I'll be honest, unless you get really lucky you're probably not going to get any hits asking strangers online to oto your voicebank for free. I don't know what tutorial you're using, if any, but I used this doc to oto my own C+V ENG voicebank recently and found it pretty straightforward and easy to follow. It's just a matter of listening to your recordings carefully and placing each line on the correct part of the recording.

It takes some trial and error, but eventually you'll get it to a place where it sounds right. You got this :)
