2. Voice control of car movement

Take our company's product Rosmaster-X3 as an example to explain how to call the Speech_Lib library in the program for voice recognition and then control the movement of the car/robot. This course needs to be combined with the Rosmaster-X3 car hardware, and only code analysis is done here. First, let's look at the built-in voice commands,

1. Start the program

Terminal input,

xxxxxxxxxx
roslaunch yahboomcar_voice_ctrl voice_ctrl_yahboomcar.launch

2. Core code

Code path: ~/driver_ws/src/yahboomcar_voice_ctrl/scripts/voice_Ctrl_Mcnamu_driver.py

xxxxxxxxxx
#导入语音识别的库 Import the speech recognition library
from Speech_Lib import Speech
from Rosmaster_Lib import Rosmaster
#创建语音识别的对象和驱动控制对象 Create speech recognition objects and driver control objects
spe = Speech()
car = Rosmaster（）
#读取语音识别到的内容 Read the content of speech recognition
speech_r = spe.speech_read()
#发送语音播报内容 Send the speech broadcast content
spe.void_write(speech_r)
