- 端点检测是指用数字处理技术来找出语音信号中的各种段落（如音素、音节、词素、词等）的始点和终点的位置。语音段起止端点检测是语音分析、语音合成和语音识别中的一个必要环节。传统的端点检测方法是从wav文件中获取语音采样，将其分帧并计算短时能量和过零率参数，然后进行端点检测。这种工作方式被称为离线处理方法 ，无法实现语音信号的实时处理，对于语音信号分析具有一定的局限性。本文通过开发ActiveX控件，在MATLAB环境下将其嵌入到figure窗口中，以GUI程序的方式使用，实现语音信号端点检测的实时处

- 电烤箱作为一种重要的生产工具广泛的应用于工业生产和食品加工等领域。电烤箱的温度是生产工艺的一项重要指标，对温度的控制性能在很大程度上决定了产品的质量和生产效率。 系统以P89V51RD2单片机为核心，实现了温度采集、PID控制、人机对话以及定时等功能。由于干扰和实际噪声的存在，在采样过程当中会出现采样信号与实际信号存在偏差的现象，为了减小这方面原因造成的测量误差，系统采用了16次采样取平均值的方式对采样值进行平滑滤波，再对滤波值查表就得到了实际的温度值。在控制方面采用PID控制，温度控制具有
