The reading time is calculated by dividing the word count by the average reading speed of 250 words per minute (wpm). For example, 3,000 words divided by 250 wpm equals 12 minutes of reading time.
The speaking time is calculated by multiplying the reading time by 1.3 as the average person reads aloud 1.3 times slower than they can read silently. For example, a reading time of 12 minutes multiplied by 1.3 equals a reading time of 15 minutes and 36 seconds.
