Dictionary converter

About

This app converts various sources into dictionary format suitable for e-readers. Currently only kindle format is supported.

As an input you can specify tab delimited file, tab delimited pronunciation files and wiktionary data. All sources can be specified at the same time and the app will mix them in one dictionary.

The internal structure of the dictionary is "word class" -> "meaning" -> "translation". However, kindle presentation is for clarity and more concise display organised differently.

Where to get dictionary data

• Wiktionary

  Download latest English Wiktionary backup file from: Wikimedia Downloads search for enwiktionary, click on it and on the page find pages-articles.xml.bz2 file.

• Pronunciation files

  There is a project on github.com collecting pronunciation data. Go to ipa-dict
