Abstract
A simple model for generating aperiodic components in synthetic speech is introduced by modifying lower frequency representation for improving voice quality of resynthesized or morphed speech. The new representation is simple enough to arrow intuitive manipulation of this quality relating attribute. The model represents aperiodic component using a sigmoidal function and employs frequency axis warping in the lower frequency region. It also introduced temporal envelope shapers for aperiodic components.
