Voice Control Gateway


Controlling all your home devices using Amazon Voice services (aka Alexa), Google assistant or a third-party/proprietary cloud-based IA is today’s trend. Sometimes it requires a mix of these IAs. To avoid constantly sending sound, keyword/hot word detection must be done locally.

These devices connect to the voice-controlled intelligent personal assistant service such as Alexa or Google to control the devices paired to it.

This voice control gateway can control multiple smart devices in your house with cloud-to-cloud communications and access to multiple services such as, streaming music, accessing an agenda, turning lights on and off, making phone calls and searching the internet.
NXP has developed a range of solutions for adding voice control directly into any product. From flexible implementations to completely turnkey solutions, NXP offers scalable options from high-performance MPUs to cost-effective MCUs.


  • Multi-channel audio and digital microphone inputs
  • Connectivity (I2C, SAI, UART, SPI, SDIO, USB, PCIe, Gigabit Ethernet)
  • Consumer and Industrial
  • Programmable LED brightness
  • Android™, Linux®, FreeRTOS and partner commercial operating systems.
