Differences between English and Finnish, a short article that I thought you might find interesting.

Finnish invariably places primary stress on the first syllable of a word, and the stress does not significantly affect the vowel quality. This is in stark contrast to English, which has fairly unpredictable stress patterns. It is not surprising, therefore, that beginning learners may fail to make themselves understood even if the grammar and vocabulary of their message is correct. Finnish intonation is typically falling. This can make it difficult for them to produce the rising tone of English questions.
