ros+科大迅飞语音包+图灵机器人（二）在ros上使用科大迅飞

• 在工作空间catkin_ws下创建一个包

• $ cd catkin_ws/src/

• $ catkin_create_pkg voice_system std_msgs rospy roscpp

• 把科大迅飞包里的代码复制到你创建的包里,并重命名为xf_tts.cpp

• $ cd SoftWare/samples/tts_sample/
• $ cp tts_sample.c ~/catkin_ws/src/voice_system/src/
• $ cd catkin_ws/src/voice_system/src/
• $ mv tts_sample.c xf_tts.cpp

• 到SoftWare/include目录下把include拷贝到voice_system包下

• $ cd SoftWare/include
• $ cp * ~/catkin_ws/src/voice_system/include

• 修改xf_tts.cpp文件（注意要把appid改为自己的appid,gtts.h等路径要改为自己该文件的路径）

• xf_tts.cpp的代码如下

• 1. /*

  2. * 语音合成（Text To Speech，TTS）技术能够自动将任意文字实时转换为连续的

  3. * 自然语音，是一种能够在任何时间、任何地点，向任何人提供语音信息服务的

  4. * 高效便捷手段，非常符合信息时代海量数据、动态更新和个性化查询的需求。

• 在CMakeList文件的“include_directories”后加入“include”，在文件末尾加入

• 1. add_executable(xf_tts_node src/xf_tts.cpp)

  2. target_link_libraries(xf_tts_node ${catkin_LIBRARIES} -lmsc -lrt -ldl -lpthread)

• CMakeList代码

• 在此时到catkin_ws下进行编译
• $ catkin_make
• 编译完后，roscore一下，重新打开窗口到catkin_ws下运行xf_tts_node节点
• $ cd catkin_ws
• $ rosrun voice_system xf_tts_node
• 此时，你能听到，“科大迅飞语音模块启动”的声音“

• 重新打开一个命令窗口，在catkin_ws下发布一个话题
• $ cd catkin_ws
• $ rostopic pub /voice/xf_tts_topic std_msgs/String 你好
• 此时，你会听到”你好的声音“

• 证明ros上运行科大迅飞语音模块成功
