Alexa, Siri, Google Assistant – Your Smart Speakers, Your Privacy
Every year, people can expect something new: clothes, gadgets, or any items that someone may find useful.
Smart speakers are considered “in” nowadays, and it has a few models that people can choose from, allowing us to do a multitude of tasks from accessing wireless-enabled lights to placing an order for takeaways or products. It can even tell you the weather for the day, time, and date.
How Does A Smart Speaker Work?
What gets these smart speakers to work is voice recognition technology. As long as it recognizes someone’s voice, it would do what it is being asked to do.
There are a lot of voice recognition systems based on their manufacturers: Siri for Apple, Cortana for Microsoft, and Alexa for Amazon, to name a few.
Each smart speaker system may contrast with one another, but almost all have the same concept for them to work: making use of a wake word.
For example, Alexa is the voice recognition system for Amazon. When it hears the word Alexa, it turns itself on to receive commands from its owner. However, if the need arises, we can change the wake word.
Once the smart speakers hear the wake word, it turns on, records what we say, and sends it to the Amazon Alexa Voice Services (AVS) in the cloud. Once the speech is deciphered, it sends a response to the smart speaker.
As it uses many algorithms, it can “learn” the word choices that people usually use and their speech patterns.
Privacy and Data Security
Smart speakers don’t cost that much, and are very user-friendly. Although the thing that keeps them cost-friendly, the artificial intelligence (AI) processor of any vocal requests by the cloud servers that are manufacturer owned raises many privacy questions.
At Northeastern University in Boston, researchers show that sometimes smart speakers record by mistake when they did not “hear” the wake word correctly, but they almost stop within seconds once the mistake is realized.
That may seem alright to people, but some manufacturers allow their employees or third-party contractors to listen to recordings to improve the smart speaker’s voice-recognition programs.
There are claims that if people knew, they would’ve used smart speakers differently. But fret not; here are a few settings that can help things stay private with the smart speaker.
Top Voice Recognition Systems and Their Privacy Settings
Alexa Voice Recognition System

Go to Settings, then select Alexa Privacy, then go to Manage How your Data Improves Alexa. Toggle off the following:

If you see the warning message that says voice recognition and additional features might not work if you turn the setting off, you can ignore that.
- Press the microphone On/Off button at the top of the smart speaker.
- Just press the button again if you need to use it.
- If you have a different smart speaker that uses Alexa, check the manufacturer’s instruction pamphlet to mute your device.
To review/delete recordings: Go to Settings on the app, then select Alexa Privacy, then finally choose Review Voice History.
If you delete all the recordings, it might hinder the voice recognition’s ability to know your voice, and it will only affect the recordings you’re done with.
