ATbar for Windows Help

ATbar icon labels


This will read aloud text using a voice installed on your computer. If you wish to see the text being read aloud turn this option on in the settings, to display the reading window.

To hear text read aloud first copy it to the clipboard. First select the text then copy it by using a shortcut key, usually Ctrl+C, or through the context menu by right-clicking.

Then select the speak button. You should hear your coped text read aloud. As text is being read, the speak button changes to a pause button.

Select the pause button to stop the speech. Selecting the button again will re-start the speech from the same point in your copied text.


Once you have listened to your text, you can empty the clipboard by selecting the Clear button.


If you need to hear maths equations read aloud, you need to use software that can interpret the symbols and equations into speech. You can use ATbar with STEMReader, an application for reading aloud maths equations which has a free, basic version. Copy equations in MathML or LaTeX to the clipboard and then click the Maths button in ATbar. If you have STEMReader installed, you will see and hear your equation. To find out more about making accessible maths equations that are compatible with assistive tools please read the Accessible Maths article from STEMReader.


This will apply a colour overlay effect to you monitor. You can set the colour and level of transparency within the Settings.
