Voicing the words,as you write or read...How to stop it?
It wastes a lot of energy, and limits the speed....
any other tricks than singing... cause I also need to comprehend the matter
One of the things that really helped me speed read and have realistic expectations was reading 10 days to Faster Reading by Abby Marks Beale (find her on amazon) ...
I became a fan .. one of things that she recently came out with is "10 Minutes to Faster Reading" - a free pdf download .. really good for those who are starting out and goes over some of these issues .. such as sub-vocalization.
If you are interested you can also take her Rev It Up Reading online speed reading course.
Anyway here is the link to download her free ebook!
As for your vocalizations, I wouldn't necessarily think of them as an issue that needs to be fixed.

Here are two suggestions:
I like EyeQ best, because it has better structured exercises.
To answer your question: The apps have exercises like chunk reading, widening your field of vision and pacing. You can do each exercise on your own, but it is more effective if the program forces you to follow the rules. During the courses you will read faster and thus give up voicing automatically.
Besides humming or singing while you read, you can also learn to recognize chunks of words at a time. I took a speed reading class that did exactly that - once you can recognize and comprehend three to five words at a time, you can skip the vocalization.
Let's look at this paragraph again in chunks:
Etc. Basically, take a speed reading course and learn chunking. They should throw different, but commonly found "chunks" at you, the only difference being specific nouns. The idea is that you can recognize the chunk's meaning and focus on the nouns or specific differences.
EDIT - About halfway through this page is a description of how you can learn chunking on your own:
