Dealing with salt&pepper and speckle noises

Hello, I have to add speckle and salt&pepper noises to my image. I know that medfilt2 filter is good when you're dealing with salt&pepper, but what about speckle noise? My grade is based on how low "sse" will be, and it is still pretty high :/

if true
     img = imread('liftingbody.png');
  img = double(img)/255;
  multinoise = imnoise(img, 'speckle', 0.1);
  noised = imnoise(multinoise, 'salt & pepper');

    result = wiener2(noised,[3,3]);
    result = wiener2(result,[3,3]);

    result = medfilt2(result, [3,3],'symmetric');
    mask = ones(3)/9;
    for k=1:50
    result = imfilter(result,mask,'replicate');
    end

    mask1 = [-1 -1 -1 ; -1 9 -1; -1 -1 -1];
    for k=1:6
    result = imfilter(result, mask1, 'replicate');
    end
    sse = sqrt(sum(sum((img-result).^2)));

    figure;
    subplot(131); imshow(img); title('Oryginalny');
    subplot(132); imshow(noised); title('Zaszumiony');
    subplot(133); imshow(result); title('Przefiltrowany');
  end
