音频文件仍在python中重复自身

当我运行以下代码时，即使在将条件设置为0（键盘\选择\帧）后，音频文件也会重复自身多次

以下是while循环的正确性，如下所示：

        if select_keyboard_menu is True:
        # Detecting gaze to select Left or Right keybaord
        gaze_ratio_left_eye = get_gaze_ratio([36, 37, 38, 39, 40, 41], landmarks)
        gaze_ratio_right_eye = get_gaze_ratio([42, 43, 44, 45, 46, 47], landmarks)
        gaze_ratio = (gaze_ratio_right_eye + gaze_ratio_left_eye) / 2

        if gaze_ratio <= 0.9:
            keyboard_selected = "right"
            keyboard_selection_frames += 1
            # If Kept gaze on one side more than 15 frames, move to keyboard
            if keyboard_selection_frames == 15:
                select_keyboard_menu = False
                right_sound.play()
                # Set frames count to 0 when keyboard selected
                frames = 0
                keyboard_selection_frames = 0
            if keyboard_selected != last_keyboard_selected:
                last_keyboard_selected = keyboard_selected
                keyboard_selection_frames = 0
        else:
            keyboard_selected = "left"
            keyboard_selection_frames += 1
            # If Kept gaze on one side more than 15 frames, move to keyboard
            if keyboard_selection_frames == 15:
                select_keyboard_menu = False
                left_sound.play()
                # Set frames count to 0 when keyboard selected
                frames = 0
            if keyboard_selected != last_keyboard_selected:
                last_keyboard_selected = keyboard_selected
                keyboard_selection_frames = 0

如果选择键盘菜单为真：
#检测凝视以选择左键或右键
凝视比率\左眼=获得凝视比率（[36,37,38,39,40,41]，地标）
凝视比率\右眼=获得凝视比率（[42,43,44,45,46,47]，地标）
凝视比率=（凝视比率\右眼+凝视比率\左眼）/2
如果有，则为u比
