I was hoping someone would be able to advise me on how to sing this word; 'srdéčko'. My problem lies with the two first letters, 'sr' because they seems to be a sylable on they're own but i don't know what vowel to sing to it.
There's something sounding slightly like an e inbetween s and r: serdéčko Linguists call this "semi-vowel", I think. You can find this in (UK) English also, for instance at the end of words that end with "er", like... disaster...
it's not schwa, not sure about semi-vowel (dunno what it exactly means) "r" in czech is rolled so it effectively works as a vowel
There is no such thing as a semi-vowel. Either your hear a vowel or a consonant. For example [w] is a consonant, but is a vowel. As regards the /r/ in the word mentioned, if you forget the spelling, close your eyes, and listen carefully, you'll perceive a schwa, and you'll even see where it is placed in the syllable.
