If you stand near Yoshiro, you'll hear her vocals on the battle track. (Only the 4 main ones)
Yoshiro's vocals are her actually singing when you stand by her. She'll stop dancing to sing if you're close enough. It looks like she's actually meant to be singing specifically for Soh.
But she only does it when it's time for her vocals during the battle track or she'll just keep dancing.
Even in the mikoshi.
