10%的学龄前和学龄儿童患有语音障碍，对他们的交流、学习成绩和互动水平产生不利影响。有效的发音训练需要长时间的有监督的练习和互动。不幸的是，许多孩子没有机会或只有有限的机会接触语言病理学家。计算机辅助发音训练有可能成为一种非常有效的教学辅助工具；然而，到目前为止，这种系统仍然无法以足够的准确性识别发音错误。在本文中，我们建议通过(1)从大型儿童语音数据库中学习声学模型，(2)使用目标年龄范围内儿童典型发音错误的显式模型，以及(3)对扭曲音素的声学进行显式建模来提高准确性。
Phonological disorders affect 10% of preschool and school-age children, adversely affecting their communication, academic performance, and interaction level. Effective pronunciation training requires prolonged supervised practice and interaction. Unfortunately, many children do not have access or only limited access to a speech-language pathologist. Computer-assisted pronunciation training has the potential for being a highly effective teaching aid; however, to-date such systems remain incapable of identifying pronunciation errors with sufficient accuracy. In this paper, we propose to improve accuracy by (1) learning acoustic models from a large children's speech database, (2) using an explicit model of typical pronunciation errors of children in the target age range, and (3) explicit modeling of the acoustics of distorted phonemes.
