When I’m trying to spam skills in the middle of battle, it gets really annoying to hear, “I can’t do that yet” or “That skill is not ready” constantly being repeated. But as of right now, the only way to get rid of that annoyance is to turn off all voices in the game entirely. I’d love to see an off/off toggle button offered so that we can turn off the player character’s voice while in game.
Agreed. I always feel like, “Okay, I GET it, but I need you to do it the second it gets off CD, and I can’t get you to just do that when you CAN cast, so I’m gonna spam it! SHUT UP!”
It’s literally the only reason I make all my characters female, because that voice is slightly more tolerable when it starts repeating that all the time.
I don´t even herat that anymore. 
Yet I get it, it can be annoying.
A toggle for music on/off would also be nice. 
There is already a music volume slider in the game under the audio settings. I agree with evvie that it would be nice to have a toggle that only applied to the character voice so i could still listen to story dialogue. The only things the player character’s voice does in game is grunt when you get hit hard and constantly remind you that a skill is on cooldown, and since there is already a popup on screen for that I could really do without the constant vocal reminder.
