Abstract

The paper proposes our innovative approach to speech signal representation and generation in the harmonic/noise based speech synthesis. It is aimed to the high-quality synthesis on the low resource devices. The other implementations with artificial phases (linear, minimal, zeroed, etc.) produce the synthesized speech with unsatisfactory quality. In proposed approach we use phase data derived from real speech signals to reach natural sounding synthesis. We choose, so-called, representative phase vectors, that are only stored to the speech unit database. We reached a dramatic reduction of demands for the database storage space. It corresponds with the rate (number of voiced speech units):(number of voiced speech frames) stored in the database. Our proposed method also ensures the phase coherence in t he synthesized speech signal automatically.
