WHAT IS THE TEXT-TO-SPEECH SYNTHESIS?
The artificial sound generation has always been an interesting research area both in the past and present. In early stages, it had been considered in such applications which provide support mainly for blinds, it has now found a number of application areas. In fact, the idea of manufacturing a talking machine is not new at all; one could say that the last quarter of the 20th century became a successful period when the fruits of such a long-term effort had been obtained.
