[Paid Version] Commercial Licenses for Text-to-Speech Software on YouTube

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 expectations of advertising or affiliate revenue is strictly considered commercial use.

This time, we will introduce whether commercial use is possible for four paid text-to-speech software programs and what their licenses are like.

If you accidentally use text-to-speech software that does not allow commercial use by breaking the terms,

• Videos may be deleted, or accounts may be suspended,
• Complaints may come from the text-to-speech software company,

and various other risks are anticipated.

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

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

When comparing multiple software programs,

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

there are many differences, making it difficult to organize.

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

[Commercial OK] Explaining Paid Text-to-Speech Software

This time, we will introduce:

1. Ondoku
2. AI Talk
3. VOICEROID
4. CeVIO
5. Yukkuri-type voices (AquesTalk2)

Since there are many, we will pick up and briefly explain product introductions and commercial use, especially for individual use 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 2,980 yen.

"Ondoku" allows free use and downloads without the need for membership registration.

Registering increases the number of characters that can be read aloud for free.

It supports reading aloud in Japanese, as well as multiple languages.

For paid members, 200,000 to 1,000,000 characters per month become available.

Even free members can use it for commercial purposes without any particular restrictions.

If you are looking for text-to-speech software, we recommend trying "Ondoku" first.

Why not experience the high-performance AI narration of "Ondoku"?

AI Talk

The second one is AI Talk.

A well-known text-to-speech software developed by AI Co., Ltd.

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 speech synthesis on their website.

Regarding commercial use, the website states, "Basically, commercial use and business use are not allowed."

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

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

However, using it for video creation commissioned as a paid job, or for YouTube videos that receive compensation from sponsors, etc., is considered commercial. These cannot be used within the scope of a standard license.

Furthermore, AI Talk does not sell commercial licenses. For corporate commercial use, there are separate products for corporations.

VOICEROID

The third one is VOICEROID.

This software features a speech synthesis engine provided by AI Co., Ltd., 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 sound sources based on voice actors, giving the voices high uniqueness.

Each voice perfectly matches the image of its cute character illustration.

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

The scope of available commercial use also varies, so caution is highly necessary.

• Basically possible for individual use.
• For commercial use, check each terms of use (as the providers differ).
• For corporations, there is a different pricing structure.

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

CeVIO

The fourth one is CeVIO.

There was a free version of CeVIO until November 19, 2014, but now only a 30-day trial version is available. The price starts from 6,600 yen.

In the CeVIO Creative Studio currently on sale as of 2021, there are:

• Sato Sasara,
• Suzuki Tsudumi,
• Takahashi,

You can purchase a set of the three or buy them individually.

Let's check the commercial use we're interested in, specifically regarding use in video postings such as on YouTube.

It states:

"For use in video postings, you can use it for free when posting as an individual or a doujin circle to earn advertising revenue."

For acts such as individuals posting videos to YouTube, it can be used without purchasing a commercial license.

However, in that case, you must state the CeVIO character name and that it is CeVIO in the video description field, etc.

Furthermore, for video creation commissioned for a fee, a paid commercial license is required. The license fee requires an estimate. There was no mention of the specific amount.

Yukkuri-type voices (Bouyomi-chan, AquesTalk2)

The fifth one is "Yukkuri-type" voices (AquesTalk2).

This is used as the speech synthesis engine for software and services like Bouyomi-chan.

The older version of AquesTalk bundled with Bouyomi-chan can be used for free, regardless of whether it is for-profit or non-profit.

However, if you use software incorporating the current AquesTalk for commercial purposes, you must purchase a license.

The license fee is 6,380 yen (including tax) per year.
