You have to go into Extra Content on the main menu and select VOICE and purchase all of the items here. It costs 605,000 points to buy them all and you earn those points by going to Extras, Play Game and playing through that game until you can't complete the stages which give you large chunks of bonus points anymore.
After I got stuck in the normal stages, I used my CronusMax to automate the rest of the points in Free Play. Here is the script I used. It runs for just under a minute and restarts, getting about ~900 per run or about 50k/hr. Just get to the menu where you can pick stage select and click the right stick (R3). Click it again to stop it.
If you don't have a CronusMax, essentially what this macro is doing is just pressing the following sequence over and over.
You can do this yourself manually while watching Netflix or something as it's pretty mindless. If doing it manually, just keep doing this until the game ends and start again. The script stops after 50 seconds or so so that it can predictably navigate the menus.
Onto the Cronus script:
int onoff;
int comboA;
int comboB;
int comboC;
int stage;
main {
if(event_press(PS4_R3)) {
stage = 1;
comboA = 1;
comboB = 20;
comboC = 1;
onoff = !onoff;
}
if( onoff ) {
if (stage == 1) {
if(comboA) combo_run(START);
}
else if (stage == 2) {
if(comboB) combo_run(LOOP);
}
else if (stage == 3) {
if(comboC) combo_run(END);
}
}
}
combo START {
// select Free Play from menu
set_val(PS4_CROSS, 100);
wait(50);
set_val(PS4_CROSS, 0);
wait(2000);
comboA = comboA - 1;
if (comboA <= 0) stage = stage + 1;
}
combo LOOP {
// the bulk of the macro that will repeat
set_val(PS4_DOWN, 100);
wait(50);
set_val(PS4_DOWN, 0);
