このページでは、声の響く空間、そして声質について説明していきます。

　　Vocalization

As is also the nature of sound, sound is vibration of air. And as the sound is being transmitted, the sound repeats reflections in space. Then, what is the space in which the voice resonates? I will explain the breath-hitting part with a little touch. The space in which the voice resonates is divided into three categories: "nasal cavity" "oral cavity" "throat cavity". Please see the figure below.

"Nasal cavity" is the space behind the nostrils. This sounds echoing real voice and mix voice. The nasal cavity echoes well when you have a cold, such as a sniff. When closing your mouth, making a sound of Japanese "M" or making humming, I think that the voice will come out beautifully if it is made to resonate mainly here.
Next, "oral cavity" is in the so-called mouth. When sounding out, it sounds most of the time, even though the proportion that sounds is different. Breathable positions in this mouth are roughly divided into two, "Hard Palette" and "Soft Palette". You can tell by touching the top of the mouth with your tongue, but close to the tooth is hard (this is a hard palette), and when you breathe neatly here, the real voice echoes very well. And behind it is soft (here is a soft palette), here we use it to echo the falsetto. There are so many breath-fighting positions when you divide it in detail, so if you try it yourself, there may be interesting discoveries!
And, although it is "throat cavity", as in the word "ENT", this is a throat space in a word. This is characterized by being thinner than the other two. This is because it makes me realize that when I give out a falsetto or a whistle voice I realize that it is clearly different from the real voice.
These spaces do not have a pretty limited range and are connected a little, so it is a little confusing, but I think that you can understand the approximate position if you actually try to speak!

　　Quality of Voice

I wrote it in the space, but please change the breathing position, breathing position, in the oral cavity. You should have a point where your voice will echo the first as you move gradually. This point also varies from person to person. Also, I think that it is fun to change the face angle when sounding a voice. The point which echoes 1 is said to be somewhere somewhere between about 30 ° upward from the point facing directly in general. Please try it!
