This paper describes the Velotrace, a mechanical device designed to allow the collection of analog data on velar position. The device consists of two levers connected through a push rod and carried on a pair of thin supports rods. The device is positioned in the nasal passage with the internal lever resting on the nasal surface of the velum and the external lever positioned outside the nose. The movements of the external lever reflect the movement of the internal lever as it follows velar movement and are recorded as an analog signal using an optoelectronic position-sensing system. Results of evaluation studies indicate that the Velotrace accurately reflects the relatively rapid movements of the velum during speech.
本文介绍了软腭运动轨迹追踪仪，这是一种用于收集软腭位置模拟数据的机械设备。该设备由通过推杆连接的两个杠杆组成，并由一对细支撑杆支撑。该设备放置在鼻腔通道中，内部杠杆靠在软腭的鼻表面上，外部杠杆位于鼻子外部。当内部杠杆跟随软腭运动时，外部杠杆的运动反映了内部杠杆的运动，并使用光电位置传感系统记录为模拟信号。评估研究结果表明，软腭运动轨迹追踪仪能准确反映言语过程中软腭相对快速的运动。
