@Guilherme-Aquino, what if instead of using the routine, you say, "Alexa, ask TRIGGER C M D to run script" to your Echo device? Does it say the result of the script?
Also, you wrote, 'when i run the routine and choose "echo" instead "my smartphone device"'. Did you mean you switched the FROM field in the routine from "This mobile device" to name name of our echo device, and that's all you changed?
I'm not sure yet because your echo device should be able to say the result just as well as your smart phone's Alexa app. I just tried it and it worked for me. It should only beep if you're using the TRIGGERcmd Smart Home Alexa skill.
