Functional-morphological relationships in functional articulation disorders

The dataset was used for the needs of a study of functional-morphological relationships described in the paper: 'Functional-morphological relationships in functional articulation disorders'. Among others, the study was based on preliminary results obtained with AFDA INIA: a custom-made non-invasive device for the analysis of the acoustic field distribution around the speaker’s face. We presented a case study that visualises the AFDA INIA results. Our findings contribute to the assumption that the orofacial system represents a functional–morphological set, forming a functional whole influenced also by body symmetry and cranial positioning. The experimental case study demonstrates AFDA INIA as a tool that could be useful for larger scale studies involving both detailed phonetic-acoustic analyses and diagnostic procedures in clinical settings.The video material included in the INIA.mp4 file documents a prototype system named AFDA INIA (the AFDA acronym comes from the Acoustic Field Distribution Analyzer while INIA stands for the Integrated Non-Invasive Analyzer). The INIA acronym also refers to the name of the so-called Amazonian river dolphin characterized by a very well-developed sense of spatial hearing. The prototype system consists of the INIA Array device and the INIA Fusion application. Audio data acquisition is carried out using the INIA Array device, including a circular microphone array. 16 microphones based on MEMS (Micro-Electro-Mechanical Systems) technology were used. The microphones feature integrated PDM (Pulse Density Modulation) signal modulators. An additional element of the device is a laser multi-zone distance sensor using the ToF (Time of Flight) technique. The use of a distance sensor enables focusing of the acoustic beam precisely on the surface of the examined person's face which is essential due to the need of compensating for face shape differences and the inevitable slight movement of the head during the examination. The sensor laser meets the requirements of class 1 (Norm PN- EN 60825-1:2014) and is therefore safe for human vision. Audio data and 3D images from the distance sensor are sent to the INIA Fusion application using the USB interface.本数据集用于支撑一篇题为《功能性构音障碍中的功能形态关系》的研究论文。该项研究的基础数据之一，为通过AFDA INIA获取的初步测试结果——AFDA INIA是一款定制化非侵入式设备，用于分析发声者面部周围的声场分布。本研究还呈现了一则可视化AFDA INIA测试结果的案例分析，其研究结果支持如下假设：口面部系统属于功能形态集合，构成一个同时受身体对称性与颅骨位置影响的功能整体。本次实验案例研究证实，AFDA INIA可作为一款实用工具，适用于涵盖精细语音声学分析与临床诊断流程的大规模研究。INIA.mp4文件内的视频素材，记录了一款名为AFDA INIA的原型系统（其中AFDA为Acoustic Field Distribution Analyzer（声场分布分析仪）的缩写，INIA为Integrated Non-Invasive Analyzer（集成式非侵入分析仪）的缩写）。此外，INIA这一缩写同时指代一种拥有优异空间听觉感知能力的亚马逊河豚。该原型系统由INIA Array设备与INIA Fusion应用程序组成。音频数据采集通过INIA Array设备完成，该设备搭载环形麦克风阵列。本次研究采用了16台基于MEMS（Micro-Electro-Mechanical Systems，微机电系统）技术的麦克风，其内置PDM（Pulse Density Modulation，脉冲密度调制）信号调制器。该设备还配备了采用ToF（Time of Flight，飞行时间）技术的激光多区域距离传感器。借助该距离传感器，可将声学波束精准聚焦于受检者面部表面——这对于补偿面部形态差异、抵消检测过程中头部不可避免的轻微移动至关重要。该激光传感器符合Class 1级安全标准（符合PN-EN 60825-1:2014规范），对人体视觉无安全风险。音频数据与距离传感器采集的三维图像通过USB接口传输至INIA Fusion应用程序。
