한국인 표준 음성 DB 구축

Abstract

The data accumulated in this database will be used to develop a speaker identification system. This may also be appliedtowards, but not limited to, fields of phonetic studies, sociolinguistics, and language pathology. We plan to supplement thelarge-scale speech corpus next year, in terms of research methodology and content, to better answer the needs of diversefields. The purpose of this study is to develop a speech corpus for standard Korean speech. For the samples to viablyrepresent the state of spoken Korean, demographic factors were considered to modulate a balanced spread of age, gender, anddialects. Nine separate regional dialects were categorized, and five age groups were established from individuals in their 20sto 60s. A speech-sample collection protocol was developed for the purpose of this study where each speaker performs fivetasks: two reading tasks, two semi-spontaneous speech tasks, and one spontaneous speech task. This particular configurationof sample data collection accommodates gathering of rich and well-balanced speech-samples across various speech types, andis expected to improve the utility of the speech corpus developed in this study. Samples from 639 individuals were collectedusing the protocol. Speech samples were collected also from other sources, for a combined total of samples from 1,012individuals.
