- Verfahren zur Graphem-Phonem-Konvertierung eines Wortes, das als Ganzes nicht in einem Aussprachelexikon enthalten ist, mit folgenden Schritten:a) das Wort wird in Teilwörter zerlegt,b) eine Graphem-Phonem-Konvertierung der Teilwörter wird durchgeführt,c) die durch die Konvertierung erhaltenen Transkriptionen der Teilwörter werden hintereinander aufgereiht, wobei sich mindestens eine Schnittstelle zwischen den Transkriptionen der Teilwörter ergibt,d) die an die mindestens eine Schnittstelle grenzenden Phoneme der Teilwörter werden bestimmt,e) es werden diejenigen Grapheme der Teilwörter bestimmt, die die an die mindestens eine Schnittstelle grenzenden Phoneme erzeugen, mit Hilfe eines Lexikons, das angibt, durch welche Grapheme die Phoneme erzeugt wurden,f) die Graphem-Phonem-Konvertierung der bestimmten Grapheme wird in Abhängigkeit des linken und rechten Kontextes der jeweiligen Schnittstelle mittels eines Neuronalen Netzes neu berechnet.
- Verfahren nach Anspruch 1,
dadurch gekennzeichnet, dass für das Wort in einer Datenbank, die phonetische Transkriptionen von Wörtern enthält, nach Teilwörtern des Worts gesucht wird; und- dass für ein in der Datenbank gefundenes Teilwort die in der Datenbank verzeichnete phonetische Transkription gewählt wird. - Verfahren nach Anspruch 2,
dadurch gekennzeichnet, dass das Wort neben dem gefundenen Teilwort mindestens einen weiteren Bestandteil aufweist, der nicht in der Datenbank verzeichnet ist; und- dass dieser weitere Bestandteil mittels einer OOV-Behandlung phonetisch transkribiert wird. - Verfahren nach einem der vorhergehenden Ansprüche,
dadurch gekennzeichnet, dass das Wort in Teilwörter einer gewissen Mindestlänge zerlegt wird. - Computerprogrammprodukt, das durch einen Computer ausführbar ist und dabei die Schritte nach einem der Ansprüche 1 bis 4 ausführt.
- Computerprogrammprodukt, das auf einem computergeeigneten Medium gespeichert ist und computerlesbare Programmmittel umfaßt, die es einem Computer ermöglichen, das Verfahren nach einem der Ansprüche 1 bis 4 auszuführen.
- Datenträger, auf dem ein Computerprogramm gespeichert ist, das es einem Computer ermöglicht, durch einen Ladeprozess das Verfahren nach einem der Ansprüche 1 bis 4 auszuführen.
- Computersystem mit Mitteln zum Ausführen des Verfahrens nach einem der Ansprüche 1 bis 4.
- Computersystem zur Graphem-Phonem-Konvertierung eines Worts, das als Ganzes nicht in einem Aussprachelexikon enthalten ist,einer Speichereinrichtung (22, 30) zum Speichern eines Computerprogramms auf einem Speichermedium;einer Verarbeitungseinheit (20) zum Laden des Computerprogramms aus der Speichereinrichtung und zum Ausführen des Computerprogramms;mit Mitteln zum Zerlegen des Worts in Teilwörter;mit Mitteln zum hintereinander Aufreihen der Transkriptionen der Teilwörter, wobei sich mindestens eine Schnittstelle zwischen den Transkriptionen der Teilwörter ergibt;mit Mitteln zum Bestimmen der an die mindestens eine Schnittstelle grenzenden Phoneme der Teilwörter;mit Mitteln zum Bestimmen derjenigen Grapheme der Teilwörter, die die an die mindestens eine Schnittstelle grenzenden Phoneme erzeugen, mit Hilfe eines Lexikons, das angibt, durch welche Grapheme die Phoneme erzeugt wurden;mit Mitteln zum erneuten Berechnen der Graphem-Phonem-Konvertierung der bestimmten Grapheme in Abhängigkeit des linken und rechten Kontextes der jeweiligen Schnittstelle mittels eines Neuronalen Netzes; undmit Mitteln zum anschließenden Schreiben der an der Schnittstelle neu berechneten Phoneme in eine zweite Speichereinrichtung.
