Tensorflow 我应该添加什么，以便当系统检测到某些特定对象时，它将播放警报声音？

我用网络摄像头做了物体检测api，系统运行成功检测到物体，现在我想补充一下，当系统检测到某个特定物体时，它会播放diff alert声音

while True:
    # Acquire frame and expand frame dimensions to have shape: [1, None, None, 3]
    # i.e. a single-column array, where each item in the column has the pixel RGB value
    ret, frame = video.read()
    frame_expanded = np.expand_dims(frame, axis=0)

    # Perform the actual detection by running the model with the image as input
    (boxes, scores, classes, num) = sess.run(
        [detection_boxes, detection_scores, detection_classes, num_detections],
        feed_dict={image_tensor: frame_expanded})

    # Draw the results of the detection (aka 'visulaize the results')
    vis_util.visualize_boxes_and_labels_on_image_array(
        frame,
        np.squeeze(boxes),
        np.squeeze(classes).astype(np.int32),
        np.squeeze(scores),
        category_index,
        use_normalized_coordinates=True,
        line_thickness=8,
        min_score_thresh=0.60)
    #if xxxxx:
    #    alert.play()
    #else:
    #    pass
    # All the results have been drawn on the frame, so it's time to display it.
    cv2.imshow('Object detector', frame)

    # Press 'q' to quit
    if cv2.waitKey(1) == ord('q'):
        break

我的系统是自动检测危险武器的，当我的系统检测到“枪”或“刀”时，它将使用声音警报提醒安全。

适用于Windows

import winsound

winsound.PlaySound("sound_file.wav", FLAG)

或者只是一声嘟嘟

import winsound

dur = 500 # as millisecond
freq = 2000 # sound frequency
winsound.Beep(freq, dur)

你可以查看文件

适用于其他操作系统（Linux、Mac等）

插入环

import winsound
if category_index=='index of knife':
    windsound.beep(duration(ms),frequency)
else:
    pass

谢谢回复，我已经导入了pygame，但是我不知道为什么我将结果和pygame结合起来，它不能正常工作

import winsound
if category_index=='index of knife':
    windsound.beep(duration(ms),frequency)
else:
    pass
