Abstract
The invention relates to an operating method for an automated language recognizer intended for the speaker-independent language recognition of words from different languages, particularly for recognizing names from different languages. The method is based on a language defined as the mother tongue and has an input phase for establishing a language recognizer vocabulary. Phonetic transcripts are determined for words in various languages in order to obtain phoneme sequences for pronunciation variants The phonemes of each relevant phoneme set of the mother tongue are then specifically mapped to determine phoneme sequences that correspond to pronunciation variants.

12. A method for automated language recognition of words from different languages said method comprising the steps of:
-
(a) loading a phoneme set associated with a language specified as a mother tongue into a mother tongue language recognizer;
(b) determining the phonetic transcripts of each word for N various languages not specified as the mother tongue to obtain N first phoneme sequences for each word corresponding to N first pronunciation variants;
(c) calculating a phoneme map by mapping the first phoneme sequences of each of said N languages to a relevant phoneme set of the mother tongue;
(d) determining N second phoneme sequences corresponding to N second pronunciation variants from said phoneme map for each word; and
(e) processing said N second phoneme sequences with the phoneme set associated with the language specified as a mother tongue to identify matching or similar words. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An automatic language recognizing apparatus, receiving words from various languages, comprising:
-
a mother tongue language recognizer, said recognizer storing a phoneme set of a predetermined mother tongue;
a first processing module for determining the phonetic transcripts of words from N various languages in order to obtain N first phoneme sequences for each word corresponding to N first pronunciation variants;
a second processing module for implementing a mapping of the phonemes of each of N language to a particular phoneme set of the mother tongue;
a third processing module for applying the mapping, implemented by means of the second processing module, to the N first phoneme sequences for each word determined by means of the first processing module, with N second phoneme sequences corresponding to N second pronunciation variants being obtained per word, that can be recognized by means of the mother tongue language recognizer; and
a fourth processing module for creating a language recognizable vocabulary with the N second phoneme sequences per word, obtained by the third processing module, for the mother tongue language recognizer. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
