Patent Document ID: 8359204
Application ID: 12259196

Base Claim:
1. A computer-implemented method for classifying speech data including one or more words, the method comprising the steps of: storing a plurality of predefined commands, each predefined command including one or more words and each predefined command associated with an action; receiving one or more alternate formats associated with each predefined command from a data source, each alternate format including one or more words and an identifier associating the alternate format with a predefined command; for each predefined command, representing the predefined command with a sparse vector comprising the term frequency-inverse document frequency (“TFIDF”) weights for each word of the predefined command and the one or more alternate formats associated with the predefined command; receiving the speech data; generating a term frequency vector associated with the speech data; determining, for each predefined command, the probability that the speech data is associated with the predefined command based on the sparse vector associated with each predefined command and the term frequency vector associated with the speech data; associating the speech data with a predefined command based on the determined probabilities; and executing the action associated with the predefined command associated with the speech data.

Claim 9:
9. The computer-implemented method of claim 1 , wherein associating the speech data with a predefined command comprises: determining a largest probability associated with a first predefined command; determining a second largest probability associated with a second predefined command; calculating a difference between the largest probability and the second largest probability; responsive to the difference not exceeding a threshold value, generating a request for an input selecting the first predefined command or the second predefined command; and associating the speech data with the first predefined command or the second predefined command responsive to the input.
