It seems to be Swedish in origin, in which case the closest English equivalent would be "mee" or "mew".

Roughly speaking, the <y> here is close to what is traditionally transcribed in English as [i:], except rounded, i.e. [y:].

Many caveats apply, this probably being Finnish Swedish (which should have the same or a similar vowel), my Swedish being rather rudimentary, etc.
