| 摘 要： | 为增加大型系统数据输入方式的多样化和灵活性,提出一种基于片上可编程系统(System On Programmable Chip,SOPC)的语音-文本转化方法。通过采用SOPC软硬协同设计实现基于线性预测编码(Linear Predictive Coding,LPC)算法的语音信号处理。与其他现有的实现方式比较,该方法可大大节约系统硬件资源,具有更优的处理性能,适用于大型系统用户数据输入源。

| Abstract: | In order to improve the diversity and the flexibility of input methods in a large digital system,a technique of speech-to-text transforming is proposed based on SOPC(System On Programmable Chip).With SOPC hardware and software co-designing method,the LPC(Linear Predictive Coding) algorithm for speech signal processing is set up.Compared with others,using this technique can save more hardware resources. |
