“Anyone who has used voice assistants knows that they accidentally wake up and record when the “wake word” isn’t spoken—for example, “Seriously” sounds like the wake word “Siri” and often causes Apple’s Siri-enabled devices to start listening….For the past six months, our team has been conducting research to go beyond anecdotes through the use of repeatable, controlled experiments that shed light on what causes voice assistants to mistakenly wake up and record. “

By having the speakers listen to 125 hours of shows on Netflix, including Gilmore Girls, The Office and The West Wing, the study measured how many times the speakers activated incorrectly. Conducted by scientists from Northeastern University and Imperial College London, the study  found that different shows had different rates of activation, ranging from 1.5 to 19 times per day. Microsoft and Apple’s speakers mistakenly activated the most frequently, followed by the Echo Dot 2nd generation, the Google Home Mini and the Echo Dot 3rd generation.

Gilmore Girls and The Office caused the most activations due to their large amount of dialogue, but all of the shows tested activated a smart speaker at least once. Activations ranged in length, with half of the Echo devices’ activations lasting six seconds or more all the way up to 43 seconds, the longest of any smart speaker. Words that contained the letter “x” typically triggered Alexa along with words contained the “k” or “g” sounds. Overall, just under 9%. of activations occurred consistently over 12 experiments, demonstrating a randomness to how smart speakers activate.

FAQs

Which smart speaker is the best?

The best smart speaker of 2020 is the Amazon Echo Plus. With its simple setup and full compatibility with other smart home products, this device continues to set the gold standard for smart speakers. We love the Dolby technology built into this speaker, ensuring a crisp and resonant output for music, Alexa communication, and just about any other sound you could imagine. Speaking of other sounds, the Echo Plus also features an intercom mode, allowing you to send messages throughout your home to other Alexa enabled devices. This device also features customizable security controls, allowing you to turn off the microphones for privacy.

What can smart speakers do?

If you think of your home as human body, then a smart speaker is akin to the central nervous system, essential for controlling the rest of the body (or in this case, the other connected devices in your home). Through Wi-Fi, smart speakers can hear your voice commands and perform an astounding array of functions, whether that’s playing a song, messaging a friend, or ordering paper towels from Amazon. All of the devices listed here are operated primarily through voice control, ensuring that whatever you need is but a few syllables away.

Are smart speakers always listening?

Smart speakers are always listening for their wake word. However, most of them only record after the user says the wake word.
