The paper investigates generational differences in the phonology of Mala Rakovica speech. The speakers are divided into three generations: young, middle and old. The aim of the research is to see if there are any differences between their speech and to what extent. It used the method of recording spontaneous speech, which was later transcribed in order to more easily make the desired comparisons of vocalism, consonantism and, to a lesser extent, prosody with Kajkavian and standard language. The experiment also included an experiment with several students of phonetics at the Faculty of Philosophy in Zagreb, and the results were subjected to acoustic analysis. By comparing these results with the acoustic values of standard vocals, deviations were observed, which proved the difference between standard vocals and the vocals of Kajkavian speech in Mala Rakovica. The study confirmed the initial thesis that most of the Kajkavian characteristics of vocalism, consonantism and prosody in speech are retained by speakers of the older generation, slightly less by speakers of the middle generation, and the least by the young, with the least deviations from the standard. The paper also contains a methodical component describing work with a 12-year-old girl from Mala Rakovica, with whom was worked the phonetic pronunciation correction of voice /o/. The closed pronunciation of that voice, which is characteristic of the spoken speech, tried to switch to the standard, middle pronunciation by the verbotonal method. This method proved to be successful and the desired corrective voice pronunciation was obtained.
