Sao Mai Braille (SMB)

Another powerful tool for Braille transcribers to quickly format and translate popular document types for their Braille production! SMB utilizes a well-known LibLouis library for the translation and has its own built-in formatter with styles to handle Braille formats.

Sao Mai Music Reader

SM Music Reader Logo

The first free Android app to support both sighted and visually impaired people to read same music scores! With its very unique features of drawing, playing and speaking, we hope that there will be no more gaps between the sighted and the blind to read same music scores. More new features such as voice commands, Braille output and more others will be developed in the near-future releases.

Sao Mai Typing Tutor (SMTT)

An inclusive environment for not only blind computer beginners but also for the sighted to learn and improve their typing skills. Lessons are easy to customize or add new with its own lesson builder tool; and computer instructors can easily keep track of their trainees’ learning/practicing activities via the user manager.

Sao Mai VNVoice

The first Vietnamese SAPI-5 speech engine for Windows built with two female voices, Minh Du and Mai Dung and has been used by visually impaired users in Vietnam for years.

Burmese Text-To-Speech Engine for Myanmar

This project was built and has been coordinated by the Sao Mai Center for the Blind, with the implementing collaboration of the NHM Team and the Myanmar Assistive Technology Research and Development Center. The project is sponsored by The International Council for Education of People with Visual Impairment (ICEVI), the Overbrook-Nippon Network of Educational Technology (ON-NET) and The Nippon Foundation (TNF).
The Burmese TTS is developed for Windows platform, complying with SAPI standard so all Windows screen reading software like NVDA and Jaws should support and read Burmese documents. The TTS also has feature to let users configure the second voice to read text written in other languages than the Burmese default one.

DoudouLinux - An Educational Game System for Kids

In 2014 Sao Mai Center, with Sao Mai Education Fund and Mantovan Association of Bolzano, Italy, outlined a new project to benefit Vietnamese children. The project consists in the Vietnamese translation and localization of software for children to develop their cognitive, motor and social skills. The product is called DoudouLinux and is already available for download in more than 40 languages.

NVDA: Vietnamese Screen Reading Software

NVDA is a free and open source screen reader program for Windows, developed by the NV Access and its community. Since the early development period of NVDA, Sao Mai has been working closely with NV Access to develop add-ons and localize NVDA into Vietnamese.
In 2018, we worked with NV Access to translate their training modules with NVDA into Vietnamese, including the NVDA basics, Microsoft Office with NVDA (Word, Excel and more to come). With the hope to have a productive and supportive NVDA user community in Vietnam, Sao Mai has published one official website at We are looking forward to more and more visually impaired users to join!

Other Sao Mai Soft (no more development)

Since our establishment in 2001, we developed some other applications designed intentionally for blind users in Vietnam. They are all free. Most of them are and standalone talking applications such as DictTalk (a dictionary based on Dict standard), CalTalk (quite similar to calculator devices which are accepted to use at schools in Vietnam), EditTalk (word processor), NetTalk (a web browser) and WinTalk (a basic screen reading software).

Due to different reasons in the past like with limited finance support, we could not continue further development and they are mostly out of date with today technologies. However, we are quite happy for such products as they were somehow among the helpful tools for the blind for few years in the past.
