Step 1 : Introduction to the question "On average, how many words do most people speak in a day?"
There are about 6,000 languages actively spoken around the world. While different conditions affect how much a person actually speaks, a study by the University of Arizona found the average number of words most people speak in a day is 16,000. The study found no significant difference between the number of words spoken by men and women, contrary to some popular myths. The study tracked its participants for an 8-year period, with each subject wearing a device that recorded the number of words spoken every 12.5 minutes while the subject was awake.
