1、本科毕业设计(20届)基于语音辨识自动数学出题系统--系统功能控制摘要单片机技术日渐成熟,由于它体积小,能耗低,性价比高的特点,其应用范围也日渐广泛,诸如生产设备的控制,高端电子设备处理芯片,日常生活用品的一些简单面板控制等等都与单片机相关。近年来,随着我国国民素质的不断提高,家长们越来越重视孩子的教育问题。本出题系统适用于少年儿童进行算术训练来提高他们的计算能力。当然,在此基础上,通过丰富出题方式,改进考核模式,激发孩子们的学习积极性,提高他们的反应力及心算的能力。对于孩子们来说,出题器更应该是一个玩具而不是一个加重他们负担的学习工具。因此,它应该具有友好的界面和游戏般的测
2、试模式,让孩子们开开心心地学习。这才是出题器应有的作用。虽然不可能超越高端电子产品,但是至少也能体现它应有的价值。本系统能根据用户的不同设置给出不同级别、不同运算法则的算术题,同时进行语音播报,待用户输入答案,并按下确定键之后,系统对答案进行纠错,播报相应的语音,而且系统还提供了显示答案的功能,另外,本系统还集成了语音识别模块,用户可以通过设定相应操作的语音命令,然后通过语音命令来进行部分功能操作。关键词:SPCE061A单片机;语音识别;语音播报AbstractMicroprogrammedControlUnit(MCU)technologymatures,becausei
