@Planobilly It's an advantage to be able to speak the language well that SynthV singers are supposed to sing. Since SynthV works with phonetic sounds, almost any language (with an accent) is possible, I did it with Asereje and it sounds quite useful. However, it involves a lot of manual rework. You can also simply sing the lyrics yourself and then import them into SynthV using Praat (a free add-on tool).
