概括
用麦克风和部加速度计测量的声音声学参数显示出强烈的一致性,这表明加速度计可以在各种环境中进行语音分析. 这增强了对临床评估语音指标的信心.
科学领域:
- 语言科学
- 生物医学工程
- 听力学
背景情况:
- 准确的声音声学参数测量对于临床声音评估至关重要.
- 传统的方法依赖于麦克风,但加速度计在控制较少的环境中具有使用潜力.
研究的目的:
- 评估来自麦克风和部加速度计的声音声学参数之间的一致性.
- 研究录制时刻和语音类型对这些参数的影响.
主要方法:
- 对单个患者进行了为期7周的同时记录研究,以尽量减少患者间的变异性.
- 使用布兰德-阿尔特曼图表进行了评估,并使用通用估计方程分析了关联.
主要成果:
- 在麦克风 (MIC) 和加速度计 (ACC) 测量中没有发现关键参数如α比率,CPP,PPE,SPL SD以及基本频率 (fo) 平均值和SD的显著偏差.
- 语音类型和录制时间显著影响了阿尔法比,而不是测量仪器.
- 与加速度计相比,麦克风测量显示CPP和FOSD略低,而阅读任务则显示CPP和FOSD高于母音.
结论:
- 基本频率,阿尔法比率,PPE和SPL SD在两个测量仪器中都是强大的.
- 子加速度计显示在控制较少的环境中具有语音分析的潜力.
- 这些发现支持对语音指标的信任度增加以及开发高效的临床评估方案.

02:01Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Respiratory Depth
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:
