Abstract: A system configured to perform user orientation estimation to determine a direction a user is facing using a deep neural network (DNN). As a directionality of human speech increases with frequency, the DNN may estimate the user orientation by comparing high-frequency components detected by each of the multiple devices. For example, a group of devices may individually generate feature data, which represents audio features and spatial information, and send the feature data to the other devices. Thus, each device in the group receives feature data generated by the other devices and processes this feature data using a DNN to determine an estimate of user orientation. In some examples, the DNN may also generate sound source localization (SSL) data and/or a confidence score associated with the user orientation estimate. A post-processing step may process the individual user orientation estimates generated by the individual devices and determine a final user orientation estimate.
