Abstract
A method and a device (1) for automatically generating vocabulary entry from input acoustic data (3), comprising a vocabulary entry type-specific acoustic phonetic transcription module (2; T) and a classifier module (6; 6′) for the classification of vocabulary entry types on the basis of the phonetic structure, wherein the classification of vocabulary entries is carried out in accordance with a number of predetermined types; and vocabulary entry type-specific phoneme-to-grapheme conversion means (28), to derive the respective vocabulary entries comprising a pair of a phonetic transcription and its grapheme form.

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.
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.
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.
