We present an open source web app for practicing the pronunciation of words in low-resource and commercially less-interesting languages. Since it is web-based it works on all platforms: MS Windows, Mac OS X, Linux, Android, iOS, etc. The web app is device independent and works on desktop computers, laptops, tablets and smartphones. The app will become available as open source software and in the public domain as a generic application. i.e. with minimal effort the app can be adapted so that it can be used for any language when recordings of a series of words pronounced by at least one reference speaker are provided. The app has initially been developed for Latgalian and West Frisian. Latgalian is an Eastern Baltic language and mostly spoken in Latgale, the eastern part of Latvia. West Frisian is a Germanic minority language spoken primarily in the Dutch province of Fryslân.
