Product overview

Description

The STEVAL-VOICE-UI Amazon™ qualified evaluation kit is designed to allow evaluation of a cost-effective way to integrate AVS for AWS IoT Services® into smart devices, so they can implement state-of-art, hands-free voice control based on natural language comprehension.

Users will therefore enjoy a heightened experience with target IoT end products, with the ability to talk to Amazon Alexa and control smart home devices, get assistance, listen to the news, check the weather forecast, play music, etc.

The software package implements audio front-end, Amazon wake word, audio playback and Amazon Alexa® communication protocol software. The SDK runs on internal memories only, offering maximum integration and cost-effective solutions.

The STEVAL-VOICE-UI is built with a modular approach for easy prototyping and debugging purposes as well as easy adaptation to specific microphone spacings, user interface and audio output requirements.
