Mart Dictionary

Mart Dictionary is a translation tool with support for multiple languages, along with the Oxford, Merriam Webster and Britannica Concise dictionaries for offline usage. It has an autodetect feature and a text-to-speech function.

Requirements and dictionary resources

Before proceeding any further, you should know that this program hasn't been updated for a long while, and it doesn't work on Windows editions past Vista. It requires .NET Framework 2 and Adobe Flash Player ActiveX, which are included in the package and automatically deployed at installation.
The English-to-English, Mongolian-to-English and English-to-Mongolian dictionaries are available, while additional ones can be downloaded from the developer's website, such as Arabic, German, Chinese, Dutch, French, Greek, Japanese, Korean, Turkish or Spanish (to and from English). These languages get automatically integrated into Mart Dictionary at setup.

Multilingual text translation and word definitions

The utility gets launched in the systray and provides quick access to its configuration panel with four primary areas: dictionary, translation service, text encoding conversion, and settings. This window can stay on top of others.
All you have to do is select the source and output language, enter text, and click a button to instantly translate it. A button is available for swapping the two languages. Unfortunately, the application doesn't implement an option for loading text from files.

Text-to-speech and autodetect features

The dictionary is equipped with a basic search function and displays word definitions in the specified languages. You can activate the speech service to hear word pronunciations, convert ArialMon to Arial/Cyrillic to Unicode text, as well as copy and paste information. Another notable feature is represented by autodetect, an option that allows Mart to automatically translate text selected in any other desktop application.

Conclusion

To sum it up, Mart Dictionary could be a reliable desktop assistant for translating text and accessing multi-lingual dictionaries offline. Unfortunately, it cannot be used on newer Windows.
