  • Abstract: In this work, a system to translate portuguese language text spoken in brazil into speech is developed. The method adopted for translation is text-phoneme-speech. This method has some advantages: (i) it creats a speech library (sl) for any language or for all, independently of text-to-phoneme mapping; (ii) it can interlink with other systems which would to the same task. The use of talker system - maquina falante - is very diversified. People can use easily the computers, because they become more interactive. The technique utilized to map text into phonemes has been the artificial neural networks (ann). The use of ann has some advantages over conventional techniques - like phonetic dictionary: (i) the quantity of information stored by ann is smaller than the quantity of information stored by other techniques; (ii) the user does not need to make maintenance for new words; (iii) multi-layer perceptron has the generalization characteristic. For a good generalization, the training set must characterize all the universe of mapping. For synthesis, we codified the human speech by waveform technique. This technique has been chosen because it is simple and its feature of quality is very relevant. The sl is a set of information about how a synthesis process physically produces phonemes or group of phonemes. Each file of sl represents a syllable
