Humans can typically listen and comprehend speech at a rate of around 210 words per minute (WPM). This is about twice as fast as the average speaking rate.
While typical conversational speech falls in the range of 100-150 WPM, trained listeners can comfortably understand speech at approximately 2.0x normal speed, which translates to the 210 WPM mark. This allows for efficient comprehension and retention of information.
Here's a breakdown:
- Average Speaking Rate: 100-150 WPM
- Comfortable Listening/Comprehension Rate (trained listeners): ~210 WPM (2.0x speed)
It's important to note that comprehension accuracy decreases significantly when listening speeds are pushed much beyond this 2.0x (210 WPM) mark for sustained periods. While the brain might hear the words, processing and retention suffer. Factors such as accent, complexity of the material, and individual differences in auditory processing abilities also play a role.
Therefore, 210 WPM is considered a practical and effective upper limit for comfortable listening, comprehension, and retention.
