Perhaps you would consider offering your audio files for offsite use, too, with a Creative Commons License.
If you do not choose a license, then the default is "no license for offsite use."
The most popular license at this time on tatoeba.org is CC BY-NC 4.0 . https://creativecommons.org/licenses/by-nc/4.0/
After April 2022
For some reason, the default was changed from an opt-in to a license to a CC BY 4.0 license by default. This means that you may want to change this right away if you are a new audio file contributor.
See the "license" under "My Audio."
Choose the license that you want.
At this time, I think the most popular license is CC-BY-NC 4.0. This means that people cannot use your audio file for commercial purposes (to make money).
I would recommend choosing "no license for offsite use" if you are not sure at this time.
You can always give more rights in the future, but it is not good to take away rights after you've given them. People might consider that unethical.
