1. A method for automatically generating a vocabulary entry from input acoustic data, said method comprising:
- performing, by a computer processor, a vocabulary entry type-specific acoustic phonetic transcription of the input acoustic data and a classification of vocabulary entry types based on phonetic structure, wherein the classification of vocabulary entries is carried out in accordance with a number of predetermined types;
performing, by the computer processor, a vocabulary entry type-specific phoneme-to-grapheme conversion, to derive the respective vocabulary entries comprising a pair of the phonetic transcription of the input acoustic data and its grapheme form; and
providing a select one of the vocabulary entries to a database for use in a speech processing application;
wherein the classification of vocabulary entries is carried out together with the vocabulary entry type-specific acoustic phonetic transcription in a combined step.

8. A device for automatically generating a vocabulary entry from input acoustic data and comprising:
- a vocabulary entry type classifier that determines a vocabulary entry type based on a phonetic structure of the input acoustic data, and
an acoustic phonetic transcriber that provides a phonetic sequence based on the input acoustic data and the vocabulary entry type, a vocabulary entry compositor that generates the vocabulary entry, wherein the vocabulary entry type classifier is arranged to classify the input acoustic data in accordance with a number of predetermined vocabulary entry types, and wherein the vocabulary entry compositor includes a statistical phoneme-to-grapheme converter that generates a grapheme based on the vocabulary entry type; wherein the vocabulary entry type classifier includes gates for respective vocabulary entry types, the gates being arranged to output a respective vocabulary entry type information together with the phonetic transcription. - View Dependent Claims (9, 10, 11, 12)

14. A non-transitory computer readable medium that includes a program that, when executed by a processor, causes the processor to:
-
determine a vocabulary entry type based on a phonetic structure of an input acoustic data, provide a phonetic sequence based on the input acoustic data and the vocabulary entry type, and generate a vocabulary entry based on a statistically determined grapheme based on the phonetic sequence and the vocabulary entry type, wherein determining the vocabulary entry type is determined from among a plurality of predetermined vocabulary entry types, and the plurality of predetermined vocabulary entry types includes a natural language entry type and an abbreviation entry type. - View Dependent Claims (15, 16, 17, 18)
