATS-Keyword) detects keywords in the audio input using Machine-Learning model DS-CNN and publishes recognized keywords to AWS IoT Service in the cloud.

The audio data to process are injected at run time from using the virtual audio streaming interface. Additionally the AWS IoT service is used for OTA firmware updates. These firmware updates are securely applied using Trusted Firmware-M.

For more information, refer to the example descriptions in the [ATS-Keyword GitHub repository] (https://github.com/ARM-software/open-iot-sdk/tree/main/examples/ats-keyword).
