ɛ is the vowel I use in English "sell" and Swedish "dig".
eː is the vowel sound I use in English "hear" and in Swedish "det".
The problem with providing English examples though, is that there are several English dialects that may pronounce them differently, even if we pretend all Swedes have one dialect. https://en.m.wikipedia.org/wiki/Swedish_phonology#vowels
The voice is not quite perfect on this sentence, as of May 10th, 2018, so I've taken the liberty of re-recording it.
In this case, the error isn't huge. But tycker om is a so-called particle verb in Swedish, meaning that it's one verb consisting of multiple words. If you leave either word out, the meaning usually changes completely. And hence, stressing the right word is important. Almost always, this means putting the stress on the particle - the om, in this case. The automatically generated voice has a tendency to put the stress on tycker instead, which is never correct, or on the word after tycker om.

Thanks for listening. Ha en bra dag! :)
I grew up all over Sweden, so I don't have a clear dialect. That's not to say I don't have a dialect - I think that's impossible - but it's not easily distinguishable based on geographical markers.
The closest would be e.g. that of Uppsala, which is generally considered the most neutral or national dialect.
That depends on your English accent.
dig = /dɛj/ , day = /deɪ/.
The most common pronunciation for /eɪ/ (found in English face, day, and pain) is not the same as Swedish dig (Which I explained in the earlier comments has the same e sound as in General American English "sell"). However, the standard in England comes out as /ɛɪ̯/ which is pretty much the same as Swedish dig. The standard English spoken in Ireland and in India, where I used to live, speaks that /eɪ/ (found in face, day, and pain) as /e:/ and so when they say "day" it sounds like Swedish det instead of Swedish dig.
Your ears have to learn by hearing though. https://forvo.com/word/dig/#sv
