Windows Light (Read Assist) with Speech Output in Chinese and English for persons with Dyslexia


This edition of Windows Light (Read assist) is a screen reading software developed as an assistive aid to help people facing challenges in reading and writing (notably those with dyslexia).  It works by retrieving text displayed on the computer screen and reproducing it in synthesised speech.  With the PC mouse, the user can get his/her target text in Microsoft Word and other text editors read out.  In addition, it also provides a “global screen reading” functionality which enables the user to operate with the mouse to get textual contents in other windows applications read out.


Languages Supported


This edition of the software provides speech output in three languages, namely Cantonese, Putonghua (also known as Mandarin) and English.


Platforms and Applications Supported


This edition of Windows Light (Read Assist) supports screen access in Windows XP onwards up to  Windows 10 (both 32-bit and 64-bit). It also supports text reading with mouse operation in Microsoft Word 2003 up to Word 2013 and in many other text editors.


This is an Upgrade


This edition of Windows Light (Read Assist) deploys the Nuance Scansoft Chinese text-to-speech engines (both Cantonese and Putonghua) for Chinese speech output.  Because a license fee is payable for each copy of the engines, the download provided here is the latest upgrade rather than the full version of the screen reader.  This means that before downloading and installing this upgrade, you must first have installed an earlier version of this software with the Chinese text-to-speech engines.  To obtain and installation disk for such a version, you may contact Retina Hong Kong by phone at 852-27089363 or by e-mail This email address is being protected from spambots.
