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 harmonic plus noise model (HNM) is widely used for the modeling of audio signals. In this paper, we introduce perceptual frequency masking to the 2-band HNM, developed by Stylianou et al., applied to speech signals. An auditory model is used to recognize inaudible sinusoids, which will be removed from the set of model's parameters in order to reduce the(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)
