The harmonic plus noise model (HNM) is widely used for spectral modeling of mixed harmonic/noise speech sounds. In this paper, we present an analysis/synthesis system based on a long-term two-band HNM. “Long-term” means that the time-trajectories of the HNM parameters are modeled using “smooth” (discrete cosine) functions depending on a small set of(More)
The measure of quality of service (QoS) is a priority for telecommunication companies, particularly the measure of speech quality. This measure is generally realized by objective quality rating models in GSM networks. In this paper, we address the dependence of such objective quality assessment algorithms on the language of the speech under test, especially(More)
