[Regarding Recent Technology Advancements]

I have a particular use case for AI that I'm interested in getting others' opinions on.

I'm working on revising and remastering a piece for resubmission. I perhaps too ambitiously decided to feature a choir singing Irish. In my original mix I tried very hard to finagle EW Hollywood Choirs' Wordbuilder system syllable by syllable based on online audio recordings of each individual word, but after hours of work I'm not very happy with the result. It's not a huge deal, since epic choirs are not usually expected to be understandable, but I worked hard on the lyrics and translation and I'd love to hear them more genuinely represented in the final version.

Lately I've been eyeing AI voice transformers. It appears possible to record myself singing Irish, transform my voice into a handful of AI-generated voices, and layer those with Hollywood Choir's samples to create something that sounds like a choir actually singing in Irish.

In this case nothing would be "generated by feeding a prompt into AI-software." The AI would instead be fed a recording of my voice and would duplicate the notes in a new, generated voice. My creative activity would not be too different from what I currently do with samples of choirs and instruments: every note and expression would be my creative choice, but the actual sound would not be created by me. 

I'm curious what others think about this. AI as a whole generally feels icky to me, not the least because AI companies are notoriously unscrupulous about using others' work for training their models, without compensation. On the other hand, some companies at least claim to be ethical in this regard; kits.ai for instance says that their models are trained using audio recorded by contracted and compensated session vocalists. This seems no different from how EastWest obtained the audio which they sampled for their choirs.

My other option would be to record my wife and try to duplicate her voice with enough differentiation using a variety of filters and effects. My wife is doubtful about this working well, however!

What do you all think? Acceptable use case? Not acceptable?

[Need a Celtic Drums likes Bodhrán VST]

I subscribe to EastWest Composer Cloud. It's not free, but I get it with an education discount and find it to be very valuable for $10 a month. I quite like their EW Fantasy Orchestra bodhrán. You can hear it on this track: 

(Mixing and mastering isn't the best—I'm still learning—but the bodhrán should be pretty audible.)

And also this track (where the mixing and mastering has improved, and also the bodhrán sits in a busier mix): 

So yeah, I'm pleased with their bodhrán!

The subscription also includes a massive amount of other percussion, including Goliath as mentioned by Geoffrey Taucer, which if I remember is actually being used in the above track for the taikos and riqs.
