Abstract:
1. A method for speech synthesis by a grapheme/phoneme conversion, comprising: searching for subwords of a given word in a database which contains phonetic transcriptions of words, the given word having a subword registered in the database, and a further constituent which is not registered in the database; selecting a phonetic transcription from the database for the subword; phonetically transcribing the further constituent of the given word with the aid of an out-of-vocabulary (OOV) treatment, the out-of-vocabulary (OOV) treatment of the further constituent being performed based on phonetic context, as a function of the phonetic transcription of the subword; and combining the phonetic transcription of the subword and the phonetic transcription of the further constituent, wherein the out-of-vocabulary (OOV) treatment for phonetic transcription of the further constituent is performed by a neuron network, the given word has at least first and second subwords registered in the database, a search is made for both the first and second subwords in the database, a phonetic transcription is selected from the database for both the first and second subwords, the phonetic transcription of the first and second subwords and the phonetic transcription of the further constituent are combined, the further constituent in the given word is arranged between the first subword and the second subword, and the out-of-vocabulary (OOV) treatment for phonetic transcription of the further constituent is performed as a function of the phonetic transcription of the first subword and the phonetic transcription of the second subword.
