SYSTEM AND METHOD FOR CORRECTING SPEECH INPUT

1 . A system comprising:

a data processor; and

a speech input processing module, executable by the data processor, the speech input processing module being configured to:

receive a base input string;

detect a correction operation;

receive a replacement string in response to the correction operation;

generate a base object set from the base input string and a replacement object set from the replacement string;

identify a matching base object of the base object set that is most phonetically similar to a replacement object of the replacement object set; and

replace the matching base object with the replacement object in the base input string.

2 . The system of claim 1 wherein the base input string is received as a spoken utterance.

3 . The system of claim 1 wherein the correction operation is explicitly initiated by use of an input mechanism from the group consisting of: clicking an icon, activating a softkey, pressing a physical button, providing a keyboard input, manipulating a user interface, and uttering a separate audible command.

4 . The system of claim 1 wherein the correction operation is implicitly initiated by detection of a speaker audibly spelling out a word or phrase.

5 . The system of claim 1 wherein the replacement is received as a spoken utterance.

6 . The system of claim 1 being further configured to generate a phonetic representation of each of a plurality of objects in the base object set.

7 . The system of claim 1 being further configured to generate a phonetic representation of each of a plurality of objects in the replacement object set.

8 . The system of claim 1 being further configured to generate a difference score between each of a plurality of objects in the base object set and each of a plurality of objects in the replacement object set.

9 . The system of claim 1 wherein the speech input processing module is included in an application (app) executed on a platform from the group consisting of: a mobile device, an in-vehicle control system, and a network service in a network cloud.

10 . A method comprising:

receiving a base input string;

detecting a correction operation;

receiving a replacement string in response to the correction operation;

generating a base object set from the base input string and a replacement object set from the replacement string;

identifying a matching base object of the base object set that is most phonetically similar to a replacement object of the replacement object set; and

replacing the matching base object with the replacement object in the base input string.

11 . The method of claim 10 wherein the base input string is received as a spoken utterance.

12 . The method of claim 10 wherein the correction operation is explicitly initiated by use of an input mechanism from the group consisting of: clicking an icon, activating a softkey, pressing a physical button, providing a keyboard input, manipulating a user interface, and uttering a separate audible command.

13 . The method of claim 10 wherein the correction operation is implicitly initiated by detection of a speaker audibly spelling out a word or phrase.

14 . The method of claim 10 wherein the replacement string is received as a spoken utterance.

15 . The method of claim 10 including generating a phonetic representation of each of a plurality of objects in the base object set.

16 . The method of claim 10 including generating a phonetic representation of each of a plurality of objects in the replacement object set.

17 . The method of claim 10 including generating a difference score between each of a plurality of objects in the base object set and each of a plurality of objects in the replacement object set.

18 . The method of claim 10 wherein the method is performed by an application (app) executed on a platform from the group consisting of: a mobile device, an in-vehicle control system, and a network service in a network cloud.

19 . A non-transitory machine-useable storage medium embodying instructions which, when executed by a machine, cause the machine to:

receive a base input string;

detect a correction operation;

receive a replacement string in response to the correction operation;

generate a base object set from the base input string and a replacement object set from the replacement string;

identify a matching base object of the base object set that is most phonetically similar to a replacement object of the replacement object set; and

replace the matching base object with the replacement object in the base input string.

20 . The machine-useable storage medium as claimed in claim 19 wherein the instructions are included in an application (app) executed on a platform from the group consisting of: a mobile device, an in-vehicle control system, and a network service in a network cloud.
