 In Serbo-Croatian and Slovenian, double grave accent is used to indicate a short falling tone, though in discussion of Slovenian, a single grave accent is also often used for this purpose.The double grave accent is found in both Latin and Cyrillic; however, it is not used in the everyday orthography of either language, only in discussions of the phonology of these languages.In the International Phonetic Alphabet, the double grave accent is used to indicate extra-low tone.
