An experimental system for a tactile hearing aid using a digital signal processor (DSP) is being developed. This system can be used to test and evaluate not only the familiar techniques for a tactile hearing aid, such as energy level display, filterbank analysis, etc., but also novel techniques. The system is being developed especially to try out new recognition strategies, because the currently available strategies are not satisfactory. A portable tactile hearing aid that can recognize certain environmental sounds (alarm sounds) and certain features from the speech signal (such as pitch, voiced/voiceless, or even complete phonemes), being a good support for lipreading, should be the final result of the experiments.
一种使用数字信号处理器（DSP）的触觉助听器实验系统正在研发中。该系统不仅可用于测试和评估触觉助听器的常见技术，如能量水平显示、滤波器组分析等，还可用于测试和评估新技术。该系统的研发尤其旨在尝试新的识别策略，因为目前可用的策略并不令人满意。实验的最终成果应是一款便携式触觉助听器，它能够识别特定环境声音（警报声）以及语音信号中的某些特征（如音高、浊音/清音，甚至完整音素），从而为唇读提供有力支持。
