In this video you will learn how to use the sound_play package for working with sound in ROS. You can use it for playing sounds from sound files or to make Text to Speech. Here you will also learn how to play sounds in a python notebook in ROS Development Studio. At the end you will learn how to apply all this to your Raspberry Pi.
