Method, system, and computer readable medium for comparing phonetic similarity of return words to resolve ambiguities during voice recognition

A system, comprising:

• a memory configured to store logic instructions;
• and
• a processor configured to execute the logic instructions that when executed cause the logic instructions to:
• select a return value corresponding to a spoken input;
• generate a subset of alternative return values for the spoken input, wherein each alternative return value is related to the selected return value based on one of a synonym relationship and a phonetic similarity threshold between a grammar for the return value and the alternative return value;
• generate a first string in a pair of strings is from the grammar for a first return value, and a second string in the pair of strings is from the grammar for a second return value and is not in the grammar for the first return value, then selecting the second string as a likely alternative for the first return value, and constructing the subset of return values that are likely alternatives for each return value in a dictionary;
• and
• present the alternative return values to a user for selection, wherein the user is notified of each string that has a likelihood of being confused.

A non-transitory computer-readable medium, having stored thereon a sequence of instructions, which when executed by a computer processor, cause the computer processor to perform:

• generating a dictionary comprising return values;
• generating a grammar for each return value in the dictionary;
• for each return value in the dictionary, analyzing the grammar to determine a subset of return values from the dictionary that are likely alternatives for the return value comprising for each string in the grammar for the return value, comparing each string with every other string in the dictionary that is not in the grammar for that return value and if said comparison indicates that the strings are related based on one of a phonetic similarity threshold and a synonym relationship then adding the return value associated with the other string to the subset;
• when a first string in a pair of strings is from the grammar for a first return value, and a second string in the pair of strings is from the grammar for a second return value and is not in the grammar for the first return value, then selecting the second string as a likely alternative for the first return value, and constructing the subset of return values that are likely alternatives for each return value in the dictionary;
• and
• if the return value is not confirmed by a user, then presenting the return values in the subset for the first return value at once to the user for selection, wherein the user is notified of each string that has a likelihood of being confused so that the user can make changes to the grammar.

A system, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions which when executed by the processor, cause the computer processor to perform:
• generating a dictionary comprising return values,
• generating a grammar for each return value in the dictionary;
• for each return value in the dictionary, analyzing the grammar to determine a subset of return values from the dictionary that are likely alternatives for the return value, comprising for each string in the grammar for the return value, comparing each string with every other string in the dictionary that is not in the grammar for that return value and if said comparison indicates that the strings are related based on one of a phonetic similarity threshold and a synonym relationship then adding the return value associated with the other string to the subset,
• when a first string in a pair of strings is from the grammar for a first return value, and a second string in the pair of strings is from the grammar for a second return value and is not in the grammar for the first return value, then selecting the second string as a likely alternative for the first return value, and constructing the subset of return values that are likely alternatives for each return value in the dictionary, and
• if the return value is not confirmed by a user, then presenting the return values in the subset for the first return value at once to the user for selection, wherein the user is notified of each string that has a high likelihood of being confused so that the user can make changes to the grammar.

A non-transitory computer-readable storage medium, having stored thereon, a sequence of instructions which when executed by a computer processor, cause the computer processor to perform:

• selecting a return value corresponding to a spoken input;
• generating a subset of alternative return values for the spoken input, wherein the alternative return value is related to the selected return value based on one of a synonym relationship and a phonetic similarity threshold return value based on one of a synonym relationship and a phonetic similarity threshold between the grammars for the return value and the alternative return value;
• generating a first string in a pair of strings is from the grammar for a first return value, and a second string in the pair of strings is from the grammar for a second return value and is not in the grammar for the first return value, then selecting the second string as a likely alternative for the first return value, and constructing the subset of return values that are likely alternatives for each return value in a dictionary;
