If you listen to the first English example here, and then the first Swedish example, you might hear that the Swedish /d/’s are much more dental than the English ones. The /d/ should be pronounced with your tongue in the same position as when you’re producing an [s] sound.
Edit: I should add that this does not go for all Swedish accents, but it goes for Stockholm and the accent of the TTS. Notable accents with the ’English’ non-dental [d] are e.g. Skåne, Gothenburg, Dalarna, Finland and others.
