As regards the volume, does it turn off in the case of using the timer when giving a public speech?

Beth, you can't turn it off but you can turn the volume way down. I don't think it will work for you, although you can't hear there is a red flashing light that you can't turn off. hope this helps. I use it for baking. don

Can i let this device run at 20 minutes intervals all day without having to reset it manually?

No, you cannot. Once you set a time and start the countdown, it will count that interval and alarm. You must manually stop it, and then reset another time interval. I'm sorry that it will not meet your specialized need, because it is the very best timer on the market.

how long does the alarm sound off? will it stopped automatically?

Also, once the alarm goes off, it begins a count down of how long it has been since it went off so you know how much over you have cooked the item.

What size batteries does it use, and how many does it require?

4 size C batteries. This is THE BEST timer I have ever had....I have used mine for almost two years and not changed the batteries. I use it daily! I cannot say enough good things about this timer.
