The traditional speaker market has evolved in recent years to go far beyond audio amplification. Speakers have gone wireless, allowing much more freedom in their installation and placement in the home, and more recently speakers have become smart. Smart speakers typically integrate the ability to process voice commands via connectivity to the Cloud and are able to play the role of a virtual assistant. Smart speakers can also be integrated into a home automation devices system allowing voice control of the home environment.

ST provides range of products to support smart speaker designs. Key products include audio amplifiers, Bluetooth and NFC connectivity solutions, analog and multi-mode digital MEMS microphones with high dynamic range, and proximity sensors for gesture control. We also offer power management and battery management devices to optimize battery life as well as a range of flexible USB Type-C and Power Delivery solutions.
