Is it just the game or.......

Wassup ? I'm new here & this is the first topic that i posted so far.Anyone got their hands on Megaman ZX Advent DS game ??When i played the game the conversation voice seems so...., y know it sounded like talkin in the phone,but sometimes the voice is clear on some events.Is it my ROM that rusted or it's just how the game works ?Man i'm really stuck, if anybody knows about this problem please reply !

how are you playing the rom? (emulator/flash cart?)It will not be your specific copy of the rom.

Well....., i'm using SD supercard Rumble and standard supercard SD. I got 2 since there are some games that
can't be played in my normal SD (ex: Castlevania POR).I played the game in my Rumble version, cuz usually it's lagging in my SD.
