Alexa Voice Service (AVS) Integration is a new feature of AWS IoT Core that enables Alexa Voice to be produced on any type of connected device. AVS Integration for IoT Core reduces the cost of producing Alexa Built-in devices by up to 50% by offloading compute and memory intensive audio workloads to the cloud. With this reduction in production cost, customers can now cost-effectively build new categories of differentiated voice-enabled products such as light switches, thermostats, and small appliances. This allows consumers to talk directly to Alexa in new parts of their home, office, or hotel rooms for a truly ambient experience.
