Paid Text-to-Speech Software: Commercial Licenses & YouTube Use Explained

When someone aiming to become a YouTuber decides to use "text-to-speech software," the most concerning issue is 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 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 in violation of its terms,

• Videos may be deleted, or accounts may be suspended,
• Complaints may be received 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 terms.

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

When comparing multiple software programs,

• which ones are OK for commercial use,
• which ones are NG,
• and 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.

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 also OK)

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

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

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

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

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

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

AI Talk

The second one is AI Talk.

A well-known text-to-speech software developed by AI Inc.

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 permitted."

However, looking closer, it states, "Use on video-sharing sites (YouTube, etc.) as narration for Web video works is OK."

Generally, for individuals, use for earning advertising revenue from view counts on YouTube is allowed under the standard license.

However, use for video creation received as paid work, or videos with sponsors where rewards are received, is considered commercial. These cannot be used within the scope of the standard license.

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

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.

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 sound sources high originality.

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

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

Great care is required as the permissible range for commercial use also differs.

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

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

• Sato Sasara,
• Suzuki Tsudumi,

Regarding commercial use, specifically for use in video posts like YouTube, let's check the terms.

It states:

"For use in video posts, if an individual or doujin circle posts and earns advertising revenue, it can be used for free."

For acts like an individual posting videos to YouTube, it can be used without purchasing a commercial license.

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

Note that for video creation undertaken for a fee, a paid commercial use license is required. The license fee requires an estimate. The specific amount was not listed.
