CENTERIS 2014 - Conference on ENTERprise Information Systems / ProjMAN 2014 - International Conference on Project MANagement / HCIST 2014 - International Conference on Health and Social Care Information Systems and Technologies Reading Numbers Algorithm for Portugues e

The paper presents an algorithm for read common numbers until one million in Portuguese language. The record and cutting process of the numbers speech sounds deserved a special attention to improve the speech sound output. A special attention is required for the correct inclusion of particles to provide better naturalness of the read numbers. T he system has the ability of simulate the human biologic speech sound production in the task of reading numbers. The system is based on biologic speech. The naturalness of the system can be improved using speech fil es of read numbers in different position (beginning, middle and end) and using numbers concatenated with the particle ‘e’. A final F0 modification can improve the final speech quality of the system.
