UHD AI Voice-based AI assistant device for UHD broadcasting by use of array speakers and array microphones

摘要

The present invention generally relates to an AI voice assistant device suitable for an environment in a stereoscopic audio environment of UHD broadcasting. In particular, according to the present invention, as a stereophonic audio environment having 10 or more audio channels as well as a 4K or higher high-definition video environment is established in the UHD broadcasting standard, an array speaker and an array microphone are mounted on an AI voice assistant device handling UHD contents, When not in the correct position, the delay deviation is reflected in the sonic sound processing in response to the phase shift and the weight is applied to the speech recognition processing to support the stereoscopic sound according to UHD broadcasting to the in-house viewers, while also smoothly performing command recognition by the viewer's voice. It's about the technology that allows you to do it. According to the present invention, there is an advantage in that the AI voice assistant function can be smoothly utilized while enjoying the stereophonic audio of UHD broadcasting. In addition, according to the present invention, even when a phase change occurs in the position of a viewer, the delay deviation according to the phase shift is reflected in the stereoscopic sound processing of the array speaker, thereby maintaining a comfortable stereoscopic audio environment. In addition, according to the present invention, even when a phase shift occurs in a viewer's position, there is an advantage of smoothly performing command recognition by applying a weight according to a phase shift to speech recognition processing through an array microphone.
