I think you'd have to do it yourself, involving a lot of research. Not even SH5, the latest in the series has such a voice report.
For immersion feeling, when it is raining on screen, go stand in the shower (cold water) for five minutes and then return to the game. You cannot change or dry yourself until you dive. (towels on the floor)
Don't forget red light bulbs for night. Open all the windows to let in air, regardless of outside temp. Close them and all doors when under water.
Stand, not sit, to run the game. Enjoy !
