The course book publisher Otava has a service called Otso application for the Oma Suomi 1-2 books. With this application you can listen to recordings of the book.
Download the Otso app to your phone from the App Store. Scan the cover page of the book (skannaa kansi) or search for the book (hae kirja) and then you just point it to a page in the book and the application recognizes the page and starts playing the recording.
The contents of the “student recording” are available, i.e. the texts of the chapters and the pronunciation exercises, but not the listening exercises.
