I think the recitation and sawab part in Hadiths which are qouted above may have assumed that the person knows the meaning of Quran and has understandig of Arabaic language.
Some people may not like it and apologize for that but I personally feel reciting Quran without even knowing the meaning of what is being said is just does not make sense.
**Tafseer is just another step in understanding the Quran better but one has to at least know the meaning of what one is reciting.

Traditionally speaking recitation is done in such a way that the person feels good about reciting (while nodding his/her head) as fast as he/she can with absolutely no idea what was even recited.
And many people don’t even know 10% of Quran by its meaning and live a whole life reciting the book a hundreds time!
