## History

On June 26, 2020, Kotonoha Akane & Aoi were announced to receive a shared singing library for Synthesizer V Studio. In a press release held by AH-Software Co. Ltd. on the same day, their package was unveiled alongside Saki and the Synthesizer V Studio Pro editor. They were scheduled to release on July 30. A special promotional campaign was held on AH-Software's online store until the end of September which offered up to half the price to those who own previous AH-Software products. Pre-orders for the Kotonoha package also began on June 26.

Trial versions of the Kotonohas were released for the online Web Synthesizer V engine on July 22. The full version of the Kotonohas released on July 30 as expected. They also received a "Lite" version of their voice database on September 24. As of December 1, 2021, the Web version of the Kotonohas became non-functional as error messages were returned in spite of meeting minimum Chrome/Edge version requirements.

**Package details** as noted:

Kotonoha Akane and Aoi are a pair of vocalists sharing a single young female voice database. Different parameters in the program are used to produce two different sounding voices. AH-Software noted that the voice database can be soft, yet strong, and can handle a variety of songs, supporting a wide range of genres.
**Phonetic notes** as noted:

Phoneme format: Romaji
**Software issues** as noted:

* Because the pair is using a single voice database instead of two distinct ones per character (for their VOICEROID and A.I. VOICE products, they have two separate speech voicebanks with distinguishable accents), it is nearly impossible to tell who is singing a song without a producer explicitly stating the name.
	+ In addition to this, producers may interpret Akane and Aoi's voices differently to others' preferences.
* As the Lite voice databases are generally restricted to monopitch (one pitch) only, the Kotonohas' range is noted to be Cs4 in this version.

**System requirements** as noted:

**Hardware Requirements:**

* CPU: Intel Core i3 or higher
* RAM: 2GB or higher
* Disk Space: 1 GB or higher (for installing one voice database)
	+ The amount of space required depends on the number of voice databases installed.
* Display: 1280 x 800 or higher
