Description

This paper presents a brief introduction about text-to-spcech (TTS) systems, its main structure and alternatíves. In a more specific way, it was developed three algorithms of a system that automatic reads numbers. Each algorithm hás its own functions and its own way to approach the problem. The algorithms have been programmed using Matiab sofhvare. The audio signals have been recorded and edited using Praat software. Finally a perceptual evaluation was made on each algorithm and was assigned a rating to each one. Generally, thc MOS gives a very good levei ofclassification for the three algorithms.
