One and four types of asymmetric discrete envelope soliton solutions are found for semi-discrete sine-Gordon equation and semi-discrete wave equation with cubic nonlinearity. They are found by appropriately transforming the variables of already-known discrete envelope soliton solutions. Some properties of these solutions are discussed.
