资料介绍

研究利用人类语音相关特征参数会随人类情绪波动的特点,设计一种能够通过语音识别进行语音情感计算,从而分析出人的情绪变化的电路。根据语速变化时汉字的浊音部分基音频率也会发生变化,且浊音部分语音具有基音周期的特点,综合设计出能根据语音信息进行情感计算的硬件电路系统。设计过程中利用Matlab处理与分析语音信号,使用Multisim进行电路的仿真。电路充分考虑了信号处理各个模块的鲁棒性,能有效捕捉、判断人的情绪状态并通过报警装置进行情绪提醒,为后续医学信息相关实验的开展提供了硬件基础。

By taking advantage of the characteristic that human speech related feature parameters can fluctuate with human emotions,a circuit that can calculate speech emotion by speech recognition to analyze human emotion changes is designed.Ac cording to the characteristic that the pitch frequency in the voiced sound part of Chinese characters changes with the variation of speech speed and the voiced sound part has pitch period,a hardware circuit system that can make affective computation accord ing to speech information is designed synthetically.In the design process,Matlab is used to process and analyze the voice sig nal,and Multisim is used to simulate the circuit.The circuit designed in this paper fully considers the robustness of each mod ule for signal processing,which can effectively capture and judge the people′s emotional state and give emotional reminders by the warning device,so as to provide the hardware basis for the follow up experiments related to medical information.
