本程序包含语音压缩和语音识别领域所需的LPCC，MFCC特征提取算法以及语音端点检测源码。在对语音数据进行特征提取前，可对语音数据进行16K到8K的降采样率处理，包含180阶FIR滤波器的频率压缩程序 -This procedure includes voice compression and voice recognition requirements in the area of the LPCC, MFCC feature extraction algorithm, as well as voice activity detection source. Voice data in the feature extraction before the voice data can be 16K to 8K sampling rate of the drop treatment, including the 180-order FIR filter frequency compression procedures

为锁相回路或锁相环，用来统一整合时脉讯号，使内存能正确的存取资料。PLL用于振荡器中的反馈技术。 许多电子设备要正常工作，通常需要外部的输入信号与内部的振荡信号同步，利 用锁相环路就可以实现这个目的。(For phase lock loop or phase lock loop, the unification and the integration of the pulse signal used to when, make memory can correct access material. The technology used in PLL oscillator feedback. Many electronic equipment to be normal work, usually need to external input signal and internal oscillation signal synchronization, with the phase lock loop can achieve this goal.)

说明：  基于卡尔曼滤波的IMMF算法，运用了CA和CV模型，得到了目标跟踪图像和误差(IMMF algorithm based on Kalman filter, using CA and CV model, obtains target tracking image and error.)

基于matlab的男女生辨别系统，根据基音频率进行辨别，在安静环境内，识别度较高(Matlab-based male and female discrimination system, based on the pitch frequency to identify, in a quiet environment, the recognition degree is higher)

delphi mqtt通讯。没有用到第三方的控件。可以在delphi7编译通过。(Delphi mqtt communication. No third-party controls are used. It can be compiled and passed in Delphi 7.)

说明：  对comsol的初步了解和学习是有很大的帮助的，建议大家参考！(Comsol's initial understanding and learning is a great help, it is recommended that you reference!)
