13. A system for eliciting command variants from crowd users to train a natural language processing system comprising: a memory; one or more physical processors programmed with one or more computer program instructions which, when executed, cause the one or more physical processors to: identify a computer recognized command to be processed by a computer; generate at least a first task, wherein the first task includes command creation instructions that prompt a user to input a variant of the computer recognized command; transmit the first task to a plurality of users via a network; receive, from at least a first user among the plurality of users, a first user-defined variant of the computer recognized command; receive, from at least a second user among the plurality of users, a second user-defined variant of the computer recognized command; and store the first user-defined variant and the second user-defined variant in association with the computer recognized command; generate at least a second task, wherein the second task includes command review instructions that prompt a given user to verify the first user-defined variant; transmit the second task to a second plurality of users via the network; receive, from at least a second user among the second plurality of users, a verification of the first user-defined variant; and train the natural language processing system to recognize variants of the computer recognized command based on the verified first user-defined variant and the second user-defined variant.

The system of claim 13 , wherein to store the first user-defined variant and the second user-defined variant, the one or more physical processors are further cause to store the first user-defined variant and the second user-defined variant in a transcription library.
