Using a voice synthesizer plugin with Musescore 4?

I'm working on a piece with a few vocal lines, and I'd really like to hear it with the actual lyrics rather than"oooh" and "aaah" to verify/fine-tune the phrasing and (hopefully) create a decent demo. Since I don't have any singers handy (and, like Leo Kottke, my voice sounds like "geese farting on a muggy day") I'm wondering whether a voice synthesis plugin might do the job.

Ideally I'd like something that can read the lyrics for a part, but to get pronounciation right the actual text input would look very different ("unionized" means and sounds very different things to chemists and labor organizers), so I expect this would require separate tracks (hidden in the printed score) with the phonetic lyrics.

In particular I'm looking at Synthesizer V from Dreamtonics (https://dreamtonics.com/synthesizerv/), but I'm open to any solution that's A) inexpensive (I'm retired, this is one of my hobbies), B) sounds resonably natural, and C) has multiple voices available for the different parts.

Does anyone out there have any experience with something like this? Is this possible/practical, or just wishful thinking on my part?
