概括

本教程介绍了模拟舌头轮的两种方法:多变量通用添加模型 (MGAM) 和多变量功能主要组件分析 (MFPCA). 建议研究人员使用MFPCA进行初始舌头轮建模,因为它比MGAM具有优势.

科学领域:

语言学的语言学.
计算语言学计算语言学
语音科学语言科学

背景情况:

准确地建模舌头发音对于理解语音的产生至关重要.
DeepLabCut是一个强大的工具,用于跟踪动物的姿势,适应生物力学分析,如舌头运动.
分析复杂的关节数据的现有方法可能是有限的.

研究的目的:

介绍和比较两个语言轮数据的统计建模方法.
提供一个实用的指南和可复制的代码来分析表达式语音数据.
为初始舌头轮建模推最有效的方法.

主要方法:

使用多变量通用添加模型 (MGAMs) 建模舌头轮数据.
使用多变量功能主要组件分析 (MFPCA) 建模舌头轮数据.
分析了两个数据集:意大利/波兰的VC配音和黎巴嫩阿拉伯音强调度,使用DeepLabCut生成的数据.

主要成果:

无论是MGAM还是MFPCA都可以模拟舌头轮数据.
与MGAM相比,MFPCA被认为是模拟舌头轮的更有利的初始方法.
该研究提供了可访问的数据和评论代码,用于复制和进一步研究.

结论:

建议使用MFPCA而不是MGAM作为建模舌头轮的首选第一步.
该教程有助于将先进的统计建模应用到发音声学中.
语音科学中的可重复性研究通过共享汇编得到支持.

Assessment of the Mouth

Assessment of the Mouth

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.

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

The Tongue and Taste Buds

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...
