Visual Tutorial: ImTranslator Application

ImTranslator for Firefox : ImTranslator application

ImTranslator is a standalone application that performs an instant translation of words, phrases and text.  It translates up to 10, 000 characters at once between 91 languages using 3 translation providers: Google , Microsoft Bing, and Translator.


To run the application, do one of the the following:

  • click  imtranslator-smallImTranslator button on the Firefox toolbar  imtranslator-smallStart ImTranslator menu
  • click  imtranslator-smallImTranslator button on the Firefox Tools menu, then imtranslator-smallImTranslator
  • choose  imtranslator-smallImTranslator item from the context menu
  • use shortcut keys: Alt+ Z (default)

Language Detection 
ImTranslator application includes the language detection feature. By default the automatic language detection is enabled.
When you enter text and click the Translate button, the language detection tool analyzes the source text, identifies the language and displays the label "Detected: language".


There may be cases when the language detection tool doesn't recognize the language correctly especially for languages of the same language group, loan-words or short text.  Please note that the accuracy of the automatic language detection increases with the amount of the text entered.

If you know the language of text to be translated, you can disable the automatic language detection function and set the source language manually using Options.

Switch Languages

If it’s necessary, you can manually swap the translation direction using the "Switch languages" button.


Back Translation

The back translation, if checked, translates the target text back to the original language.


Comparison of the back translation to the original text is sometimes used as a quality check on the original translation.

Although the back translation doesn't always provide the same translation result due to the asymmetric sentence structure in different languages, this feature may give you additional benefit to make sure your text is understandable.


Text-to-Speech in ImTranslator converts text into voice for 10 languages. You can listen to the original text or its translation.
Click the "Listen" button to initiate the voice.


ImTranslator supports the following voices: American English, Chinese, French, German, Italian, Japanese, Korean, Portuguese Brazilian, Russian, and Spanish.
Pressing the Speaker button will redirect you to the ImTranslator Text-to-Speech online service. These voices can speak up to 1000 characters at one time.
