not sure. I hope so. But I just bought both codeFactory eloquence vocalizer nvda-addon license, and vocalizer sapi5 license, and I am patiently waiting for my license keys to arrive. I already own two sapi5 eloquence keys, and I back up my important order information onto google drive so I do not lose it. I bought sapi5 vocalizer so I can have some good voices for audio games. But I am on a tablet with limited storage so when I install vocalizer voices I will install the smaller voices which are about 60mb per voice, rather than the full voice which is around 300mb per voice.
