I've been getting acquainted with the NAO robot through Choregraphe, and I just switched over to using ROS. I've gotten the naobringup to launch and I can access camera feeds and everything, but when I try to publish to /speech the robot doesn't say anything. This is what I tried: `rostopic pub /speech stdmsgs/String "data: 'Hello'" If Irostopic echo /speech`, my message appears, but the NAO isn't saying anything.

Any ideas?
