Reducing audible spectral discontinuities
In this paper, a common problem in diphone synthesis is discussed, viz., the occurrence of audible discontinuities at diphone boundaries. Informal observations show that spectral mismatch is most likely the cause of this phenomenon. We first set out to find an objective spectral measure for discontinuity. To this end, several spectral distance measures are related to the results of a listening ...

متن کاملObjective distance measures for spectral discontinuities in concatenative speech synthesis
The quality of unit selection based concatenative speech synthesis mainly depends on how well two successive units can be joined together to minimise the audible discontinuities. The objective measure of discontinuity used when selecting units is known as the join cost. The ideal join cost will measure perceived discontinuity, based on easily measurable spectral properties of the units being jo...
متن کاملTracking discontinuities in hyperbolic conservation laws with spectral accuracy
It is well known that the spectral solutions of conservation laws have the attractive distinguishing property of infiniteorder convergence (also called spectral accuracy) when they are smooth (e.g., [C. Canuto, M.Y. Hussaini, A. Quarteroni, T.A. Zang, Spectral Methods for Fluid Dynamics, Springer-Verlag, Heidelberg, 1988; J.P. Boyd, Chebyshev and Fourier Spectral Methods, second ed., Dover, New...
متن کاملReducing the Spectral Index in Supernatural Inflation
Supernatural inflation is an attractive model based just on a flat direction with soft SUSY breaking mass terms in the framework of supersymmetry. The beauty of the model is inferred from its name that the model needs no fine-tuning. However, the prediction of the spectral index is ns > ∼ 1, in contrast to experimental data. In this paper, we show that the beauty of supernatural inflation with ...
