First Claim
Patent Images
1. A method for verifying a speaker by a computer, comprising:
- randomly selecting a code word by assembling previously stored syllable units, the syllable units having been previously supplied by the speaker;
allowing a speaker to utter a code word, the code word having at least two syllable units with at least one syllable unit being a component of another code word;
comparing the code word uttered by the speaker with a pattern formed of previously stored syllable units having been previously supplied by the speaker; and
verifying the speaker only if the pattern matches the uttered code word with a predetermined minimum quality.

Abstract
A method for verifying a speaker by a computer is specified in which the speaker utters at least one code word consisting of a random combination of syllable units previously supplied by the speaker. A comparison of this uttered code word with at least one pattern verifies the speaker if the at least one pattern matches the uttered code word with a predetermined minimum quality. The code word is designed in such a manner that it has at least two syllable units, at least one syllable unit being a component of a further code word.

21. A method for training patterns for verifying a speaker, comprising:
-
allowing the speaker to speak a plurality of words; automatically segmenting the words into syllable units; storing the syllable units; randomly selecting a code word by assembling the syllable units having been previously supplied by the speaker to form the code word; and using the code word, including the syllable units having been previously supplied by the speaker, to verify the speaker. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A computer readable medium storing a program for controlling a computer to perform a method comprising:
-
allowing a speaker to utter at least one code word, the code word having at least two syllable units with at least one syllable unit being a component of another code word; comparing the code word uttered by the speaker with at least one pattern formed of previously stored syllable units, the syllable units having been previously supplied by the speaker; and verifying the speaker only if the at least one pattern matches the uttered code word with a predetermined minimum quality, wherein the code word is randomly selected by assembling the previously stored syllable units having been previously supplied by the speaker.
