Description
Translated fromChinese技术领域technical field
本申请涉及可穿戴设备技术领域，特别是涉及一种辅助无声发音贴片和设备。The present application relates to the technical field of wearable devices, and in particular, to an auxiliary silent pronunciation patch and device.
背景技术Background technique
表面肌电信号(surface electromyography，sEMG)是肌肉收缩时伴随的电信号。研究表明，肌肉关节内的肌电信号存在着相应的语音信息，在发音时面部的肌肉呈现出不同的形态，于是可以输出不同的表面肌电信号，因此，分析处理表面肌电信号对帮助发音困难的患者进行沟通交流，以及患者的身心康复与治疗有着直接而深远的影响。Surface electromyography (sEMG) is an electrical signal accompanying muscle contraction. Studies have shown that there is corresponding voice information in the EMG signals in muscle joints, and the muscles of the face show different shapes during pronunciation, so different surface EMG signals can be output. Therefore, analyzing and processing surface EMG signals can help pronunciation. Difficulty communicating with patients, as well as their physical and mental recovery and treatment has a direct and far-reaching impact.
目前，辅助患者无声发音需要依靠柔性电极贴片和与柔性电极贴片相连的外部信号处理设备，将表面肌电信号转换为可识别的语音信号。柔性电极贴片贴在患者下颚皮肤处，对患者在无声发音时二腹肌前肌的表面肌电信号进行采集，然后将采集到的表面肌电信号传输至外部信号处理设备，由外部信号处理设备对表面肌电信号进行分析处理，得到与声音对应的信号。外部信号处理设备体积较大，较笨重，不利于表面肌电信号的实时测量，且于柔性电极贴片与外部信号处理设备之间需要连接许多导线，使用起来比较麻烦。At present, to assist patients with voiceless speech, they need to rely on flexible electrode patches and external signal processing equipment connected to the flexible electrode patches to convert surface EMG signals into recognizable speech signals. The flexible electrode patch is attached to the skin of the patient's lower jaw to collect the surface EMG signal of the digastric anterior muscle of the patient when the patient is silently articulating, and then transmit the collected surface EMG signal to the external signal processing equipment, which is processed by the external signal. The equipment analyzes and processes the surface EMG signal to obtain a signal corresponding to the sound. The external signal processing equipment is bulky and bulky, which is not conducive to the real-time measurement of surface EMG signals, and many wires need to be connected between the flexible electrode patch and the external signal processing equipment, which is cumbersome to use.
因此，如何解决上述技术问题应是本领域技术人员重点关注的。Therefore, how to solve the above technical problems should be the focus of those skilled in the art.
