Abstract

A natural language dialogue system and a method capable of correcting a speech response are provided. The method includes following steps. A first speech input is received. At least one keyword included in the first speech input is parsed to obtain a candidate list having at least one report answers. One of the report answers is selected from the candidate list as a first report answer, and a first speech response is output according to the first report answer. A second speech input is received and parsed to determine whether the first report answer is correct. If the first report answer is incorrect, another report answer other than the first report answer is selected from the candidate list as a second report answer. According to the second report answer, a second speech response is output.

Claims

1. A method for correcting a speech response, the method comprising:

receiving a first speech input;

parsing at least one first keyword included in the first speech input to obtain a candidate list, wherein the candidate list has at least one report answer;

selecting one of the at least one report answer from the candidate list as a first report answer and outputting a first speech response according to the first report answer;

receiving and parsing a second speech input to determine whether the first report answer is correct; and

if the first report answer is incorrect, selecting another report answer other than the first report answer from the candidate list as a second report answer and outputting a second speech response according to the second report answer.

2. The method as recited in claim 1, wherein the step of determining whether the first report answer is correct comprises:

parsing the second speech input to obtain a second keyword; and

determining the first report answer is incorrect if the second keyword does not match a user'"'"'s intention in the first report answer.

3. The method as recited in claim 2, wherein the step of selecting the another report answer other than the first report answer from the candidate list as the second report answer comprises:

selecting the another report answer matching the second keyword from the candidate list as the second report answer according to the second keyword.

4. The method as recited in claim 2, wherein the step of selecting the another report answer other than the first report answer from the candidate list as the second report answer further comprises:

outputting a third speech response if the first report answer is incorrect and if the candidate list does not have any report answer matching the second keyword.

5. The method as recited in claim 1, further comprising:

arranging the at least one report answer in the candidate list according to a priority; and

selecting the first report answer from the candidate list according to the priority.

6. The method as recited in claim 5, wherein the step of arranging the at least one report answer in the candidate list according to the priority comprises:

determining the priority of the at least one report answer according to a public usage habit.

7. The method as recited in claim 5, wherein the step of arranging the at least one report answer in the candidate list according to the priority further comprises:

determining the priority of the at least one report answer according to a user'"'"'s preference.

8. The method as recited in claim 5, wherein the step of arranging the at least one report answer in the candidate list according to the priority further comprises:

determining the priority of the at least one report answer according to a user'"'"'s habit.

9. The method as recited in claim 1, wherein the step of selecting the first report answer comprises:

searching a user'"'"'s preference record corresponding to the at least one first keyword of the first speech input from a properties database; and

selecting one of the at least one report answer matching the user'"'"'s preference record as the first report answer.

10. The method as recited in claim 1, wherein the step of selecting the first report answer comprises:

parsing a fourth speech input and obtaining at least one fourth keyword, wherein the fourth speech input is input before the first speech input; and

selecting one of the at least one report answer matching the at least one first keyword and the at least one fourth keyword as the first report answer.

11. The method as recited in claim 1, the method being suitable for a mobile communication apparatus.

12. A natural language dialogue system comprising:

a speech sampling module receiving a first speech input; and

a natural language comprehension system coupled to the speech sampling module, the natural language comprehension system parsing a first keyword included in the first speech input to obtain a candidate list, the candidate list having at least one report answer, the natural language comprehension system selecting one of the at least one report answer from the candidate list as a first report answer and outputting a first speech response according to the first report answer, the speech sampling module receiving a second speech input, the natural language comprehension system parsing the second speech input to determine whether the first report answer is correct, and if the first report answer is incorrect, the natural language comprehension system selects another report answer other than the first report answer as a second report answer and outputs a second speech response according to the second report answer.

13. The natural language dialogue system as recited in claim 12, wherein the natural language comprehension system parses the second speech input to obtain a second keyword, and if the second keyword does not match a user'"'"'s intention included in the first report answer, the natural language comprehension system determines the first report answer is incorrect.

14. The natural language dialogue system as recited in claim 13, wherein the natural language comprehension system selects the second report answer matching the second keyword from the candidate list according to the second keyword.

15. The natural language dialogue system as recited in claim 13, wherein if the first report answer is incorrect and if the candidate list does not have any report answer matching the second keyword, the natural language comprehension system outputs a third speech response.

16. The natural language dialogue system as recited in claim 12, wherein the natural language comprehension system arranges the at least one report answer in the candidate list according to a priority and selects the first report answer from the candidate list according to the priority.

17. The natural language dialogue system as recited in claim 16, wherein the natural language comprehension system determines the priority of the at least one report answer according to a public usage habit.

18. The natural language dialogue system as recited in claim 16, wherein the natural language comprehension system determines the priority of the at least one report answer according to a user'"'"'s preference.

19. The natural language dialogue system as recited in claim 16, wherein the natural language comprehension system determines the priority of the at least one report answer according to a user'"'"'s habit.

20. The natural language dialogue system as recited in claim 16, wherein the natural language comprehension system searches a user'"'"'s preference record corresponding to the first keyword of the first speech input from a properties database and selects one of the at least one report answer matching the user'"'"'s preference record as the first report answer.

21. The natural language dialogue system as recited in claim 16, wherein the natural language comprehension system parses a fourth speech input to obtain a fourth keyword, the fourth speech input is received by the speech sampling module before the first speech input is received, and the natural language comprehension system selects one of the at least one report answer matching the fourth keyword as the first report answer.

22. The natural language dialogue system as recited in claim 12, the natural language dialogue system being suitable for a mobile communication apparatus.
