Voice call data detection method, voice call data detection device, storage medium and mobile terminal

Abstract

The embodiment of the invention discloses a voice call data detection method, a voice call data detection device, a storage medium and a mobile terminal. The method comprises the steps of: after a voice call group in a pre-set application is established successfully, detecting that a squeal detection event is triggered, obtaining downlink voice call data in the pre-set time length, blocking, for each data block, obtaining a first frequency point having the maximum energy value in a high-frequency area and a second frequency point having the maximum energy value in a low-frequency area in the frequency domain, when the first frequency point satisfies a pre-set suspected squeal condition, determining that the first frequency point is a suspected squeal point in a current data block, and, when multiple suspected squeal point groups having periodic characteristic exist and the energy values corresponding to suspected squeal points are on the rise according to the sequence of data blocks which the suspected squeal points belong to, determining that squeal voice exists in the downlink voice call data. By adoption of the technical scheme in the invention, squeal detection on the downlinkvoice call data can be accurately carried out in time.

Description

technical field [0001] The embodiments of the present application relate to the field of voice call technology, and in particular, to a method, device, storage medium, and mobile terminal for detecting voice call data. Background technique [0002] At present, with the rapid popularization of mobile terminals, mobile terminals such as mobile phones and tablet computers have become one of the necessary communication tools for people. The communication methods between mobile terminal users are becoming more and more abundant, and they are no longer limited to the traditional telephone and short message services provided by mobile communication operators. In many scenarios, users are more inclined to use Internet-based communication methods, such as various Voice chat and video chat functions in social software. [0003] In addition, functions of applications (Applications, APPs) in mobile terminals are becoming more and more perfect, and voice call functions are set in many a...

Problems solved by technology

However, in the voice call process, the voice call data contains many types of sounds, such as the voices of each player, the sound of the application program itself (such as the background sound or special effect sound of the game, etc.), and the environment in which the mobile terminal is located. Other sounds, etc., due to the complexity of the sound, howling is prone to occur, seriously affecting the user's use
