Voice Usage Relatively Stable in Most Age Cohorts, Except Those 34 and Younger

Voice usage per person is roughly stable in most age categories 35 and above, data from Nielsen suggests, at between 400 minutes to 900 minutes a month.

But voice usage per month seems to be dropping in the 34 and younger cohorts, even though younger users tend to have the highest usage, with activity declining steadily in every older age cohort.
