Segmental Duration Control Based on an Articulatory Model

A pulse-repetition-period and analyzer comprising binary converter means for converting an input waveform into a series of equal-amplitude binary pulses, shift register means for sorting the pulses into a series of pulse trains ordered according to their pulse repetition periods, shift register means for rejecting from each pulse train any pulses constituting a harmonic rather than a fundamental signal at the input weighted integrator means for individually integrating said fundamental pulse trains and, scanning means for sampling the integrator means outputs in time sequence.
