If you could double the words read per minute, you would half the time it takes to read any given text.
Speed reading refers to a number of techniques used to improve the reading speed significantly. When it comes to techniques, several can be used.
Skimming for instance is a method in which one scans paragraphs or pages of text quickly to find the meaning without reading all of the words.
Another popular theory is that subvocalization, that is the inner vocalization during silent reading, slows down the reading. Elimination of it would therefore improve the speed in which text is read.
Spreed for Google Chrome is a speed reading extension for the browser that aims to help you read text faster that you encounter on the web.
It does so in its own interface that you can resize to your liking.
There are two options to load text into the interface. The first involves highlighting text on a website and using the Alt-V shortcut to load it automatically into the extension's interface, the second to highlight text, right-click the selection, and load it this way into it.
One word is displayed at a time and 400 words are displayed per minute when you hit the play button. If you are new to speed reading, this may be too fast for you.
You can use the controls at the top to reduce the words per minute count. The count goes down or up in 50 words per minute chunks only, so keep that in mind.
Note that the speed is automatically adjusted when you hit the plus or minute buttons in the interface.
Here you can also increase or decrease the words at a time count -- default one -- and the font size of the text displayed in the extensions interface.
Last but not least, it is possible to invert the color scheme so that black text is displayed on a white background.
You can toggle play with a tap on the space bar or a click on the play or pause button. The hotkey l enables you to restart from the beginning, while q closes the window.
The interface is quite noisy, with all the text displayed at the bottom of it. You can resize the window to hide the lower part of the interface. Since you can use shortcuts to control playback, that should not be a issue.
Spreed is not teaching you how to read faster. While you can use it to adjust the reading speed to improve it over time, it does not teach you how to do so. If speed reading is a new concept for you, try this guide which teaches on method.
