pawn Code:

public OnPlayerText(playerid, text[])
{
   ApplyAnimation(playerid, "PED", "IDLE_CHAT", 4.0, 0, 0, 0, 1, 1);
   SetTimerEx("StopChat", 1000, false, "i", playerid);
   return 1;
}

forward StopChat(playerid);
public StopChat(playerid)
{
   ClearAnimations(playerid);
   return 1;
}

Something like that.
