+LD3320语音识别模块和SYN6288语音交互模块可实现免录语音交互.两模块功能互补,即可识别语音,又可以进行语音合成，以及MP3播放，是开发新一代语音控制产品的理想方案.
5
+
6
+一．LD3320性能如下简介
7
+LD3320 芯片是一款“语音识别”专用芯片。该芯片集成了语音识别处理器和一些外部电路，包括 AD、DA 转换器、麦克风接口、声音输出接口等。本芯片在设计上注重节能与高效，不需要外接任何的辅助芯片如Flash、RAM 等，直接集成在现有的产品中即可以实现语音识别/声控/人机对话功能。并且，识别的关键词语列表是可以任意动态编辑的。
8
+二．功能介绍
9
+LD3320主要特征有：
10
+1、 通过快速而稳定的优化算法，完成非特定人语音识别。不需要用户事先训练和录音，理论识别准确率90%。
11
+2、不需要外接任何辅助的 Flash 芯片，RAM 芯片和 AD 芯片，就可以完成语音识别功能。真正提供了单芯片语音识别解决方案。
12
+3、每次识别最多可以设置50项候选识别句，每个识别句可以是单字，词组或短句，长度为不超10个汉字或者79个字节的拼音串。另一方面，识别句内容可以动态编辑修改，因此可由一个系统支持多种场景。
13
+4、芯片内部已经准备了 16 位 A/D 转换器、16 位 D/A 转换器和功放电路，麦克风、立体声耳机和单声道喇叭可以很方便地和芯片管脚连接。立体声耳机接口的输出功率为20mW，而喇叭接口的输出功率为550mW，能产生清晰响亮的声音。
14
+5、支持并行和串行接口，串行方式可以简化与其他模块的连接。
15
+6、可设置为休眠状态，而且可以方便地激活。
16
+7、支持 MP3 播放功能，无需外围辅助器件，主控 MCU 将 MP3 数据依次送入LD3320 芯片内部就可以从芯片的相应 PIN 输出声音。产品设计可以选择从立体声的耳机或者单声道喇叭来获得声音输出。支持MPEG1(ISO/IEC11172-3), MPEG2(ISO/IEC13818-3) 和 MPEG 2.5 layer 3 等格式。

In the context of the Robot Operating System (ROS), "Robot Control" usually refers to ros_control. This is a powerful software framework that acts as the "nervous system" of a robot, connecting the high-level brain (which plans movements) to the low-level muscles (the motors and actuators).
