1. A method for grapheme-phoneme conversion of a word which is not contained as a whole in a pronunciation lexicon, comprising:
- decomposing the word into subwords;
performing grapheme-phoneme conversion of the subwords to obtain transcriptions of the subwords;
sequencing the transcriptions of the subwords are sequenced to produce at least one interface between the transcriptions of the subwords, determining phonemes of the subwords bordering on the at least one interface;
determining graphemes of the subwords which generate the phonemes bordering on the at least one interface; and
recalculating grapheme-phoneme conversion of the graphemes bordering on the at least one interface.

Abstract
In a method for grapheme-phoneme conversion of a word which is not contained as a whole in a pronunciation lexicon, the word is firstly decomposed into subwords. The subwords are transcribed and chained. As a result, interfaces are formed between the transcriptions of the subwords. The phonemes at the interfaces must be changed frequently. Consequently, they are subjected to recalculation.

-
at least one storage device to store a computer program on a storage medium; and
a processing unit, coupled to the at least one storage device, to load and execute the computer program to decompose the word into subwords, perform grapheme-phoneme conversion of the subwords to obtain transcriptions of the subwords;
