Voice command processing system and computer therefor, and voice command processing method

A computer, for executing a user issued voice command, comprising:

• a registration unit for registering a command executable by said computer;
• a voice command processor for accepting a user issued voice command, and for performing a process to execute said voice command;
• a speech recognition engine for analyzing, as a sentence, said voice command accepted by said voice command processor;
• and
• a similarity calculator for comparing said sentence analyzed by said speech recognition engine with said command registered in said registration unit, and for calculating for said voice command a similarity.

A voice command processing method that permits a computer to perform a user issued voice command comprising the steps of:

• accepting a user issued voice command;
• determining whether said voice command can be identified as a previously registered command;
• analyzing said voice command as a sentence when it is impossible for said voice command to be identified as a registered command;
• and
• comparing phrases in said analyzed sentence with phrases in said registered command in order to calculate a similarity.

A voice command processing method that permits a computer to execute a user issued voice command comprising the steps of:

• analyzing as a sentence a user issued voice command;
• and
• comparing said voice command (W1), analyzed as a sentence, with a command (W2) registered in advance to calculate a similarity S(W1,W2),
• whereby said similarity S(W1,W2) is represented by a value obtained by dividing, by the number (Vn) of applicable words for the calculation of said similarity S(W1,W2), the sum of scores (s) that is based on matching the i-th word (w1(i)) of said voice command and the j-th word (w2(j)) of said registered command.

A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

• accepting a user issued voice command;
• determining whether said voice command can be identified as a previously registered command;
• analyzing said voice command as a sentence when it is impossible for said voice command to be identified as a registered command;
• and
• comparing phrases in said analyzed sentence with phrases in said registered command in order to calculate a similarity.
