"Interesuję się chemią."

Translation: I am interested in chemistry.

What case is 'chemia' in? Could anybody please tell me how to say 'I am interested in psychology and linguistics'

[Jellei]

Instrumental. If you're interested in something, that's Instrumental.

Interesuję się psychologią i lingwistyką/językoznawstwem.

Don't forget that there are no such things as silent "p" in Polish ;)

[MeganKunze1]

Thank you! :)

The female voice version sounds like a question to me. The male voice version is definitely a statement. Does anyone else hear the female voice asking as a question?

[Jellei]

Yes. The intonation is generally a big problem of the TTS. The male voice is newer, and for this reason more advanced, but it's also not free of faults.
