Abstract

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software that is operable to disambiguate text input. The device is structured to identify and output representations of language objects that are stored in the memory and that correspond with a text input. The device is additionally structured to identify and output representations of language objects that are stored in the memory and that correspond with a known spelling substitution particular to a language active on the handheld electronic device.

Claims

1. A method of enabling an input into a handheld electronic device, the method comprising:

receiving data associated with one or more input key selections;

determining a set of characters based, at least in part, on the received data;

determining a known spelling substitution corresponding to a subset of the set of characters;

determining that a language object stored in memory corresponds to the known spelling substitution; and

outputting the set of characters based, at least in part, on the determination that a language object stored in memory corresponds to the known spelling substitution.

2. The method of claim 1, wherein the received data is in a predetermined language, the method further comprising determining as the known spelling substitution a spelling substitution specific to the predetermined language.

3. The method of claim 2, further comprising detecting a selection of the predetermined language.

4. The method of claim 1, further comprising failing to find a language object stored in memory corresponding to the set of characters and, responsive thereto, initiating the determination of the known spelling substitution.

5. The method of claim 1, wherein the received data is associated with an ambiguous input.

6. A handheld electronic device, comprising:

a processor;

memory storing instructions which, when executed by the processor, cause the handheld electronic device to perform operations comprising;

receiving data associated with one or more input key selections;

determining a set of characters based, at least in part, on the received data;

determining a known spelling substitution corresponding to a subset of the set of characters;

determining that a language object stored in memory corresponds to the known spelling substitution; and

outputting the set of characters based, at least in part, on the determination that a language object stored in memory corresponds to the known spelling substitution.

7. The handheld electronic device of claim 6, wherein the received data is in a predetermined language, wherein said instructions, when executed by the processor, further cause the handheld electronic device to perform operations comprising:

determining as the known spelling substitution a spelling substitution specific to the predetermined language.

8. The handheld electronic device of claim 6, further comprising detecting a selection of the predetermined language.

9. The handheld electronic device of claim 6, wherein said instructions, when executed by the processor, further cause the handheld electronic device to perform operations comprising:

failing to find a language object stored in memory corresponding to the set of characters and, responsive thereto, initiating the determination of the known spelling substitution.

10. The handheld electronic device of claim 6, wherein the received data is associated with an ambiguous input.

11. A non-transitory computer-readable medium comprising instructions which, when executed by a processor, cause the processor to perform operations comprising:

receiving data associated with one or more input key selections;

determining a set of characters based, at least in part, on the received data;

determining a known spelling substitution corresponding to a subset of the set of characters;

determining that a language object stored in memory corresponds to the known spelling substitution; and

outputting the set of characters based, at least in part, on the determination that a language object stored in memory corresponds to the known spelling substitution.

12. The non-transitory computer-readable medium of claim 11, wherein the received data is in a predetermined language, wherein said instructions, when executed by the processor, further cause the processor to perform operations comprising:

determining as the known spelling substitution a spelling substitution specific to the predetermined language.

13. The non-transitory computer-readable medium of claim 11, further comprising detecting a selection of the predetermined language.

14. The non-transitory computer-readable medium of claim 11, wherein said instructions, when executed by the processor, further cause the processor to perform operations comprising:

failing to find a language object stored in memory corresponding to the set of characters and, responsive thereto, initiating the determination of the known spelling substitution.

15. The non-transitory computer-readable medium of claim 11, wherein the received data is associated with an ambiguous input.
