Abstract:     A speech recognition system which interprets speech queries such as help queries and presents a list of relevant proposed commands sorted in order based upon relevance of the commands. The system organizes the displayed commands being prompted to the user through probability determining means which for each of a predetermined plurality of speech commands store an associated set of speech terms, each term having relevance to its associated command combined with means responsive to a speech query for determining the probability of speech terms from said set in said query, and means responsive to said probability determining means for prompting the user with a displayed sequence of commands sorted based upon said probability of speech terms associated with said commands. When such a sorted command is selected, the system has means responsive to a speech command for carrying out the system action corresponding to the command.The system also provides means for adding terms to previous speech terms wherein the probability determining means will redetermine probability to include such added terms. In such a situation, the probability determining means will redetermine the weights to include the additional weights of such added terms.

First Claim:
Show all 15 claims
What is claimed is:     1. In a user interactive computer controlled display system with speech command input recognition comprising, apparatus for interpreting speech queries to locate commands comprising:
  • means for predetermining a plurality of speech commands each associated with a corresponding plurality of system actions,
  • means responsive to a speech command for carrying out the system action corresponding to the command,
  • means for storing for each of said plurality of commands, an associated set of speech terms, each term having relevance to its associated command,
  • means responsive to a speech query for determining the probability of speech terms from said set in said query by applying a weight factor for a firm recognition of a speech term at least twice the weight of an infirm recognition of the term, and
  • means responsive to said probability determining means for prompting the user with a displayed sequence of commands sorted based upon said probability of speech terms associated with said commands.
