LATIC: A Non-native Pre-labelled Mandarin Chinese Validation Corpus for Automatic Speech Scoring and Evaluation Task

LATIC is focusing on non-native Mandarin Chinese learners. It is an annotated non-native speech database for Chinese, which is fully open-source can get online for any purpose use. The related using area can be automatic speech scoring, evaluation, derivation—L2 teaching, Education of Chinese as Foreign Language, etc. We are aiming to provide a relatively small-scale and highly efficient training deviation dataset. For this target, four chosen non-native Chinese speaker participated in this project, and their mother tongue (L1s) varies from Russian, Korean, French and Arabic. It outputs a 1-hour testing audio file (valid recording) for each tester, which has 4 hours of materials. We intend to expand the scale of our current database continuously in the future as well.LATIC 聚焦于普通话非母语学习者。该数据集是一套经标注的汉语非母语语音数据库，完全开源且可在线获取，适用于各类用途。其相关应用领域包括自动语音评分、语音评估、衍生应用——第二语言教学、对外汉语教学等。本数据集旨在提供一套规模适中且高效的发音偏差训练数据集。为此，本项目招募了四名经遴选的普通话非母语发音者，其母语（第一语言，L1）分别为俄语、韩语、法语与阿拉伯语。每名测试参与者均可获取1小时的有效测试录音音频文件，整套数据集总素材时长共计4小时。我们亦计划在未来持续扩充该数据库的现有规模。
