It would take a very long time to count to a million out loud, especially if you were speaking at a normal pace. It would take approximately 23 hours to count to a million out loud, assuming that you are speaking at a rate of one number per second.
However, this is just an estimate and the actual time it takes to count to a million out loud could vary depending on a number of factors, such as your speaking speed and any interruptions or pauses you might take while counting.
