I use a dedicated olympus voice recorder. I have an activity that means I have a recurring need to make voice notes on my drive back from it. The voice recorder is great because it's easy to operate by touch as opposed to a touch screen. You hear a beep when it starts so you know it's recording. Recently I have been playing with this script someone wrote to transcribe them into org mode markup files using google speech to text services.
