JMT's progress in enhancing Vocaloid

Hello guys!

It seems we have some progress in adding of Expression elements into Vocaloid singing, using our PM technology. For “Internet Angel” (our 2nd example) we used special PMStyle (Onyx Arranger 2.1), which has calculated Velocity, Pitch Wheel, Noise, Gender Factor, Harmonics, Brightness curves automatically. No manual editing at all! You can find more details at JMT site:

Hi Alexei

Cool. :)

On this song it is much easier to hear the words. Great progress. I did not had to read the lyrics to understand the meaning.

The vibrato sounds a bit like an old woman, though. Elderly ladies have a tendency to have a wide and “uncontrolled vibrato feel”. ;) Perhaps the vibrato could be less expressive and more main stream in the algoritm?

Leon still sounds a bit nasal. Can this be corrected with more brightness?

Thanks Bob!
Sorry for not taking part in the forum before, I’m always so busy :-)
However, I’m sure a bit later we will be able to provide Vocaloid users with some helpful advice, I even think we can create short Vocaloid FAQ section on JMT and NTONYX sites based on users questions and our experiments.
Yes, in Angel all words sound clearer, and it is achieved partly with the using of Noise increasing in the beginning and ending of phrase, I plan to use something similar for the word clearing in the future.
Regarding vibato: Oh, it is not a problem to make ANY rate, depth, and fluctuation… its simply not the priority now.
The most improtant is that all curves are calculated by automat in a second, and we can change them as we want. However, we do all this in Onyx, but to make it more comfortable for users, it must be a functionality of Vocaloid itself.

I agree that the vibrato on the Internet Angel demo is too “over the top”. I would disagree about intelligibility of the words though. I still needed to read the text to understand them. (Maybe it’s me – I am getting old!). If you [b:267y9y65]really [/b:267y9y65]want to help the Vocaloid community some more, perhaps you could explain precisely how to use the [b:267y9y65]resonance[/b:267y9y65] parameters. They clearly relate to various voice formant frequency bands but there is no literature that tells what these frequencies are. The parameters in the Vocaloid editor are the usual 0 – 127 or whatever and give no information as to what frequency it is you are changing, why, and by how much. Can these be controlled by your software?
Thanks
Chris

regarding resonances…. I have written half a tutorial on it, a month or so ago. Unfortunately I had to put it on the back burner….. (grrrr… life is far too busy!) I will try and finish it as soon as I can. <img class=” />

(Please note: the resonance thing is a massive subject that a tutorial will only scratch the surface of.)

I’m sure I speak for most people when I say that any information will be eagerly and gratefully received, Joe. I’ve just downloaded your phoneme chart and will be pouring over it real soon – many thanks! On the JMT thing, there would appear to be a case where Yamaha might consider opening up the (MIDI) editor by implementing some fancy (realtime?) version of the kind found for example in Steinberg’s MIDI plug in system, where processing/creation of events can be inserted into the data stream through modular third party plug ins. Given that Steinberg and Yamaha have recently announced a joint studio venture and the raw speed of Yamaha’s Firewire/mLan technology maybe they could open up the vocaloid engine this way?

I would dearly love to have a real-time method of tweaking the vocal parameters of Vocaloid. Where I could hear the result of changing the resonance, for example, as the voice sounded. (Just like on a real synth). (Just like Brother Gregory in Cubase – as I suggested in another thread)

I could be wrong – BUT – I believe that Yamaha are saying that they have fixed the VST plugin and that’s what the coming update will bring i.e. the ability to tweak the resonance on the fly within Cubase or other VST complient host. Is this a correct assumption?

Did anybody recognize that “melizmas”, NTONYX talking about? They are pretty delicate. Trying to understand how they did this, I removed “harmonics-controller” from “Internet Angel” MIDI file and heard rough pitch glidings in the resulting wav.
Seems, synchronized harmonics curve soles to smooth pitch changes.

This melizmas make the vocal more like real soul vocal!

When I lower or raise harmonics, it greatly affects the volume. I fact I used harmonics to fade out on a track that velocity wouldn’t fade enough.
