Software and hardware have been developed to create a powerful, inexpensive, compact digital signal processing system which in real-time extracts a low-bit rate linear predictive coding (LPC) speech system model. The model parameters derived include accurate spectral envelope, formant, pitch, and amplitude information. The system is based on the Texas Instruments TMS320 family, and the most compact realization requires only three chips (TMS320E17, A/D-D/A, op-amp), consuming a total of less than 0.5 W. The processor is part of programmable cochlear implant system under development by a multiuniversity Canadian team, but also has other applications in aids to the hearing handicapped.
已开发出软件和硬件，以创建一个功能强大、价格低廉、紧凑的数字信号处理系统，该系统能实时提取低比特率线性预测编码（LPC）语音系统模型。导出的模型参数包括精确的频谱包络、共振峰、音高和幅度信息。该系统基于德州仪器的TMS320系列，最紧凑的实现方式仅需三个芯片（TMS320E17、A/D - D/A、运算放大器），总功耗不到0.5瓦。该处理器是加拿大一个多大学团队正在开发的可编程人工耳蜗植入系统的一部分，但在听力障碍辅助设备中也有其他应用。
