ABSTRACT:
The speech synthesizer minimizes storage requirements by storing basis functions each defining a waveform segment or phoneme within a pitch period and including formants F1 and F2, featuring readin at one rate and readout at different rates within the pitch period. The synthesizer is characterized by each basis function being represented by a data point plotted on a single line on a chart having first and second formant log-log axes and means for producing a speech waveform segment approximately representing any desired point located off of the single line on the chart by selecting and reading out of the memory one of the basis functions at a rate different than the basic storage rate.
