步骤：

• 下载baidu_speech包

cd ~/catkin_ws/src
git clone https://github.com/DinnerHowe/baidu_speech.git

• 编译

cd ~/catkin_ws
catkin_make

• 安装requests模块

sudo pip install requests

• 安装两个Python库pyaudio和python-vlc

sudo apt-get install python-pip portaudio19-dev vlc libvlc-dev
sudo pip install pyaudio
sudo pip install python-vlc

• 测试百度语音包中，文本发音，向simple_speaker节点添加音频文件

roslaunch baidu_speech simple_speaker.launch
rostopic pub /speak_string std_msgs/String -- '你好，世界'

• 测试百度语音包中，语音识别

roslaunch baidu_speech simple_voice.launch

对着电脑说话，每次只识别一次，识别完成后需要按下Enter键才能继续识别
