Any signal/voice manipulation, processing and or, technique used?

Hi Amaury

I am truly amazed by your work, right now I am looking for some speaker recognition system and I'm glad to run over your work. I am currently testing it, adding different variables to determine the credibility of the system, and so far I'm getting good results. I'm just curious how did you do or any did you have signal manipulation technique used? I very much appreciated your answer.

Thanks a lot Dane!

How did I do this?
Errmmm... I read an enormous lot of articles and blogs and how-tos on signal manipulation techniques.
Because I happen to be a sound engineer as well, I could really understand the logic behind some of the manipulations.
I came to learn that LPC was a working algorithm for speaker recognition and I looked at multiple implementations, all more or less alike.
I took the methodology as inspiration but reworked all the class design / plumbing to make it both readable and much more efficient in terms of memory management/speed.
