Note particularly the italicized phoneme (eɪ), which corresponds to the "long A" sound in English, e.g., the 'a' in 'face'. I'm unfamiliar with the Icelandic language, but according to the English equivalents listed on Wikipedia's page on IPA for Icelandic [1], the corresponding phoneme in that language appears to be ei.
