[Paid Version] Text-to-Speech Commercial Licenses & YouTube Use Guide

When people aiming to become YouTubers decide to use "text-to-speech software," their biggest concern is about commercial use.

Using "text-to-speech software" on YouTube with the expectation of advertising revenue or affiliate income constitutes legitimate commercial use.

This time, we will introduce four paid text-to-speech software options, covering whether commercial use is possible and what the licensing entails.

If you accidentally violate the terms of service by using text-to-speech software that does not allow commercial use:

• Your videos might be deleted, or your account might be suspended,
• You might receive complaints from the text-to-speech software company,

Various risks such as these can be expected.

It is important to check the terms of use before purchasing to avoid breaking the rules.

However, there are many text-to-speech software options in the world.

When comparing multiple software options:

• Which ones are OK for commercial use,
• Which ones are not,
• Which ones do not require a license purchase for individual use on YouTube,

It is difficult to organize because there are so many differences.

Please use this article as a reference for choosing text-to-speech software that is OK for commercial use.

1. Ondoku
2. AI Talk

5. Yukkuri-style voice (AquesTalk2)

Since there are many, we will pick up and briefly explain product introductions and commercial use, especially when used by individuals on YouTube.

Ondoku (Free use is also OK)

The first one is the AI text-to-speech software, 『Ondoku』.

The price ranges from free to 3,278 yen (tax included).

『Ondoku』 allows free use and downloads without registration.

Registering increases the number of characters you can read for free.

It supports reading in Japanese as well as multiple languages.

Paid members can use between 200,000 and 1,000,000 characters per month.

AI Talk

The second one is AI Talk.

Developed by AI Inc., it is a well-known and famous text-to-speech software.

The price starts from 16,500 yen.

In "Kantan AI Talk 3," the following are available:

• 4 female voices
• 1 male voice
• 1 Kansai dialect female voice
• 1 Kansai dialect male voice

It also supports emotional expression, and you can experience the speech synthesis on their website.

Regarding commercial use, the website states that "basically, commercial or business use is not possible."

However, looking closer, it says "use for narration of web video works (YouTube, etc.) on video sharing sites is OK."

Basically, for individuals, it seems that a standard license can be used for things that earn advertising revenue from YouTube views.

However, using it for video creation commissioned as a paid job, or for YouTube videos that have sponsors and receive rewards, is considered commercial. It cannot be used within the scope of a standard license.

Note that AI Talk does not sell commercial licenses for individuals. For commercial use by corporations, there are separate products for corporations.

VOICEROID

The third one is VOICEROID.

This software uses a speech synthesis engine provided by AI Inc. and is sold by AHS, Gynoid (Yoshimoto), Yamaha, and Internet.

The price starts from 15,180 yen.

This text-to-speech software features a lineup of over 20 character voices, many of which are based on the voices of voice actors, giving the sounds high originality.

Every voice fits the illustration image of the cute character perfectly.

However, because the providing companies differ depending on the sound source, the terms of use vary slightly for each software.

The scope of permitted commercial use also differs, so careful attention is required.

• Basically possible for individual use.
• Commercial use requires checking the terms of use for each (due to different providers).
• There is different pricing for corporations.

*If you want to read with VOICEROID characters, "A.I.VOICE" and "A.I.VOICE2" are recommended.

as the three characters.

Regarding the commercial use of interest, specifically use in video postings such as on YouTube:

It states:

"It can be used for free for video postings, or when individuals or doujin circles post to earn advertising revenue."

Acts such as individuals posting videos to YouTube can be done without purchasing a commercial license.

However, in that case, it is necessary to state the CeVIO character name and that it is CeVIO in the video description field or similar.

Note that for video creation undertaken for a fee, a paid commercial use license is required. The license fee requires an estimate. No specific amount was stated.
