Abstract

A method and a device recognizes predefined keywords in spoken language. The keywords is modeled for the recognition process. Furthermore, a predefined set of filler words is modeled. If a keyword occurs in the spoken language, this keyword is recognized, otherwise no keyword is recognized if correspondence with a filler word is determined in the spoken language.

Claims

1. A method for recognizing a set of predefined keywords in spoken language with a computer, which comprises:

a) predefining a set of filler words;

b) modeling a predefined keyword;

c) recognizing the keyword occurring in spoken language;

d) determining a filler word in the spoken language and not recognizing a keyword; and

e) recognizing a predefined set of keywords, the set of keywords taking into account the predefined filler words.

2. The method according to

claim 1

, wherein the predefined set of filler words is smaller than fifty words.

3. The method according to

claim 1

, wherein the predefined set of filler words is determined from a predefined number of most frequently used words of a language.

4. The method according to

claim 1

, including:

deleting a filler word, which is a keyword, from the set of filler words when the predefined set of keywords changes.

5. The method according to

claim 1

, including:

deleting a filler word from the set of filler words if the filler word corresponds to a part of a keyword.

6. The method according to

claim 1

, including:

deleting a filler word from the set of filler words if the filler word is acoustically similar to a part of a keyword.

7. The method according to

claim 1

, including:

displaying the keywords recognized in the spoken language; and

not displaying the recognized filler words.

8. The method according to

claim 1

, including:

modeling a noise of a language to form a modeled noise; and

adding the modeled noise to the set of filler words.

9. The method according to

claim 1

, including:

modeling a pause to form a modeled pause; and

adding the modeled pause to the set of filler words.

10. The method according to

claim 1

, including:

controlling a medical apparatus with a keyword.

11. The method according to

claim 1

, including:

predefining actions to be completed by a computer, the actions occurring when a keyword is input to the computer.

12. The method according to

claim 1

, including:

controlling a communications technology with a keyword.

13. The method according to

claim 1

, including:

controlling an application with a keyword.

14. The method according to

claim 1

, including:

programming a code word indicating that a keyword follows.

15. The method according to

claim 14

, wherein the code word is modeled as a filler word.

18. The method according to

claim 14

, wherein the predefined set of filler words is composed from a predefined number of the most frequently used words of a language.

16. A device for recognizing at least one set of predefined keywords in spoken language, comprising:

a processor unit programmed to

a) predefine a set of filler words;

b) model a predefined keyword for a recognition process;

c) recognize a keyword if the keyword is input;

d) recognize no keyword if correspondence with a member of the set of filler words is determined in the spoken language; and

e) recognize another predefined set of keywords taking into account the predefined filler words.

17. The device according to

claim 16

, wherein the predefined set of filler words is small.
