I think that most courses which are teaching basic vocabulary will sound a bit robotic but they seem to be good at teaching someone the basics of at least how a language sounds.
There is also a Teach Yourself book with a set of tapes and a Colloquial Polish by B.W. Mazur also with tapes that is very good. I bought a brand new copy, unused for £1 pound fifty pence at my local car boot! I will never use it and you can have it for free if you want. I have even got Learn Polish Now for a computer which I never use and you can have it too. I have loads of stuff, which I will never use again and will probably throw away.
Sounded robotic to me
Should be just up your street then!
