Method and system for determining available and alternative speech commands
A method and system for use with a computer speech recognition system to efficiently identify valid system commands to users. The method involves a series of steps including: receiving data representative of a speech recognition system user input; comparing the data to a grammar defined for the speech recognition system to determine whether the data is representative of a user input which is a valid system command; and notifying the user as to whether the data is representative of a valid system command. The process can also involve the additional steps of determining a functional expression for the data; and comparing the functional expression to a set of all functional expressions permitted in the grammar to identify any alternate user inputs for producing the functional expression.
