``Pink Trombone'' that can simulate the movement of ``inside the mouth'' when humans speak
When speaking, humans can dexterously use their tongue, throat, nose, etc. to make arbitrary sounds. However, most of these vocalizations are done unconsciously, and there are probably few people who are aware of how they move their tongue and throat when they are vocalizing. ' Pink Trombone ' is a simulator that allows you to check what kind of sounds are actually produced by manipulating the inside of your mouth on your browser.

When you access it, a cross-sectional view of the inside of your mouth will be displayed as shown below, and at the same time you will hear the voice 'Ah'. In the cross-sectional view, the 'lip' on the right side is the lip, the upper 'nasal cavity' is the nasal cavity, and the lower 'oral cavity' is the oral cavity. However, gums and teeth are not provided.
Click 'always voice' at the bottom right to turn always voice on or off. Also, by clicking 'pitch wobble', you can switch on/off the fluctuation that rides on the pitch of the voice being played. The bottom 'voicebox control' changes the pitch by moving the rectangular slider left and right, and the volume by moving it up and down.
The model inside the mouth will be transformed by dragging it. For example, 'tongue control' can change the movement of the tongue. You can see that by changing the position of the tongue:
Between the nasal cavity and the oral cavity is the palate, which is the 'soft palate' at the back (left) and the 'hard palate' at the front (right). If you click just between the soft palate and the hard palate and create a slight gap with your tongue, you will see that the fricative sound that is the consonant of s, such as 'shi', is reproduced.
Click your lips to close them and stop speaking. If you open your lips vigorously in this state, the p consonant will be reproduced.
Click on the hard palate and the tip of your tongue will touch it. By briefly touching the tongue to the hard palate, the consonant sound n or r can be reproduced.
The voice stops when you tighten the glottis at the back of your throat. If you open it a little, the h consonant 'ha' will be played.
You can see how Pink Trombone actually simulates how to make voices by watching the movie below.

According to Neil Turpen, the developer of Pink Trombone and a researcher at the Institute of Mathematics of the Academy of Sciences of the Czech Republic, the development was triggered by his daughter starting to speak. 'Pink Trombone is an interactive articulatory speech synthesizer that creates speech by simply modeling the physical shape and movement of the human vocal tract,' Turpen told the IT news site Digital Trends . Programs have existed in the past, but the interfaces tended to be unfriendly, so I decided to create something that was fun to use.'
