1. A method of determining database entries of a database using an automatic dialog system, the method comprising:
- temporarily storing speech input,processing speech input using an automatic speech recognition device and generating a speech recognition result using a first lexicon, wherein the first lexicon comprises a first set of lexicon entries, and each lexicon entry contains at least one acoustic reference, which corresponds to a Hidden Markov Model,searching the database for a database entry corresponding to the speech recognition result,after the searching, and in a case where no database entry is found, adapting the first lexicon to include a second set of lexicon entries without additional user input, wherein the second set of lexicon entries differs from the first set of lexicon entries by at least one lexicon entry, and repeating the processing and the searching using the temporarily stored speech input and the adapted first lexicon; and
wherein, in a case where a database entry is found, outputting.

Abstract
The invention relates to a method of determining database entries of a database (9) by means of an automatic dialog system (1) in which the following steps are provided:
- 1.1 temporary storage of a speech input,
- 1.2 processing of the speech utterance by means of an automatic speech recognition device (4) and generation of a speech recognition result using a first lexicon (6) which has a first set of lexicon entries, where a lexicon entry contains at least one acoustic reference,
- 1.3 search for a database entry corresponding to the speech recognition result,
- 1.4 for the case where no database entry is found in step 1.3,
- adaptation of the first lexicon (6) so that the first lexicon (6) has a second set of lexicon entries which differs from the first set of lexicon entries by at least one lexicon entry,
- repetition of steps 1.2 and 1.3 using the temporarily stored speech utterance and the adapted first lexicon (6).

9. An automatic dialog system for determining database entries of a database, said system including a plurality of system components for carrying out the following steps:
-
temporarily storing of a speech utterance to be input, processing of the speech utterance using an automatic speech recognition device and generating a speech recognition result using a first lexicon, said first lexicon including a first set of lexicon entries, and wherein each lexicon entry comprises at least one acoustic reference, which corresponds to a Hidden Markov Model, searching for a database entry corresponding to the speech recognition result, after the searching, and, in a case where no database entry is found, adapting the first lexicon to include a second set of lexicon entries without additional user input, wherein the second set of lexicon entries differs from the first set of lexicon entries by at least one lexicon entry, and repeating the processing and the searching using the temporarily stored speech utterance and the adapted first lexicon; and wherein, in a case where the database entry is found, outputting.
