Short for text-to-speech, TTS is an accessibility feature included in many computer operating systems and programs. Text-to-speech, when enabled, reads displayed text and generates synthesized speech using various algorithms. This feature can make information more accessible for visually impaired users, or those who have trouble reading words on the screen by audibly relaying the information.
Enabling TTS in Windows
On a Windows computer, the Microsoft Narrator application can be opened to enable text-to-speech narration of all text on the screen automatically. In the application, a settings menu is presented to customize which elements of the screen are narrated.
The Narrator application can be opened and closed using the keyboard shortcut Ctrl+Windows Key+Enter.
