Commercial Use Narrator Series

The "Commercial Use Narrator Series" is a speech synthesis software targeting business and educational use.

As the name suggests, all voices are available for commercial use.

• VOICEPEAK Commercial Use 6 Narrator Set

These two types are available.

The base "VOICEPEAK Commercial Use 6 Narrator Set" includes 3 female voices, 3 male voices, and 1 girl's voice.

The additional voices in "VOICEPEAK Commercial Use Narrator" offer 3 female voices, 4 male voices, and 1 boy's voice.

Since no specific character illustrations are set for each voice, they are ideal for business use such as video narration or in-store announcements.

Character Series

The "Character Series" is speech synthesis software where attractive characters are set for each voice.

In addition to original characters from AHS Co., Ltd., characters from other speech synthesis software such as "VOICEROID", "CeVIO", and "Tohoku Project" have also been productized.

you can acquire a total of 3 voices at once: Main character + Bonus character + Firimomen.

Be Careful with Licenses When Using Commercially

A point of caution regarding the Character Series is that the licenses for commercial use differ greatly for each character.

Basically, commercial use becomes possible by purchasing:

• Individual commercial license
• Corporate license

However, some characters are not allowed for commercial use.

Additionally, while purchasing a commercial license is unnecessary if individuals or doujin circles distribute works for free or for a fee for non-profit purposes,

• Use in affiliate marketing
• Use as the voice of an original character

there are uses prohibited by the terms of use for specific characters only.

It is recommended to check the terms of use for the specific character in advance.
