- 语音语言病理学 语言病理学
- 计算语言学计算语言学
- 儿科听力学 儿科听力学
背景情况:
- 语音音障碍 (SSD) 在儿童中很常见,造成沟通挑战.
- 由语音语言病理学家 (SLP) 进行的传统SSD评估是耗时的,可能缺乏可靠性.
- 开发自动化工具对于高效和一致的SSD评估至关重要.
研究的目的:
- 为了比较语音语言病理学家 (SLPs) 和自动语音识别 (ASR) 模型之间的语音声音障碍 (SSD) 评估结果.
- 评估在韩国的标准化SSD诊断工具上微调的ASR模型的性能.
- 确定ASR模型在评估儿童言语中的优点和局限性.
主要方法:
- 使用精心调整的 wav2vec 2.0 XLS-R 模型,在广泛的多语言成人语音数据上进行预训练,并进一步训练儿童发音错误的语音.
- 韩国对30名怀疑患有SSD的3至7岁儿童进行了两项标准化的评估,即儿童声学和口音评估 (APAC) 和口音和声学尿道测试 (U-TAP).
- 通过ASR生成的转录与SLP转录进行了仔细比较,以评估差异和相关性.
主要成果:
- 该ASR模型与SLP语音错误率有很好的相关性,APAC的类内相关系数为0.984,U-TAP的系数为0.978.
- 在ASR和SLP转录之间,语音错误率为APAC的8.42%和U-TAP的8.91%.

Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
