Here is my first shot at a speech formant synthesizer. It only does the vowels for now because I couldn't yet figure out how to extract the envelopes needed for consonants from my recordings. Also I don't know if just a simple envelope will be enough for them. Any pointers to speech synthesis online resources on the subject will be greatly appreciated.

Formants are completely customizable on text files, so it should be straightforward to adapt it for another language.

All comments (even flame :P) welcome.

Hello,

I'm trying to make something that sounds like C64 SID chip. One particular property of that chip is that, it is possible to hard-sync two oscillators, so that the slave oscillators phase is reset to zero every time master oscillators phase returns to zero. I couldn't find a a way to implement this in pd.

Trying to capture the zero crossings on the master oscillator seems to be a dead end, because i'll have to turn it into a control signal somewhere to connect it to the phase input on slave phasor. And control signals are much too slow to catch every zero crossing.

Any ideas?

Thank you! I'm not too happy with the "u" vowel but the others sound quite clear to me too.
I am also trying to get the consonants by filtering a noise source with filters using vline~ envelopes. I was able to analyse the formant frequencies using a free software called sonic visualizer, but I couldn't quite grasp how to analyze the consonants with it. There are quite good tutorial on the web for formant synthesis, but I couldn't find anything about consonant synthesis. So i'm playing with prosody right now until I find a good resource.

That was really good. I liked it a lot.

Very clever indeed. Thank you very much!
