Application Software Pack: Low Power Voice UI Enablement on i.MX MPUs
APPSWPACK-LPV-MPU Receive alerts
This pack deploys a Low Power Voice UI Enablement solution for i.MX 8M Mini and i.MX 8M Plus MPUs. It reduces power consumption with a Wake Word Engine designed to utilize the low power Cortex-M core. Upon wake word identification, the Cortex-M core wakes up the Cortex-A domain for better acoustic performance and advanced voice processing, reducing the power usage of traditional voice enablement solutions.
