Direct Synthesis – continued

Looking at the FFT of a vowel, you can see that each formant has it’s own frequency and amplitude. These show up as “blobs” – some stretching for the duration of the wave, others for only a portion: For example, … Continue reading

Direct Synthesis

One of the problems that I’ve been encountering with the use of digital filters is a “squeal” when parameters rapidly change. Dennis Klatt published a solution for this which recalculated the stored filter coefficients, but I’ve never been able to … Continue reading

Working with Plosives

After a number of iterations I’ve finally got something that works for plosives. Similar to early version of Klaat, I can trigger a  white noise “burst” of fixed duration (about 5ms) that’s sent down the frication branch. One of the … Continue reading

Working on Phonemes

I’m slowly working my way through the set of consonants. Most of the consonants fall into one of four general types: Stop Consonant /b, ch, d, g, j, k, p, t/ Fricative /dh, f, s, sh, v, z, zh/ Nasal … Continue reading

Consonants

After having limited success with vocal tract modeling, I decided to take a step backwards and focus on formant synthesis. Since synSinger could already make fairly good vowels, I figured I should focus on finally synthesizing decent consonants. Rather than … Continue reading
