概括
语音病理学家 (SLP) 对儿童语音可理解性的主观估计不是准确或可靠的测量. 这项研究发现,SLP和天真听众的主观评分与基于转录的评分有显著差异.
科学领域:
- 语音语言病理学 语言病理学
- 儿童语言习得 儿童语言习得
- 听觉感知是一种听觉感知.
背景情况:
- 准确评估语音可理解性对于有效干预语言障碍儿童至关重要.
- 主观可理解性估计通常使用,但与客观测量相比,它们的可靠性和准确性尚未完全理解.
- 了解听者的感知,包括语音语言病理学家 (SLP) 和天真听者的感知,对于开发强大的评估工具至关重要.
研究的目的:
- 为了比较SLP和幼儿语音的天真听众提供的主观可理解性估计的准确性和可靠性.
- 调查语音障碍严重程度对SLP可理解性估计的影响.
- 评估不同听众之间的可理解度评分的一致性.
主要方法:
- 来自6名患有语言障碍的学前儿童的言语样本被18名认证的SLP和18名天真的听众评价.
- 听众使用了两种方法:拼写转录和主观百分比估计理解的单词.
- 准确性是通过估计和转录得分之间的绝对差异来评估的;可靠性是使用类内相关性来评估的.
主要成果:
- 语音服务提供者的主观估计偏离了转录分数的12.4%,而天真的听众则偏离了18.9%.
- 估计可理解性的interrater可靠性在两组中都比转录可理解性要低得多.
- 儿童言语障碍的严重程度并没有被详细描述为影响本摘要结果的因素.
结论:
- SLP对主观可理解性的估计不是足够准确或可靠来衡量儿童的语音可理解性.
- 正写转录似乎是一个更可靠的方法来评估语音可理解性.
- 需要进一步的研究来完善客观和可靠的方法来评估儿科语音障碍的可理解性.

Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

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...
