概括
一种新方法,即语音的自动时间分析 (ATAS),通过分析停顿和声音事件,准确地测量语音流性. 这种工具有助于诊断口吃,可以区分口吃的成年人和不口吃的成年人.
科学领域:
- 语音语言病理学 语言病理学
- 计算语言学计算语言学
- 生物医学工程 生物医学工程
背景情况:
- 流利性障碍,就像发育性口吃一样,涉及诸如阻塞,重复和延长之类的语言流利性障碍.
- 准确测量口吃行为对于诊断和有效的治疗计划至关重要.
- 当前的评估方法可以从补充的客观措施中受益.
研究的目的:
- 引入和验证用于评估语音流性的自动时间语音分析 (ATAS) 方法.
- 使用ATAS量化语音时间事件,包括停顿和发音,使用ATAS.
- 评估ATAS指标与口吃严重程度的相关性,以及根据口吃状态对个人进行分类的能力.
主要方法:
- 开发了ATAS管道,以检测和量化口语阅读音频样本中的离散暂停和声音事件.
- 收集了35名英语参与者的语音数据,17名成年人口吃 (AWS) 和18名成年人不口吃 (AWNS).
- 利用机器学习分类器 (随机森林,LSTM) 来根据ATAS指标预测参与者群体状态.
主要成果:
- 与没有口吃 (AWNS) 的成年人相比,口吃 (AWS) 的成年人表现出显著更多的暂停 (语音速度较慢,总暂停时间较长,暂停数较多,平均暂停时间较长).
- ATAS衍生的暂停和语音指标与口吃的音节百分比有很强的相关性,这是口吃频率的标准衡量标准.
- ATAS指标能够准确地将参与者分为AWS和AWNS组,超过随机猜测的准确性.
结论:
- ATAS方法提供了客观的,可量化的时间语音指标,与公开口吃行为高度相关.
- ATAS为语音语言病理学家提供了一个有希望的替代和补充工具,用于评估流性障碍.
- 语音时间的自动化分析对改善口吃的诊断和管理具有重大潜力.

00:55Convenience Sampling Method
8.6K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:15Heart Sounds
3.7K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

01:26Assessment of the Mouth
1.6K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
