How many words we speak

The number of words people speak in a day varies greatly between people and days. A 2007 study estimated an average of about 16,000 words per day among its participants; a later registered report with a larger sample estimated an average of about 12,800. These are estimates from particular samples, not a universal norm, so 4,800 should not be presented as a general average without a defined source.
