What?
Push To Talk Release Delay, for the voice chat in dayz standalone.

Why?
Whenever speaking, players often release the button before they finish their sentence or the last word, making the ends of words cut off.
Having this set to 0.5 seconds by default, would improve the experience of the players who receive the voice chat immensely.

How?
Push to talk release delay, delays the release of voice communications for (usually) 0.5 seconds,
after the button for push to talk is released.

Having this set to 0.5 seconds by default and having a slider for this option in the game settings would allow players to choose their personal push to talk delay.
