Abstract

Letter to phoneme conversion is a basic step in Speech Synthesis processes. Traditionally, the activity involves the implementation of rules that define the mapping of letters into sounds. This paper presents results of the application of an evolutionary computation technique (Genetic Programming), in Brazilian Portuguese synthesis, aiming to discover automatically programs implementing specific synthesis rules.
