Blind person barrier-free movie audio processing method and device and storage medium

The invention relates to a barrier-free film audio processing method and device for the blind and a storage medium, and the method comprises the steps: obtaining a feature film video frame queue QvideoES, a feature film audio frame queue Qaudio ES and an AD track audio frame queue Qaudio ES through separation, and completing the time axis synchronization; extracting a positive film processing segment PCM data frame sequence and an AD track processing segment PCM data frame sequence; performing voice activity detection on the PCM data frame sequence of the AD track processing section to obtain a voice activity state of each frame; calculating the volume of each frame of the positive film processing section PCM data frame sequence, and calculating a moving average value of elements of the positive film volume sequence one by one; modifying frames with inactive voice activity states in the PCM data frame sequence of the AD track processing section into mute values, and calculating moving average values of the re
