The final purpose of this study is to integrate oral data into a single corpus, targeting the Jeonbuk dialect, and to use it. Spoken materials, dialect materials, and large-scale corpus are indispensable for complete language study. To this end, the existing dialect oral data collected shall be integrated and made into a corpus. This may be better than collecting new data. This paper aims to target the Jeonbuk dialects, and to form an oral corpus. At this time, I would like to make grammar study as the primary purpose. To this end, the current situation of the oral speech materials in Jeonbuk dialects that have been collected so far is summarized and major issues were discussed. In particular, it was argued that corpus needs to be integrated through: morphophoneme transcription and morphological analysis, spacing and eojeol analysis, segmentation based on sentence.
