Abstract:
1. A method comprising: creating a decision tree for pronunciation modelling application for efficient representation in an electronic memory of an electronic device, said decision tree comprising a parent node and at least one leaf node, said creating the decision tree further including arranging said nodes in the decision tree such that said nodes comprise at least one datum that has been coded according to a coding method that provides minimum bits for said datum, said at least one datum corresponding to a phoneme in a specific context, the specific context being defined by at least one data of a parent node also corresponding to a phoneme, mapping the nodes of said decision tree sequentially to an array in such a manner that nodes follow the parent node in storage order without a link from their parent node, and mapping the array to a memory structure stored in a computer readable medium to be used for text-to-phoneme translation.
