技术领域technical field

本发明属于医疗实验用装置领域，涉及一种言语算法实验装置，尤其涉及一种人工耳蜗言语算法实验装置。The invention belongs to the field of medical experiment devices, and relates to a speech algorithm experiment device, in particular to a cochlear artificial speech algorithm experiment device.

背景技术Background technique

人工耳蜗是目前为止唯一可以使重度极重度感音神经性聋患者恢复听力及言语交流能力的听觉康复设备。其工作原理是通过一定的言语处理策略对声音信号进行处理，然后转换为电信号，刺激患者残存的听神经。人工耳蜗处理策略决定了言语辨识的效果。Cochlear implants are so far the only hearing rehabilitation equipment that can restore hearing and speech communication abilities to patients with severe to severe sensorineural deafness. Its working principle is to process the sound signal through a certain speech processing strategy, and then convert it into an electrical signal to stimulate the remaining auditory nerve of the patient. Cochlear implant processing strategies determine the effectiveness of speech recognition.

在研究人工耳蜗信号处理策略时，一般需要进行声学模拟，将模拟的声学信号播放给听力正常人或者轻中度感音神经性聋患者，评估某种处理策略处理后声音的辨识情况，从而评估信号处理策略的优劣。在声音信号处理策略中，关键步骤是提取声音信号的包络信息，并受很多参数影响。目前人工耳蜗声学模拟方面的研究仅局限于几个实验室，原因在于需要用matlab等软件编写程序代码，而对于非工科背景的临床医师及相关人员来说，虽然对人工耳蜗的效果评估非常感兴趣，但碍于无相关基础编写代码，严重阻碍了临床医师及相关人员参与人工耳蜗言语处理策略方面的研究。。When studying cochlear implant signal processing strategies, it is generally necessary to carry out acoustic simulation, play the simulated acoustic signals to normal hearing people or patients with mild to moderate sensorineural deafness, and evaluate the recognition of the sound processed by a certain processing strategy, so as to evaluate Pros and cons of signal processing strategies. In the sound signal processing strategy, the key step is to extract the envelope information of the sound signal, which is affected by many parameters. At present, the research on the acoustic simulation of cochlear implants is limited to a few laboratories. The reason is that the program codes need to be written with software such as matlab. For clinicians and related personnel with non-engineering backgrounds, although they are very interested in the evaluation of the effect of cochlear implants. However, due to the lack of relevant foundation to write codes, clinicians and related personnel are seriously hindered from participating in the research of cochlear implant speech processing strategies. .
