An augmented reality interaction system applied to a physical scene and comprising a server and a plurality of mobile devices is provided. The server stores a point cloud map corresponding to the physical scene, and one of the mobile devices uploads a physical image, role state variation data and local variation data to the server. The server compares the physical image with the point cloud map to generate orientation data of the mobile device in real time, and adjusts role data corresponding to a user according to the role state variation data and the local variation data. The server pushes the orientation data of the mobile device and the role data to the other mobile devices such that augmented reality images displayed by the other mobile devices are adjusted in real time according to the orientation data of the mobile device and the role data.

A speech enhancement method is disclosed. The method includes the steps of: receiving a plurality of frames of sound signals by a microphone array; calculating an inter-aural time difference for each frequency band of each frame of the sound signals corresponding to at least one two-microphone set of the microphone array; calculating a plurality of values of cumulative histograms according to the calculated inter-aural time differences, wherein each value of the cumulative histograms is associates with a sound signal intensity of a respective frame; determining a first inter-aural time difference threshold according to the calculated value of the cumulative histograms; and filtering the plurality of frames of sound signals according to the first inter-aural time difference threshold.
