Howling detection method and device and electronic equipment

The invention discloses a howling detection method and device and electronic equipment, and the method comprises the steps: determining the signal type of a to-be-detected signal according to the sum of the energy of a first frequency band of the to-be-detected signal; wherein the frequency point of the first frequency band is smaller than a first frequency point threshold, the signal type is used for indicating that the signal to be detected is a voice frame signal or a non-voice frame signal; obtaining frequency domain feature information of the to-be-detected signal; and when each parameter in the frequency domain feature information is within a preset parameter range corresponding to the signal type, determining that howling exists in the to-be-detected signal. The howling in the to-be-detected signal can be accurately detected. 本申请公开了一种啸叫检测方法、装置及电子设备，该方法包括：根据待检测信号的第一频带的能量和，确定待检测信号的信号类型；该第一频带的频点小于第一频点阈值；该信号类型用于指示待检测信号为语音帧信号或者非语音帧信号；获取待检测信号的频域特征信息；当频域特征信息中各参数位于信号类型对应的预设参数范围内时，确定待检测信号中存在啸叫。可以准确检测出待检测信号中的啸叫。
