The voice starts out like a gunshot. Look at your waveform. It shouldn't start with a spike, but I gaurantee it does. It can be shocking. All quiet and then "In one mile, turn left" But it goes from silence to WAAAAY TOOO LOUD way too fast. It is an assault on the ear drum. By modulating the waveform ever so slightly, you could remedy this, but it's been like that as long as I have used Waze. There needs to be a few hundredth of a second of sound buildup so you don't give the driver a heart attack. I cannot believe you guys haven't done something about it. It is a glaring issue.
