1. A method comprising: receiving, at a computing device, information indicating a plurality of actions that a given application is configured to perform, wherein the information indicating each respective action of the plurality of actions includes one or more parameters that are used to enable the given application to perform the respective action; receiving, at the computing device, for each respective action, one or more example instructions that, when recognized by the given application, causes the given application to perform the respective action, wherein the one or more example instructions comprise natural language; based on the one or more example instructions for each respective action, the plurality of actions, and the one or more parameters included for each respective action, the computing device determining a plurality of candidate instructions for each respective action that, when recognized by a voice interface of the given application, causes the given application to perform the respective action, wherein each candidate instruction of the plurality of candidate instructions comprises one or more grammars recognizable by the voice interface of the given application; receiving, at the computing device, a plurality of acceptance information comprising, for each candidate instruction, respective acceptance information indicative of whether the candidate instruction is applicable to the respective action, wherein the plurality of acceptance information indicates, for each respective action of at least one of the plurality of actions, that at least one of the plurality of candidate instructions determined for the respective action is rejected; based on the plurality of acceptance information, storing, at the computing device, for each candidate instruction, a respective identifier associated with the candidate instruction and indicative of whether the candidate instruction is rejected; the computing device comparing at least a portion of the respective acceptance information with a stored acceptance information log so as to determine a correlation between the respective acceptance information and the stored acceptance information log, wherein the stored acceptance information log comprises a plurality of predetermined acceptance information associated with a plurality of predetermined example instructions; and based on the correlation, the computing device referring to the stored identifiers to determine a set of instructions that are recognizable by the voice interface and that, when recognized by the voice interface, causes the given application to perform one or more of the plurality of actions, wherein determining the set of instructions comprises, for each respective action, (i) selecting, based on the stored identifiers, one or more of the plurality of candidate instructions for the respective action to be included in the set of instructions and (ii) selecting, based on the stored identifiers, the at least one rejected candidate instruction for the respective action to not be included in the set of instructions and to not be recognizable by the voice interface to cause the given application to perform the respective action.
