Can't tell tones of unknown words

[ChiNewb]

Hello guys, new to this place, hope you can help me.

So, little background: 

I have been studying Chinese for a year now, finished reading/listening/studying HSK4 (HSK Standard course, 标准教程), and am doing HSK5.

So, the problem as it is: most of the times, I can't tell tones of new words I encounter while listening. I have tried different doing tone drills ( I get an excellent result there, but their pronunciation is way too artificial). It is kinda ridiculous, for instance : if I look up its tones, then I immediately notice all the attributes of these tones, so it becomes clear. Recently, I have been immensely worried about this, and started doing more listening (youtube, lingQ, some HSK listening practice apps). Also, no matter if it is a "clear" audio tape or a youtube podcast material, I struggle anyways.

Is it a matter of practice, so I should simply listen to different resources?
