Abstract

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.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a touch screen sound detection method and device. Background technique [0002] Sound detection and recognition is a behavior recognition technology. The sound detection and recognition equipment continuously measures and records the waveform and changes of the sound emitted by the recognized object, and accurately matches the sound collected on the spot with the registered sound template to determine Sounds made by objects. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems exist in the above related technologies: [0004] In the prior art, traditional sound detection is generally based on laser Doppler effect and interference effect. Electronic devices based on these technologies acquire sound signals and output detection signals that are very weak and short-lived, resulting in relatively poor reliability of...
