Privacy question

Heard this question a few times: “will my voice end up in a product?”.
Can somebody with technical knowledge elaborate on this topic?

Voice will be used to train NN. It will not be available is any parts of training result, it is not possible to restore your voice from trained model. However, your voice recordings will be freely distributed in dataset. This is the goal of this project - to collect voice data for anyone who wants it for any further purposes.
