Advanced Voice can definitely sing!
I got it to sing by asking it to respond in the style of a character from Les Misérables.
How do you get it to sing?
You can encourage it to sing by framing your request creatively.
For example, you might ask it to respond as if it’s a character from a musical or a specific scene where singing is involved.
Alternatively, you can suggest it perform a song or express something in a lyrical style, giving it a clear cue to sing.
