Zhengdu Screen reader: Official User's Manual; Version 126.96.36.199
Chapter I: Introduction
Hello and welcome in the official user's manual for the Zhengdu Screen reader,
known also as ZDSR throughout the rest of this document. This book shall serve
as a complete guide for the Zhengdu Screen reader, all its features, functions
and use cases, but shall also serve as an instruction and a guidebook for
sighted teachers, trainers, assistants, and parents wanting to understand how
blind people operate computers.
The book's design allows reading either chapter by chapter, or just specific
chapters needed by the user. This approach allows novice users to slowly
familiarize themselves with all the terms and operation methods, while letting
the intermediate and advanced users skip straight to the specific chapters
concerning their specific needs.
We sincerely hope that you will enjoy this manual and the software itself and
that Zhengdu Screen reader will improve and enrich your daily life.
Let's strive for perfection together!

What is a screen reader?
Putting it simply, a screen reader is a software program installed on the user's
computer that "reads the screen". What it exactly means though is that the
application installed on the computer collects textual or even non-textual
information and conveys it to the user via another application installed on the
computer that is called a Text To Speech engine or TTS in short. There are many
Text to Speech engines available on the market. They differ in their voice,
pronunciation and of course price. Do not worry though, the latest version of
the Microsoft Windows operating system contains many voices in many languages,
so your computer is most probably "able to speak by default". If you are using an older
version of Windows though, you will need some special preparation before using
the screen reader.
If you speak English, Russian, Ukrainian or Esperanto we recommend the RH
Voice Text to Speech
Engine. It is free and has some clear voices to choose from. In any other case
we can recommend ESpeak. The
robotic voice of this engine requires some training to get used to, but in
return it provides over 80 languages to choose from.
You might be wondering, if there are so many screen readers to choose from, why
choose this one amongst its competition? The list of notable features is
outlined below. Keep in mind though that this is just a little foretaste of what
you are going to see later.
Speed of operation: blind people have slower access to computers than their
sighted counterparts. ZDSR developed an extremely fast speech engine
increasing the reaction speed by about 300% comparing to its competition. This
makes ZDSR a perfect choice for people who need to access the information as
fast as possible.
Ease of use: ZDSR is built on top of extremely logical and straightforward
foundation, allowing people of all levels of computer knowledge master the
product quickly and efficiently, making it possible to install it and start
Advanced and well-thought functionality: ZDSR has all the functions you need,
plus many more! With the built-in translation, Optical Character Recognition,
automatic labeling of controls and plethora of many different features carrying
out even a most advanced task is not a problem anymore.
Great support for the professional software: Are you a writer, programmer, data
analytist or an audio engineer? ZDSR has you covered. With its great support for
the software like Visual Studio, Android Studio, Eclipse, MS Word, Excel, PowerPoint
and many more the software is not only read perfectly, but also starts being
friendlier to the user with many additional keyboard commands.
As you can see there are many reasons why you should choose ZDSR over any other
screen reading product available on the market.
ZDSR editions and differences between them
The product is available in six different editions. They differ in
functionality, recommended use environment and the method of activation. All of
them are outlined below with their short descriptions. The full breakdown of all
the differences will be outlined in the table further down this chapter.
ZDSR Public Welfare Edition: This is the free edition of the screen reader.
It has only the basic functionality required to operate the computer
successfully. Its use is recommended when you need the computer to carry out
only the basic tasks and you do not have the money to buy the higher-end
ZDSR Youth edition: The most affordable (costing 10 dollars) edition of the
screen reader. It contains basic features like the Public Welfare edition,
plus some useful extras which can boost your productivity. This edition of
the screen reader uses the online activation method, meaning that only the
Internet connection is required to use the program.
ZDSR Youth Plus Edition: This edition of ZDSR contains many features
available in the highest possible edition. If you do not need support for
the professional software like MS Office or Reaper, this version will most
probably meet your requirements. - This edition of the screen reader uses
the online activation method, meaning that only the Internet connection is
required to use the program.
ZDSR Youth Pro edition: This edition contains most features found in the
Business Edition, including support for all of the professional software
like REAPER or MS Office. It is missing some advanced and diverse features
such as "Screen Navigation", but this edition is sufficient for most general
and professional use cases. - This edition of the screen reader uses the
online activation method, meaning that only the Internet connection is
required to use the program.
ZDSR Business Edition: This edition of the program contains all features
from the previous editions plus some features unique to it, like the
forementioned "Screen navigation". What's more this version of the program
does not need Internet connection to function, as it uses a special device
called a Dongle which is plugged in to your computer and serves as the
ZDSR Local Network Edition: This edition of the software contains the exact
same feature set as the Business edition. The only difference is that this
edition is more suitable to use in schools, libraries, and other public
institutions, as it can be running on multiple computers connected to the
same master computer through the network.

needs of the different users. Shall you need any help choosing a right edition
