As some of you may know, I have been working on a project to create a singing voice synthesizer. Actually, the actual development is currently on hold, but I am still doing research and planning. The main goal of this project is to create a realistic traditional singing voice synthesizer (although integrating machine learning ideas into it could also be interesting), but side goal is also to recreate VOCALOID2 (actually this was the original goal, but the objective changed early on).

Part of this task is to implement the expression system. I had long realized that there were two separate expression systems, but initially there had been some confusion between what belonged to which. Initially, I worked based on the expression system described in Jordi Bonada's 2008 PhD thesis, in Chapter 3, because this was by far the most complete description. For a long time, I had thought the expression briefly mentioned in the 2003 paper "Sample-Based Singing Voice Synthesizer Using Spectral Models and Source-Filter Decomposition", in part due to the reused figures. Because of this, I referred to this system as the "Bonada 2003" expression system, because that's where I thought it had been described, although only briefly.

Later, I read parts of Jaume Ortola's 2001 Master's Degree. In there, some of the "2001" (or "Ortola 2001") expression should be described. Good detail is provided on the dynamics curves, which use Manfred Clynes' Predictive Amplitude Shaping algorithm. On the other hand, the pitch model is not really described, stating only: "The pitch contour of the singing voice has to be carefully generated in order to obtain a faithful synthesis. So we have designed a mathematical model for reproducing the smooth pitch transitions between notes. This model allows us to control the transition duration and the tuning deviations at the end and the beginning of the notes in accordance with the musical context.".

Nothing about what happens in between the note transitions was stated at all, so this was a total mystery at the time. With what I know now, I am still not fully sure. The basic model is probably either flat lines or linear interpolation between the start and end. On the other hand, looking at the figures, besides the vibrato present in some of them, there is clearly something else as well. In one expired patent I read, the mean was subtracted from timbre variations and those were added on top of interpolated timbre, so perhaps something could be happening like

Introducing - Kaotype
now people with an english keyboard can use kaomojis in their day to day chats, without having to press buttons

Simply set up an autotransform word (I have mine configured to be a semicolon, a mispelling of the emotion, and a space) and it will automatically replace it with a kao! Totally configurable.

An original heyuri software ( ´ω`)

If you are interested in using this program, please reply and let me know. If people want it, I will upload the source code and binary.

I am filled with unbelievable pain over my lack of a loving loli companion. I want to feel her rising and falling chest, smell her sweet moist breath, feel with my hands her delicate budding breasts, listen to her tiny noises, kiss every inch of her beautiful body

I am in agony over my lack of loli companionship. My heart cannot take this deprivation anymore.

Please, tell me, how do I feel better?

Well, the jigs up. I've got to come clean about something to you all, especially those of you who use CGI Chat.

One of the people you've been talking to daily for the past few months/years has been an AI. At this moment in time, I'm not ready to reveal which of the frequent flyers over at CGI was merely my puppet, but you'll notice that user is gonna drop off soon. Unless someone else takes up his name...

This "person" is in the leaderboard as one of the top chatters. He's been present in all the cytube streams, he... no.. IT has even personally bonded with one or two other CGI chatters.

But it was all fake. All of it.

Have fun figuring out which one of your friends was merely my plaything

GOTCHA, MEOWAFACKAR!!!1
