It's called "skill-squatting" and computer security expert Robert Siciliano says your voice could trigger something bad.
"Unless you are very, very specific in your commands it is potentially possible you could get hacked."
Siciliano says it's similar to making a typo when entering the address in a web browser.
"This is not something high on my radar and as far as the worry factor, on a scale of one to ten, I'd say this is a 3 or a 4."
Siciliano says it's important you keep your Echo device and all computers up to date.
"Update your antivirus settings, make sure you have the latest version of your operating systems, download virtual private networks when you're on free Wi-Fi and keep the hardware and software on your Alexa device -- the firmware -- updated."
You may not even need to own an Echo device. As part of a deal with Marriott Hotels, Amazon is placing Echo devices in hotel rooms.
