Speckle noise is a multiplicative noise, where the images is multiplied element by element by a matrix of uniformly distributed (not Gaussian) noise with 0 mean and some variance.
Gaussian noise (which has a different distribution than speckle noise) is usually used as additive noise, i.e. the noise matrix is added to the image matrix.
