has somewhat different allophones for and . Tine Logar also recorded the phoneme . Vowels In contrast to consonants, vowels differ significantly between the four microdialects, especially in accented syllables. They all have thoroughly researched accented vowels; however, Oseacco () lacks research on unaccented vowels. This is the accent system for San Giorno (): Evolution The evolution of Resian into such a distinct dialect happened gradually and in three stages. The first stage lasted until the 14th century; at that time, Resian was mostly influenced by the Gail Valley dialect. In the second stage, it acquired many features of Venetian Slovene dialects and other Littoral dialects. The third stage represents changes that are unique to Resian and cannot be found elsewhere. First stage Until the 13th century, Resian experienced the same evolution as all other Slovene dialects, forming into Alpine Slovene. It was part of the northwestern dialect because long yat diphthongized into *ie and long *ō diphthongized into *uo. It did not experience denasalization of nasal vowels. After further division, it fell into the category of the northern dialect, the same as other Carinthian dialects and unlike other Littoral dialects. It thus did not experience lengthening of non-final vowels at that time, because vowel lengthening in northern dialects happened only after the 16th century, well past the point when Resian lost contact with the Carinthian dialects and leading to possible different reflexes for formerly long and short vowels. Long *ə̄ also turned into *ē, which is unique to Resian in comparison to other Littoral dialects because there it turned into *a. The evolution then continued the same as with other Carinthian dialects, leading to the Carinthian dialect base. Short non-final *ě̀, *ò, and è evolved differently from their long counterparts, into *é, ó, and é, respectively. Long *ē turned into *ẹ̄, whereas the nasal vowels remained intact and only lengthened. Long *ə̄ turned into a very open ȩ̄ and short non-final vowels lengthened. Later, Resian followed the same patterns as the Jaun Valley dialect, such as *ie and *uo simplifying into *iə and *uə, *é and ó turned into *ẹ and *ọ, and the > accent shift, as well as the merger of *ē and *ě̄. Long nasal vowels also denasalized and *ę̄ merged with *ə̄, resulting in *ē and *ō. Second stage The second stage was primarily influenced by the Torre Valley dialect. Open *ē and *ō became
