About three weeks ago, I promised that the following day, I would make a post the following day about a big update. I didn't say what it was about at the time, but it was going to be about the Excitation plus Resonance model. Unfortunately, I was not able to make the post at the time, and am sorry for that. However, I do have a significant update now.

Back in April, I began to implement the Excitation plus Resonance model. The Excitation plus Resonance is model of the voice timbre spectrum. It consists of several parts actually, but the two main ones in terms of implementation difficult are the source curve and vocal tract resonances.

The source curves approximates the frequency-domain response of the voice source, and the resonances correspond roughly to formants and are model using a modified version of the Klatt Formant. The problem lies not in implementing this model - it is actually very easy to do so - but rather estimating the parameters for this model, which is not given in any of the papers I've read. Back in April, I spent a couple days trying to create it. Ultimately, I came up with something that was quite poor quality, very slow, and required very specific parameters but accepted it. Much later though, I found that the exact method to estimate the source curve is actually given in the expired EpR patent.

Not wanting to repeat my previous mistake, when I began to work on EpR, I searched extensively for the method used to estimate the resonances, but came up with nothing. Eventually, I began to trying figure it out myself. I started by recreating the data in the paper by annotating an image extracted from the paper in Photoshop and then running a python script on said annotated images. I would then compared the result of my approach on said recreated data to the paper's.

I actually had been thinking about it long before my first attempt. I already had a method that I had conceived of. The main idea of this method was that the reciprocal of the second derivative could be used to approximate the bandwidths of the resonances.

Initially, after having to make a few adaptions to the approach after realizing several things wouldn't work quite how I thought, the results vastly outperformed my initial expectations. There were several ideas that didn't work out, but overall I felt good at the end of the first day. I debated whether to continue trying or to just go with what I had. I decided that would go with what I had and make a post about it the following d

why is 4chan so boring to browse?

I wish to be licked by my "heisei" goth friend like this... We look like that too

ｷﾀ━━━(ﾟ∀ﾟ)━━━!!

Happy birthday, Heyuri-chan! Ur 7 years old now, and as cute as ever

Let's celebrate!

anyone know what happened to lolicore.net?
i can see its dead on wayback machine but any more lore?

ｷﾀ━━━(ﾟ∀ﾟ)━━━!!

Your present

I would like to congratulate Heyuri on 7 years of non-total annihilation. Omedeto

[scroll]As a tween before I discovered GuP(it was just going to be launched tbh) I had a fantasy, or LARP, call what you want, as a sort of aristocratic androgyne sukeban that altered between a trad tomboy like Kino and a mixed styles lolita... I can buy a Miata and a retro motorcycle if I can find it and maybe kiss a girl friend, but I will never have that experience where I am the unique nerdy, aristocratic origin(i'm technically H. Rawicz but don't mind it so much.) knightsmaid turned into a road bandit delinquent with her other delinquent friends, I will never be the perfect genderbenter, I am not a magical girl even if I might be a practitioner, and I am not tongue kissing shota with my friend circles that all love him as if he was a cigar being passed(I don't even smoke because i'm sensitive! LOL), I'm never dropping sake all over my body and waiting for shota to drink, I am not a sukegopnik, I am beyond chuuni and beyond mokkochi... But at least I have a shota-sized dirty pillow and love otaku activities(´～`)
