语音识别机器人设计
【摘 要】 语音识别可划分为训练和识别两个过程。在第一阶段，语音识别系统对人类语言进行学习，把学习内容组成语音库存放起来，在第二阶段就能够把目前输入语音在语音库中查找对应词义或语义
。凌阳16位SPCE061A单片机内嵌32K字闪存，2K字SRAM，内置10位ADC、DAC,有多达14个中止源。它CPU内核采取16位含有DSP功效微处理器芯片, 而且CPU可最高工作在49MHz主频下，能够很轻易地、快速地处理复杂数字信号，所以和其它类型单片机相比，在数字语音处理方面SPCE061A更含有优势。基于SPCE061A设计了一个含有语音识别功效机器人。经过训练，训练人可使用多种命令让机器人完成很多有趣动作，使得人机交互更具智能化。

The Design of the Speech Recognition Robot
【Abstract】 The speech recognition is divided into two stages, namely, training and recognition. At the first stage, the speech recognition system learns about the human language and stores what it has learned in a speech database. Then at the next stage, the meaning of each inputted speech can immediately be found in the speech database. Sunplus 16-bit SPCE061ASCM is embedded with 32K word Flash and 2K word SRAM, with built-in 10-bit ADC and DAC as well as more than 14 interrupt sources. The core of its CPU is a 16-bit microprocessor chip which has the function of DSP. Besides, the CPU can work with a frequency up to 49 MHz, and process complex digital signals easily and quickly. Therefore, compared with other types of SCM, SPCE061A has more advantages in speech processing. Based on SPCE061A, a speech recognition robot has been designed. After training, the robot can complete many interesting actions according to the orders, which makes the human-computer interaction more intelligent.
