The present invention relates to a method for manufacturing a strained fermented dairy product comprising the following successive steps: (a) providing a dairy product containing starch, (b) fermenting the dairy product after adding lactic acid bacteria to obtain a fermented dairy product, and (c) separating a liquid whey from the fermented dairy product to obtain a strained fermented dairy product The present invention relates also to the use of starch for preventing the clogging of the separating device used in the preparation of a strained fermented dairy product.The present invention relates to a method for manufacturing a strained fermented dairy product comprising the following successive steps: (a) providing a dairy product containing starch, (b) fermenting the dairy product after adding lactic acid bacteria to obtain a fermented dairy product, and (c) separating a liquid whey from the fermented dairy product to obtain a strained fermented dairy product The present invention relates also to the use of starch for preventing the clogging of the separating device used in the preparation of a strained fermented dairy product. Embodiments are directed to systems, methods, and devices for providing help to a user through an output modality. Embodiments include an analysis logic implemented at least partially in hardware to receive an indication to provide help or other information to the user； identify an availability of one or more output modalities for providing the help； and determine an output modality for providing the help based on the availability of the one or more output modalities. Embodiments also include a dialog system implemented at least partially in hardware to process the request for help； and provide a dialog message in response to the request for help, the dialog message provided on the determined output modality. Some embodiments also include a sensor input for receiving sensory information, wherein the analysis logic identifies the output modal
