A system and method for processing speech input comprising a speech recognizer and a logical command processor which facilitates additional processing of speech input beyond the speech recognizer level. A speech recognizer receives input from a user, and when a command is identified in the speech input, if the command meets conditions that require additional processing, a representation of the speech input s stored for subsequent processing. A logical command processor performs additional processing of command input by analyzing the command and its elements, determining which elements are required for successful processing the command and which elements are present and lacking. The user is prompted to supply missing information, and subsequent user input is added to the command structure until the command input is aborted or the command structure reaches sufficient completeness to enable execution of the command. Thereby, speech input of complex commands in natural language in a system running a plurality of applications and processes is made possible.
