Whats the difference between HLsyn and SenSyn?
A. HLsyn is a “high-level” parametric synthesizer that produces more natural-sounding speech from fewer time-varying parameters (13) than SenSyn (48). HLsyn uses fewer parameters by exploiting the interdependence of the parameters and subjecting them to inter-parameter constraints. These 13 parameters are more easily interpreted in terms of articulation. HLsyn transforms the HL parameters into the lower (Klatt) level (or KL) parameters of SenSyn through complex mapping relations. Additionally, HLsyn’s user interface is much easier to use, and more user-friendly, than SenSyn’s.
