A microprocessor-based real-time digital vibrotactile vocoder system has been developed to train the deaf and for artificial hearing research. The system is composed of a microcomputer module with a digital signal processor, interface units and an attenuator/driver circuit. Live or digitised (stored or synthetic) speech is presented to the skin spectrally through a belt housing eight or 16 vibrators. Speech is processed in real time using a fast Fourier transform. The system is also capable of presenting any arbitrary spatiotemporal pattern on the skin for artificial hearing experiments. A preliminary experiment with a deaf subject indicates that the system is potentially an effective device for artificial hearing.
一种基于微处理器的实时数字振动触觉声码器系统已被开发出来，用于训练聋人和进行人工听觉研究。该系统由一个带有数字信号处理器的微型计算机模块、接口单元和一个衰减器/驱动电路组成。实时或数字化（存储或合成）的语音通过一个装有八个或十六个振动器的腰带以频谱方式呈现给皮肤。使用快速傅里叶变换对语音进行实时处理。该系统还能够在皮肤上呈现任何任意的时空模式，用于人工听觉实验。对一名聋人受试者进行的初步实验表明，该系统可能是一种有效的人工听觉设备。
