Abstract
A speech vocoder device and corresponding method synthesizes speech excitation waveforms. The method entails reconstructing (216) an excitation target from decoded speech data, creating (220) aligned excitation segments by normalizing (296), correlating (298), and aligning (300) a source segment and a target segment, reconstructing normalized intervening segments by ensemble interpolating (318) between the source segment and the target segment, denormalizing (320) the normalized intervening segments, and reconstructing (322) an excitation waveform from the denormalized intervening segments, the source segment, and the target segment.
