For me, listing to the audiobook at the same time is how I increase my reading speed. My reading-only speed was 100-110 or so wpm and I thought this was too slow, so I decided to get the audiobook. Now I’m listening to the audiobook on 1.4x (205 wpm). However, I have to reduce the playback speed to 1.3x (190 wpm) or lower when my concentration is low or I’m tired though.
Exactly. Let’s run a rough calculation.
My extensive reading speed: ~200 wpm
@GMelillo’s ‘semi-extensive’ reading speed on LingQ: ~100 wpm
@GMelillo understands 100% of unknown words, as he looks them up in the dictionary
Let’s assume I can only guess 30% of the unknown words from context
If we assume the texts have the same number of unknown words and you need to be able to understand the word to learn it, then the increase in the reading speed would not compensate for the reduction in unknown words understood.
Eg. If both people read for 10 hours and we assume on average 1 complete unknown words per 100 words:
Me: 200 wpm * 60 mins * 10 hours = 120k words read
→ 120k * 1 unknown word / 100 words = 1.2k unknown words
→ 1.2k unknown words * 30% = 360 unknown words with meaning understood, so therefore are able to be processed and started in the learning process
@GMelillo: 100 wpm * 60 mins * 10 hours = 60k words read
→ 60k / 100 * 1 = 600 unknown words
→ 600 * 100% = 600 unknown words with meaning understood
Obviously it doesn’t exactly work like this, because you don’t really need to understand a word to start learning it, but it goes a long way.
So in this example, we can see that @GMelillo’s ‘semi-extensive’ reading with a dictionary on LingQ would be more efficient to learn completely unknown words. However, if we use my reading speed on LingQ (55 wpm, so about half of that of @GMelillo’s), with this rough calculation, it would not be! In other words, reading speed is a major factor. Furthermore, studying material on LingQ, you are highly likely to have more unknown words than that during extensive reading.
In this rough calculation, we can also see that the thing to do to increase the effectiveness of extensive reading is to try and find texts, where you can understand more unknown words from context. Eg. Read translations of books you’ve already read in another language, or non-fiction books on a subject you already know, etc.
Furthermore, what extensive reading has going for it is that because it’s much easier to do than semi-intensive reading and likely to be more fun, you may just end up doing more of it. I.e. studying an extra hour per night.
But the real benefit of extensive reading is drilling in the words, which you’ve already started to learn. For this reason, it’s likely to be more effective once you are better in the language, as there are more words, which you are in the process of learning (eg. I have 35k lingQs which I’m still learning).
That’s what I think when I’m writing a definition for a low-frequency word, which I’m never going to see again…
