Touch screen sound detection method and device

The invention discloses a touch screen sound detection method and device. The method comprises the following steps of acquiring an audio signal recorded by a user through touch screen equipment, performing correlation analysis on the audio signal and a template signal to obtain a correlation coefficient between the audio signal and the template signal, and determining whether the audio signal contains the touch screen sound or not according to the correlation coefficient. Correlation analysis is carried out on the template signal and the audio signal recorded by the touch screen device, so that whether the audio signal contains the touch screen signal is determined, and the accuracy of touch screen signal detection is improved. 本发明公开一种触屏声音检测方法和装置，该方法包括以下步骤：获取用户通过触屏设备录制的音频信号；对所述音频信号与模板信号进行相关度分析，得到所述音频信号与所述模板信号之间的相关系数；根据所述相关系数确定所述音频信号是否包含触屏声音。本发明对模板信号以及通过触屏设备录制的音频信号进行相关度分析，从而确定音频信号是否包含触屏信号，提升了触屏信号检测的准确率。
