[4][5] The area where the Lower Carniolan dialect is spoken spans from the Javornik Hills and Snežnik Plateau in the west to Orehovec, Škocjan, and Polšnik in the east, and to the Sava River and Ljubljana Marsh in the north.

Notable settlements include Cerknica, Stari Trg pri Ložu, Sodražica, Ribnica, Velike Lašče, Borovnica, Ig, Škofljica, Grosuplje, Turjak, Šmartno pri Litiji, Ivančna Gorica, Žužemberk, Dolenjske Toplice, Novo Mesto, Mirna Peč, Mirna, Šentrupert, Mokronog, Trebelno, Škocjan, Šmarješke Toplice, and Šentjernej.

It has also retained pitch accent and has relatively well-preserved quantitative differences between long and short syllables.

In other parts, the acute starts to turn into a circumflex accent, but this is mostly limited to specific endings.

In the dialect, change also occurs outside of endings, and in the south, around Novo Mesto, it has generally turned into a circumflex.

Non-final *ě̀ and *ě̄ are the diphthong ēi̯, which turned into āi̯ in the southwestern and southern part and might have monophthongized into ē or ǟ elsewhere, particularly in the northeast.

Newly stressed *e and *o mostly diphthongized into ēi̯ and ōu̯ in the east and west, but changes differently in the central area.

Yat (*ě̄) monophthongized, *ī and *ū widened or diphthongized, and there is a higher degree of vowel reduction.
