In a voiced utterance, the opening and closing of the glottis produces a pressure wave. This is referred to as the voice source. Then this pressure wave goes through the vocal tract and mouth. The voice source appears, in the time-domain, as a sequence of pulses. Looking at the spectrum of just a single pulse, […]
Wide-Band Voice Pulse Modeling[1] (also referred to as Wide-Band Harmonic Sinusoidal Modeling[2][5], presumably because it is also applicable to other monophonic harmonic sounds) is a hybrid time-frequency audio processing technique that models each time-domain period of the fundamental frequency in the frequency domain. This is done by calculating the times of minimally-phased impulses (in the…
NOTE: I have edited out parts from this old post that were wrong and based on misunderstandings I had at the time. This is quite outdated anyway though. In the last post about my vocal synthesis project, I talked about implementing the Wide-Band Voice Pulse Modeling algorithm. Since then, I’ve actually done some original research […]
NOTICE: Please don’t read this post! I had no idea what I was doing at the time, so a large amount of it is wrong. I will release a post when the project that spawned from this is finished. That post will have everything this post did, and a lot, lot more, but will way […]
