I don't know if assurances is the right term, but everything around machine learning and generation seems to be quite liberal with respecting people's property, so indeed something called "donate your voice" made me pause. Mozilla is probably the right organization for that. Their main product however is dwindling, and I'm not sure what will happen to their data if they ceased to exist. There is a tendency for dying organizations to be pulled apart for scraps, and this would definitely become an IP of interest for a lot of companies with much lesser noble causes
