- What it measures
- A unit conversion to make the scale of the training data easier to picture. It assumes audio that plays without a break.
- How it is calculated
- 680,000 hours / 24 hours per day / 365 days per year = 77.6 years
- What it does not show
- A calculation, not a figure from the paper. The training data is spread across many languages and recordings, so no single listener heard all of it.
