Innovative Technology for Natural, Human-Like Singing

Synthesizer V Studio is singing voice synthesis software developed by Dreamtonics Co., Ltd., and it excels at generating natural, smooth singing.
Furthermore, "Synthesizer V AI," the next-generation voice synthesis engine, uses AI (artificial intelligence) technology, and Hibiki Koto is a voice database built with this technology.
As a result, it can generate more human-like and expressive singing.

Vocal Styles for a Wide Range of Genres

In addition to the default, Hibiki Koto comes with six vocal styles, Ballade, Cute, Dark, Falsetto, Musical and Power, so you can choose the best style for the mood of the song and the emotion you want to express.

We had her sing existing songs using these styles.

As you can hear, we think you can sense Hibiki Koto's rich variety of styles and the high expressiveness and appeal of each one.
Details of each style are below.

"Ballade": A Gentle, Lustrous Voice

• Aimer: Sign

Compared with the default style, it is a gentle, soft way of singing.
The Ballade style is ideal when you want to express a delicate fragility or melancholy.

• Ballads
• Acoustic songs
• Scenes where you want to create a moving moment

These are some situations where it looks effective.
Its lustrous, emotional tone suggests that even singing voice synthesis software can resonate poignantly with listeners.

• YOASOBI: Butai ni Tatte

The impression changes completely, as if a different character were singing!
Compared with the default style, it is an innocent, sweet way of singing.
The Cute style is ideal when you want to express cuteness.

• Poppy idol songs
• Character songs
• Songs with a fanciful mood

It looks likely to shine in songs like these.
This time we used an upbeat, light song, but it is a style we would like to try with songs of other flavors too.

"Dark": A Cool, Tight Voice

• Yorushika: Aporia

It has a maturity different from the default style, with a cool yet deep way of singing.
The Dark style is ideal when you want to express a cool, calm mood.

It looks able to create a striking expression in songs like these.
It has fewer ups and downs than the other styles, which is also nice because it can be used flexibly depending on the purpose!

"Falsetto": A Delicate, Airy Voice

The high range is sung in an airy, soft way.
It gives the impression of a style specialized for falsetto (head voice).

• Ballads that make use of the high range
• Songs where falsetto shines
• Long tones and choruses in the high range

It looks capable of delicate expression in cases like these.
Using parameters such as Breath and Tone Shift lets you bring out the characteristics of falsetto even more effectively.

It is a full-bodied way of singing characterized by dynamic inflection.
The Musical style is ideal when you want dramatic expression like a musical.

• Musical-style songs

It looks likely to further enhance the world of songs like these.
Reon Tachibana, who provided the original voice, is active as a musical singer, and we felt this style brings out Hibiki Koto's individuality as a one-of-a-kind vocal style.

"Power": An Energetic, Emotional Voice

• Ringo Sheena: Tsumi to Batsu

It is a powerful, strong way of singing, with plenty of volume and expansiveness.
The Power style is ideal when you want to express strength or intensity.

Even in songs like these, which test a vocalist's ability, it looks able to show a convincing presence.
The energetic, cool voice gives songs a sense of drive, and we felt new possibilities for singing voice synthesis software.

"Dark + Cute": A Deep, Sweet Voice

Vocal styles can also be blended.
For example, if you mix Dark and Cute, you get yet another impression.

In this way, by combining vocal styles and adjusting parameters, you can generate a voice to your liking.
Beyond the base voice for the song, by adjusting it to suit the story or scene, you can create an expressive vocal.
