He may be, however, remember some of the portions of what’s being used may be licensed under another type of license, which then calls into question the legality of the add-on as a whole.
If google in fact have not in any way released the tts to be used for any purpose other than its intended purpose, then the add-on is in fact illegal.
Knowing what the license is, helps the rest of us understand if the add-on can in fact be used legally and without consequence.

If it’s an add-on, then I feel that you are being too heavy handed Rui.
It is in fact, legal, parts of it are open source.
All the best

As I have already said, I do not have any problem in users using the add-on.
Just do not discuss it in the group. It is so hard to understand?

It's not hurting anyone, and google has never charged for use of their tts in google chrome or on android. I have been using it all day, and the police haven't shown up at my door yet. Should I call my local state police and report myself for using illegal software?

Hello.
The following text is quoted.
Hi everyone,
Like many of you, I’ve always wanted to use Google's natural-sounding TTS voices directly within NVDA. While there have been a few workarounds in the past, I couldn’t find a completely standalone, user-friendly solution that was fit for daily use.
Recently, I managed to figure out how to extract Google’s WASM speech synthesis engine and built a basic add-on around it. Later, Dao Duc Trung joined the project and helped rewrite the core logic while optimizing the audio processing to make the voices run smoothly. We are now actively developing it together.
We use this add-on ourselves every day and are excited to share its first public release with you today. The project is still in its early stages, but we’d love for you to try it out and share your feedback.
How to try it:
1.
Download the .nvda-addon file from the GitHub Releases page.
2.
Open the downloaded file to install it, then restart NVDA.
3.
Open NVDA’s synthesizer selection dialog and choose "Google TTS For NVDA".
4.
If this is your first time using the add-on, the Voice Manager will open automatically, allowing you to download the voice packs you need.
Known Issue:
Since this is our initial release, there is a noticeable delay during the very first initialization and the first piece of speech playback. We are currently working on fixing this for future updates, so we truly appreciate your patience during the initial setup!
If you encounter any bugs, have suggestions, or want to contribute to the project, please open an issue or submit a pull request on our GitHub repository. You can also contact us directly.
