The partly preserved natural phases in the concatenative speech synthesis based on the harmonic/noise approach

Original language description

This paper describes our advances in the development of the Czech TTS system achieved mainly in the field of speech signal generation. We found the approaches for speech representation based on sinusoidal coding [1] or harmonic plus noise modeling [2] respectively very promising for our goal. It is mainly due to high compression possibility of the spectral representation of the speech. The major inconvenience is the necessity of natural phase components to reach quality naturally sounding synthesis. Since there is no known method for suitable phase representation, the methods for its substitution must be searched. In our experiments, we observed the phase coherence to be more important (from the view of naturalness) then the necessity of the strict usage of the original phase component in all instants (frames). We proceed from this experience and here we propose our method where only the one phase vector is needed for each voiced segment (continuous sequence of voiced frames) in ever
