幅度估计 (ME) 显示在评估儿科语音质量方面具有很高的可靠性,在某些情况下超过视觉排序和排名 (VSR) 和共识听觉感知语音评估 (CAPE-V). 这表明ME可能会改善儿童的临床语音评估.
科学领域:
- 语音语言病理学 语言病理学
- 声学分析 声学分析
- 声音障碍 声音障碍
背景情况:
- 声音的共识听觉感知评估 (CAPE-V) 是语音评估的标准工具,但它对儿科声音的可靠性,特别是上声源 (SGVS),是可变的.
- 基于实验室的方法,如视觉排序和排名 (VSR) 和大小估计 (ME),为感知语音质量评估提供了替代方法.
研究的目的:
- 为了比较CAPE-V,VSR和ME方法的可靠性,以评估儿科失声声音中的呼吸,粗和紧张的声音品质.
- 调查这些方法在不同语音源 (SGVS和喉振动源/GVS) 的可靠性.
主要方法:
- 分析了来自4至11岁儿童的124个语音样本.
- 三名专家听众使用VSR,ME和CAPE-V评估了呼吸难度,粗度和应变.
- VSR涉及分类和排名语音样本;ME涉及分配一个大小得分 (1-1000).
主要成果:
- 这三种方法都表现出高的评审者内部和评审者间可靠性.
- 大小估计 (ME) 在所有语音品质和来源中显示出最高的内定值可靠性.
- 对于SGVS样品来说,ME的可靠性更高,而对于GVS样品来说,VSR更可靠.
- 在这三种评估方法之间发现了强烈的相关性.
结论:
- 在这项受控研究中,专家临床医生对CAPE-V,VSR和ME的可靠性相似.
- 在SGVS和GVS之间注意到可靠性的轻微差异.
- ME任务的比率级扩展可能会提高更广泛的临床应用的可靠性,可能有助于经验较少的听众.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
