5th International Conference on Spoken Language Processing
Through the years we developed several TTS systems for the Romanian language, each of them presenting some advantages and disadvantages . Taking into account that waveform coding (time domain) methods assures a maximum level of intelligibility and naturalness of the synthesized speech, and that prosodic effects superimposing requires the alteration of pitch (frequency domain), we developed a hybrid time domain-LPC method, obtaining a better quality of the synthesized voice than those obtained with our former systems. This paper presents some theoretical considerations, signal processing and implementation aspects of this new synthesis method developed for the ROMVOX TTS system.
