Screen Reader/Text to Speech


Text to Speech softwares take visual words and read them aloud to the reader. Recently TTS has become somewhat ubiquitous, increasing prevalent on both android and apple devices (Csapo, 2015). However, research to date has shown inconsistent findings of the effectiveness of TTS with regards to passage comprehension (Strangman & Dalton, 2006). Schmidt (2011) found that listening while reading did not result in improved total reading comprehension over a silent reading condition.Furthermore Meyer (2014) found no significant increases in reading fluency, text comprehension, and time to complete the readings. However, White (2014) offered Students with dyslexia training in TTS software in a small-group withdrawal setting for six weeks, and saw improvements in motivation to read more, improved comprehension, and improved fluency on assessments. Forgrave (2002) also found that TTS was effective and perceived favourably by those who used it, especially in students grade 6-8. Research is clearly mixed and need future clarification.

Screen readers can be thought of as an extension of TTS software. Screen readers are essentially software programs that read the text on the screen, while also offering other functions such as announcing to the user the location of the cursor on the screen, helping the user navigate the screen with their cursor, or announce the location of various items on the screen.The user activates different features or commands though pressing different key combinations (Hot Keys), Braille display, voice recognition, or mouse. The interpretation of the screen is then re-presented to a text-to-speech, sound icons, or a Braille output device. The most common screen readers output the text in a text-to-speech format. Many common operating systems today have built in screen reading features.Screen readers are often grouped with TTS software’s in research as they are both essentially auditory translations of visual stimulus.

Research Rating: Due to the experimental nature of the information cited in this description this information is to be trusted as valid and reliable 


  • Can be used for those users who are more profoundly farsighted

  • Can assist writers in editing and proofreading texts


  • None

To Consider

  • Find the right voice. Having a high quality TTS voice will improve comprehension (Cunningham, 2011).

  • Control the speed at which the voice presents the text. Having the computer present between 140 and 180 words per minute is an optimal speed (Cunningham, 2003, Cunningham, 2011).
