Title:
SMART SOUND FIELD CALIBRATION SYSTEM, SMART SOUND FIELD ADAPTATION SYSTEM, AND SMART SPEECH PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/166029
Kind Code:
A1
Abstract:
The present application relates to a smart sound field calibration system, at least comprising an auto-detection portion, an audio information collection portion, a data processing portion and at least one speaker, the audio information collection portion at least being provided with an audio acquisition device and a microphone. A data trigger unit in the data processing portion triggers at least one sound field adaptation model stored in a storage unit, to rapidly adjust a speaker angle within a sound field, so that a whole speaker playback system can perform smart adjustments in real time on the basis of stored sound field adaptation models when a speaker number parameter, a speaker position parameter or an audience position parameter changes, in order to provide users with a better listening experience. In addition, real-time sound field adaptation and sound field adjustment and calibration are performed on different microphone types in a fixed sound field environment by means of different sound data sources acquired by the audio acquisition device and the microphone in the audio information collection portion, so that the speaker system is more compatible.
