Simple representation of signal phase for harmonic speech models

A novel representation of the phase information in harmonic speech models is proposed. A transformation from instantaneous phases to initial phase shift differences with respect to the fundamental frequency provides a clear insight into the structure of the phase information and largely simplifies the manipulation of this information.
