Claim 1:
2. A method of generating a synthetic voice, comprising the steps of:
a. capturing a set of speech segments;
b. identifying phonemes within each speech segment using a phoneme processor, then clipping each speech segment to isolate the separate phonemes within each speech segment, thereby forming phoneme segments, and then grouping the phoneme segments such that each group of phoneme segments have a common phoneme type;
c. identifying pitch types within each group of phoneme segments using a pitch processor, and then grouping the phoneme segments such that each phoneme segment within a group of phoneme segments has a common phoneme-pitch type, thereby forming phoneme-pitch groups;
d. converting the phoneme segments into a first set of spectral segments using a Mel-Spectrogram;
e. performing SPL analysis on each spectral segment in the first set of spectral segments to generate a first set of SPL tracks, with each SPL track of the first set of SPL tracks corresponding to a given spectral segment and identifying sound pressure, tone, and pause attributes of the given spectral segment;
f. grouping the first set of spectral segments such that every spectral segment within a group of spectral segments has common sound attributes;
g. inputting the first set of spectral segments and the first set of SPL tracks into a first neural vocoder;
h. comparing sound attributes of the first set of spectral segments to standard sound attribute ranges, with the standard sound attribute ranges selected for comparison determined by the phoneme-pitch group and the SPL tracks;
i. culling spectral segments with attributes that fall outside standard attribute ranges from the first set of spectral segments;
j. merging remaining spectral segments within each group of common phoneme-pitch type into a merged segment, with the merged segments being a second set of spectral segments.
