This study aims to provide a linguistic analysis of the problem of recognizing Korean dialects in speech recognition, by examining the characteristics of dialects that cause errors in speech recognition experiments using dialectal speech data. To accomplish this, we classified dialectal features that differ from standard Korean into two categories: substitution and deletion. Our analysis of the results of speech recognition experiments revealed that dialectal features such as the merging of phonemes, substitution between vowels that are not discriminable in some environments, and omission of phonemes that only exist in dialects or are numerically infrequent, act as obstacles to speech recognition. We also describe how grammatical morphemes used in dialects that are homonymous with those in standard Korean or differences in pronunciation at the word level between dialects and standard Korean also lead to a significant number of recognition errors. This study sheds light on the challenges of recognizing Korean dialects in speech recognition and provides insights for developing more accurate and efficient speech recognition systems.
