Amazon Alexa's New 'Guard' Can Help Keep Your Home Safe While You're Away

Amazon Alexa can not only control your smart home, it can now protect it as well.

On Tuesday, Amazon introduced Alexa Guard, a feature that adds home security through any Alexa-enabled devices like the Echo smart speaker. Users can get automatic alerts when the device detects the sound of a smoke alarm, a carbon monoxide alarm, or glass breaking after you’ve told it that you’re out of town.

Alexa Guard will also let you know the kind of sound it thinks it has heard and send you an audio recording of that sound so you can confirm that, in fact, a burglar broke your window and not your 100-pound Labrador knocking over your glass planter again.

If you do find a sound alarming (pun intended), you can then use Alexa’s ‘Drop In’ feature to remotely check in on the situation and contact your home security, with a tap.

I can see potential for kids to use this to prank their neighbors.

You have any info on how to actually carry out a dolphin attack?

Researchers claim to have found a way to hijack the voice-controlled assistants, by using ultrasonic audio commands that dolphins can hear, but humans cannot. On most smartphones, the digital assistant is set up to listen for a “wake word”. For Google, the assistant takes orders once a person says, “OK Google”, while Apple’s assistant responds to “Hey Siri” and Amazon’s to “Alexa”.

Chinese researchers from Zhejiang University decided to create a program that could translate a standard human voice command and broadcast it in ultrasonic frequencies (over 20 kHz). These frequencies are too high for humans to hear, but they wanted to see if they were still audible to smartphones. To play these frequencies, the program needed very basic equipment, such as a smartphone, amplifier, ultrasonic transducer and battery, costing a mere $3 for the parts.

No but it seems straight forward.

Toasted Alexa

Seems as though the mic can pickup the high frequency sound and then business as usual.

Imagine if the brain worked this way.

It does, within the frequencies our ear can hear.

This tends to show that Alexa is not human.
