A transformation can be derived which would represent that processing required to convert a male speech model to a female speech model. That transformation is subjected to a predetermined modification, and the modified transformation is applied to a female speech model to produce a synthetic children's speech model. The male and female models can be expressed in terms of a vector representing key values defining each speech model and the derived transformation can be in the form of a matrix that would transform the vector of the male model to the vector of the female model. The modification to the derived matrix comprises applying an exponential p which has a value greater than zero and less than 1.

On peut dériver une transformation qui représenterait le traitement requis pour convertir un modèle vocal mâle en un modèle vocal femelle. Cette transformation est soumise à une modification prédéterminée, et la transformation modifiée est appliquée à un modèle vocal femelle pour produire un modèle vocal denfant synthétique. Les modèles mâle et femelle peuvent être exprimés en termes de vecteur représentant des valeurs clés définissant chaque modèle vocal et la transformation dérivée peut prendre la forme dune matrice qui transformerait le vecteur du modèle mâle en vecteur de modèle femelle. La modification en matrice dérivée consiste à appliquer un exponentiel p qui a une valeur supérieure à zéro et inférieure à 1.
