Abstract

We found the sinusoidal coding and harmonic plus noise modeling techniques very promising in our goal of reaching high quality of synthesized speech and simultaneously having possibility to compress well the speech unit database. We found this method to be quite sensitive to accurate determination of the pitch-frequency and the placement of the phonetic unit boundaries. It is also advantageous to ensure the coherence of phase components during synthesis stage that is not generally easy task. In our experiments, we observed that the phase coherence is more important (from the view of naturalness) then the necessity of the strict usage of the original phase component in all instants (frames). So, in our new experimental synthesis system we prefer keeping the phases coherent rather than trying to interpolate them. We reached very promising results.
