摘要
给出了一种由说话者说出控制命令,机器人进行识别理解,并执行相应动作的实现技术。在此,提出了一种高准确率端点检测算法、高精度定点DSP动态指数定标算法,以解决定点DSP实现连续隐马尔科夫模型CHMM识别算法时所涉及的大量浮点小数运算问题,提高了定点DSP实现的实时性、精度,及其识别率。
In the 21st century,intelligent robot will be more and more used in every-day life.In this paper,a robot control method is presented via voice spoken by a speaker naturally.When speakers spoke commands,robot would recognize them and implement corresponding action.A new advanced voice section detection method and dynamic exponential scalar algorithm which is used to realize CHMM on fix-point DSP is given in this paper.These two methods improved robot＇s reality,and advanced its recognition accuracy.
