Smash 3DS Question concerning Pokémon sounds unlocks

[Aeruon]

I'm currently 100% completing SSB-3DS and I have 2 challenges, 4 Milestones (not tied to Challenges) and one personal achievement ("Have played with all characters online!") to go! So what I was wondering, is if I actually have unlocked all Pokémon sounds. I currently have 42. There's a notification saying you have unlocked all Pokémon sounds, but since it isn't a Milestone, you can't check you've got it. Sooo... I have unlocked all Pokémon, and I think it is very likely you unlock the Pokémon's sounds upon unlocking said Pokémon, à la Kirby's enemy's voices. But you know, there's also the chance you unlock Pokémon sounds when said Pokémon came out of a Poké or Master Ball in battle. Ooor (very unlikely) you unlock Pokémon sounds another way.
Most likely, I got all sounds, but I'm asking for confirmation. You know, just in case. Thanks in advance!

Hmm, I think you've unlocked them all.
