电子耳蜗言语训练及发音模拟系统

听力障碍患者可根据听力障碍程度选择佩戴助听器或植入电子耳蜗，其中重度耳聋患者需要植入电子耳蜗以恢复听力感知能力。电子耳蜗手术植入后，患者仍需要大量的言语康复训练，以适应电子耳蜗和日常言语交流。目前，训练的主要方式是人工训练，不利于提高听力康复训练的效率。本研究开发了一套基于电子耳蜗常用言语处理策略的言语训练及发音模拟系统。该系统可用于语音信号的采集，并进一步将采集到的信号转换成特定的言语处理策略。它可以帮助医生对患者进行听力训练，也可以用于开发新的言语处理策略和算法评估，该系统采集和合成的康复训练信号能准确地反映电子耳蜗言语处理策略的特点，GUI界面简单易用，便于在临床推广应用。

Speech training and pronunciation simulation system for cochlear implant

Patients with hearing impairment can choose to wear hearing aids or have cochlear implantation according to the degree of hearing impairment,and those with severe deafness need cochlear implant to restore their ability of hearing perception.After cochlear implantation,patients still need a lot of speech rehabilitation training to adapt to cochlear implant and daily speech communication.At present,the main training method is artificial training which is not conducive to improving the efficiency of hearing rehabilitation training.Therefore,a speech training and pronunciation simulation system based on common speech processing strategies of cochlear implant is developed.The system which can be used to collect speech signals and further convert the collected signals into specific speech processing strategies can help doctors to carry out hearing training for patients and can be used to develop new speech processing strategies and algorithm evaluations.The rehabilitation training signals acquired and synthesized by the system can accurately reflect the characteristics of speech processing strategies of cochlear implant.Moreover,the GUI interface is simple and easy to use,which is benefit for clinical application.
