VOCALOID 共鸣腔控制

Vocaloid Resonance Controls - Part 1

原作者:Joe Hogan

第一部分

In this brief article I will attempt to explain what the vocaloid resonance controls are, and give some pointers as to how they can be used. Please note that this is a small article, and will only scratch the surface of what is a massive subject. I hope this tutorial will point users in the right direction, and inspire them to experiment.

在这篇简短的文章中,我将解释什么是VOCALOID的“RESONANCE”共鸣腔,并给出一些如何使用它们的例子。但是请认识到这仅仅是一篇短文,我只能简单的描绘出共鸣腔这个复杂而庞大的控制参数的表象。我希望能借此文为广大使用者指出正确的研究和试验的方向。

什么是共鸣腔?

What is a resonance?

What they aren't: The Vocaloid resonance controls are NOT a parametric EQ or a filter!!
…. Well not in the conventional sense anyway, but you can get some crazy synth like filtering effects when using extreme settings.

首先指出它不是什么:VOCALOID的共鸣腔不是一个传统意义上的参量EQ控制或者一个过滤器,但是你可以用极端的参数设置去得到类似过滤器一样的效果。

这文章我太喜欢了……处处都说到了我说不出的感受……我向别人传教的时候无法解释什么的是共鸣腔,解释了对方也很难以理解,于是我总是先从EQ的角度出发,然后对他们说,这是一个和EQ类似的但是算法和效果完全不一样的参数,可以用EQ去触类旁通,但是实际用法是不一样的,需要自己揣摩。从最开始接触的时候我也以为它是EQ来着,但是用完了发现效果完全不是一回事。于是请记住这货绝对不是后期里面用的那种参量EQ!!!!!!

What they are: Vocaloid singing happens by attempting to synthesise the resonances of the human voice. There are many resonances covering the whole vocal frequency range, these resonances are known as formants. Formants are crucial as they not only govern the timbre (gender, richnes etc) of the voice but also the pronunciation of the vowels. During synthesis, Vocaloid is shifting the resonances around, effectively morphing the sounds into each other.

共鸣腔是:VOCALOID的歌声是模拟人类共鸣腔的结果。人声波段由许多共鸣腔构成,这些共鸣腔表现为共振峰。共振峰至关重要,因为它们不仅仅影响声音的音色(例如性别和饱满度等)还影响元音的发音。VOCALOID是通过调整声音的共鸣腔来有效的合成歌声。

For example the phoneme 'aI' (sounds like 'eye') starts with the sound 'uh' and then changes to 'ee', with a slight 'y' sound. During synthesis each of the resonances will move producing the required sound.

举个例子:音素“ai”(发音类似英文eye 中文“爱”)由“uh”开始,然后变换到“ee”最后用一个较轻的“y”结束。在发声的过程中,每个共鸣腔都将会提供需要的声音部分。如下图:

The 4 resonance controls in the vocaloid editor modify the values of the first 4 formants (0-3 in the graph). They are the lowest in frequency and they are the most important as they are not only the loudest, but they also dictate the percieved shape of the mouth and how a vowel is pronounced.

VOCALOID里面的4个共鸣腔参数对应控制如图的0到3区间里的共鸣腔声音。这四个频段的
共鸣腔是最重要的,因为它们不仅仅是声音中最重要和最响的部分,还决定了口型和元音的
发音。

Each of the 4 resonances has 3 controls… amplitude (volume), frequency (pitch) and band width (Q),each of these ranges from 0-127 with 64 being the default.

每一个共鸣腔参数由三个部分构成:
amplitude 对应部分的共鸣腔音量大小
frequency 对应部分的共鸣腔的震动频率。

(原文用了pitch来表述frequency的作用 Pitch是一种音高定义:用一秒钟的振动数来表示。频率次数多者音高,频率次数少者音低。将每秒振动440次的声音定为“a”,是目前国际通用的标准音。)

band width 对应部分共鸣腔的影响波段宽度。
每个参数范围从0到127,64是默认值。

It is important to note that the resonance controls are relative….. So, the changes you make to theresonance tracks are affecting the synthesis that is already taking place.

还有重要的一点是共鸣腔的参数控制是相对的,也就是说你对参数的改变是相对已经存在的合成声音的改变。

For example if a resonance frequency control is set to 64 you will get no change in sound.And if you increase the frequency of the resonance, you are increasing the frequency of that formant above where vocaloid would normally be synthesising it. The same principle applies to both Amplitude and bandwidth as well. This is why the controls are measured in a relative manner, and NOT in specific values like dB and hz.

举个例子:如果一个frequency的参数设置为64,你会发现合成的声音没有变化。如果你升高这个共鸣腔的frequency参数,VOCALOID在合成的时候就会增加了这个频段的震动频率,然后就能听到合成声音变化了。Amplitude和bandwidth也一样是相对参数。这就是为什么这些参数控制给出的数值都是0到127的相对值,而不是一个精确到HZ或者DB的绝对值。

怎么用?

So What are they for?

One of the main uses for the resonance controls is to change the pronunciation of the vowels. You canchange one vowel into another if you want, or you can make hybrid vowels that are in between 2 normal vowels. Its a tricky technique, but you can even use this to change the dialect of vocaloid.

经常用到的一种共鸣腔控制是改变元音发音。你可以把一个元音发音改变成另一个,或者做出介于两个元音发音之间的元音。这是个复杂的技巧,但是通过改变共鸣腔你甚至可以改变一个VOCALOID的口音。

You can also use resonances to thin or thicken up both vowel or voiced consonant. But as the resonances do not affect the noise component of the synthesis, they will not affect unvoiced onsonants in any way.

你也可用通过修改共鸣腔削薄或者加厚辅音和元音。但是共鸣腔不影响无声的气息部分,它只对有发声部分产生作用。
