In this paper, we present an extension of a novel continuous residual-based vocoder for statistical parametric speech synthesis. Previous work has shown the advantages of adding envelope modulated noise to the voiced excitation, but this has not been investigated yet in the context of continuous vocoders, i.e. of which all parameters are continuous. The noise component is often not accurately m...

SUMMARY Wave trains in high-frequency seismograms of local earthquakes are mostly composed of incoherent waves that are scattered by distributed heterogeneities. Their waveforms are very complex and significantly different from those computed for conventional layered structures; however, their envelopes are repeatable, frequency dependent, and vary regionally. Well-logs obtained from deep boreh...

Abstract A simple geometric mechanism: ‘the locus of intersections perpendicular bisectors and normal lines’, often arises in many guises nonlinear sciences. In this paper, a new application mechanism is given. Namely, we show that gives answers to all four basic problems on envelopes created by hyperplane families (existence problem, representation equivalence problem definitions, uniqueness p...
