Border areas were heavily influenced by the neighboring dialects, and so the original microdialects remained more or less intact and immigrants are in the process of assimilation.

Notable settlements include Kočevje, Šalka Vas, Livold, Mozelj, Podlesje, Kočevska Reka, Borovec pri Kočevski Reki, Grčarice, Koblarji, Stari Log, Črmošnjice, Planina, and Koprivnik.

[11] The first immigrants to come here were mostly from the Central Sava Valley and moved to this area a few years prior to the Second World War; therefore most of them spoke the Zagorje-Trbovlje subdialect.

[13] The only research on the microdialects spoken here was a bachelor's thesis that focuses on the Kočevje microdialect, and it appears to be very similar to standard Slovene with similarities to the Upper Carniolan dialect, such as no diphthongs, ukanye, the ending -u instead of -i in dative/locative singular o-stems, and very prominent vowel reduction, especially for the endings -o and -i.

[14] The dialect shows clear influence of the Ljubljana microdialect, and possibly also standard Slovene.

[13] The bachelor's thesis does not provide stress diacritics,[14] but when researching White Carniolan dialects Tine Logar mentioned that the accent shifts *məglȁ → *mə̀gla, *sěnȏ / *prosȏ → *sě̀no / *pròso, *visȍk → vìsok, and *kováč → *kòvač are not present "on the other side of the Kočevje forests"; that is, in the Mixed Kočevje subdialects, which would be reasonable because neither the Lower Carniolan nor Upper Carniolan dialects have undergone these accent shifts.

[17] The unified dialect shows typical features of colloquial speech, such as the short infinitive instead of long, the infinitive ending in -či now has the suffix -t, the locative singular has merged with the dative, pəsa instead of psa (final accent became fixed), and many masculine nouns became t-stems, but the dual and neuter gender still exist.
