Application: Natural speech detection (Patent ID: US20240169982A1)
The patent filed by Cirrus Logic Inc. describes a system that includes multiple smart devices with microphones and processing circuitry to determine the orientation of a user's head based on speech signals received by the microphones. The orientation is determined by comparing power levels in different frequency bands and can be used to control the smart devices. The system can also estimate the user's focus of attention and associate user commands with specific devices based on the determined orientation.
The system's processing circuitry can compute power spectra, compare characteristics, and utilize neural networks to determine the user's head orientation. It can also communicate orientation information between devices, estimate user focus probabilities, and identify the device of focus. Additionally, the system can estimate the direction of the user's attention and control various smart devices based on the determined orientation. The patent covers a method for implementing this system in a network of distributed smart devices and a non-transitory storage medium with instructions for performing the method.
