It includes the speech of local people. We employed the listening and speaking method. The listening method was equipped with note taking and tapping techniques, while the speaking method was equipped with by probing, face-to-face, and recording techniques. The techniques to analyze our data included reciprocal understanding, dialectometry, permutation and isogloss file. Based on our analysis, we find that the isolect status is based on different vocabularies, speeches, subdialects and dialects. This shows that the language diversity in the typical isolect still exists. These findings also prove that the Yogyakarta and Surakarta dialect holds isolect diversity as a representation and evidence of language diversity.
