摘要

针对国际中文教育中缺乏公开、标准化细粒度的汉语语音偏误数据集及通用模型非母语发音诊断适配有限的问题，构建面向留学生的汉语语音偏误数据集。采用融合基础声学对齐与专家诊断的十层结构化标注规范，建立“机器预标注—人工精修—专家复核”的人机协同流程，并完成数据清洗、质量复核与结构化入库，以保证样本可追溯和可训练。结果获得340份真实发音样本、12万余条声韵级时间对齐切片和数万条偏误诊断标签；在非母语口音自动语音识别和端到端语音偏误诊断任务中，基于该数据集微调的Paraformer-large与Qwen2-Audio-7B均表现出更好的任务适配效果。该数据集可为国际中文教育场景下的模型微调与智能发音反馈提供监督数据，也为垂直领域高质量数据集建设提供数据治理参考。

Abstract

To address the lack of open and standardized fine-grained pronunciation error datasets for international Chinese language education and the limited adaptation of general models to non-native pronunciation diagnosis

a Chinese pronunciation error dataset for international students was constructed. A ten-layer structured annotation scheme was developed by integrating basic acoustic alignment with expert diagnostic labels

and a human-machine collaborative workflow of machine pre-annotation

manual refinement

and expert review was established. Data cleaning

quality review

and structured storage were also completed to ensure that the samples were traceable and trainable. As a result

340 authentic speech samples

more than 120

000 time-aligned slices at the initial-final level

and tens of thousands of fine-grained diagnostic labels were obtained. To evaluate the dataset

two representative tasks were conducted: automatic speech recognition for non-native accented speech and end-to-end pronunciation error diagnosis. The results showed that

after fine-tuning on the dataset

Paraformer-large and Qwen2-Audio-7B achieved better task adaptation. The dataset provides supervised data for model fine-tuning and intelligent pronunciation feedback in international Chinese language education

and it also offers a reference for high-quality dataset governance in vertical domains.
