Summary
- Most smart speakers send data to the cloud for processing, which raising legitimate privacy concerns about what happens to your data.
- Privacy-focused smart speakers like Apple’s HomePod and Home Assistant’s voice assistant provide alternatives.
- Balancing convenience and privacy with smart speakers is crucial, but right now there aren’t a lot of options to choose from.
Your smart speaker might be your favorite online companion, but is it also eavesdropping on your private conversations and sending them to the cloud?
Most Smart Speakers Send Data to the Cloud
Smart home gadgets have become deeply integrated into your daily routines and offer convenience and efficiency, including hands-free assistance for tasks like controlling home devices, setting reminders, and playing music. This includes voice-activated virtual assistants, such as Amazon Echo and Google smart speakers.
These devices are designed to listen for specific wake words that activate the smart device, transmitting your data to cloud servers for processing. That’s not entirely the case, though.
Some manufacturers claim that recordings only happen when the wake word is detected. However, a study showed that there were instances where mis-activations occurred, leading to unintended recordings. This raised some privacy concerns over the extent of data being collected and its potential misuse.
In simple terms, smart home devices tend to “monitor” everything but send nothing to a cloud server until the wake word is detected (of course, we know this isn’t always true). But even if it was, isn’t this still a significant invasion of privacy just to turn some lights on? Cloud storage and its security are also a factor. Where your data is being stored, for how long, and how secure it is from data breaches are all valid questions.
Human reviewers also listen to recordings for AI training, which raises some privacy concerns, especially if you aren’t able to opt out.
Why Smart Speakers Need to Use the Cloud
Smart devices by nature need to connect to the cloud, especially for advanced queries such as searching the internet. Using voice commands with a smart assistant such as Google Assistant is a simple task. Just utter a few words, and it will do what you ask it to do, whether that’s to play some holiday music or set a reminder to call your mom.
But it’s not as easy as it looks. A device that’s able to recognize words and interpret human speech is a complex process, and there’s a ton of work that goes into the backend. Voice recognition technology continues to improve with AI, and someday an AI may be taking your order at your local fast food joint.
Since this technology is quite resource-intensive, it means that it requires substantial computational resources locally, including hardware with significant processing power. These aren’t all feasible for consumer-type devices. So, by using cloud servers, smart speakers are able to handle complex voice recognition processes more efficiently.
However, the reason isn’t purely technical. Companies also benefit from data collection for analytics to improve their services, or sell the data to third parties (depending on their privacy policy).
Privacy-Focused Smart Speakers Already Exist
Privacy and security are equally important, especially as you become more concerned about data breaches that are happening on an unprecedented scale, you may want to consider a privacy-focused smart speaker.
Although not entirely off-server, the HomePod from Apple promises local processing by handling commands on-device to strengthen your privacy protection. Yes, some commands still need to connect to Apple’s cloud servers, just like Google and Amazon’s smart speakers. It’s not fully offline, but it’s a start.

Apple HomePod Mini
The Apple HomePod Mini is a Siri-enabled smart speaker for those invested in the HomeKit ecosystem. Compact and discreet, the HomePod Mini is available in five different colors, too.
On the other hand, brands like The Home Assistant voice assistant are entirely local and claim that no information is sent to the cloud to ensure user privacy. Launched in 2023, this device supports over 50 languages, operating without the reliance on cloud services that other smart speakers rely on. It’s designed for home automation and privacy-focused smart home management, and integrates seamlessly with the Home Assistant ecosystem, performing tasks that include operating smart TVs and smart light control.
So, what’s the catch? You’ll need to leave behind the more advanced functionalities that require a cloud server connection. It’s still pretty basic compared to the mainstream speakers on the market today.
There’s another trade-off too. The initial setup may require more technical knowledge compared to a standard smart home device, but that shouldn’t put you off. The open-source company offers extensive documentation, a community forum, and a Discord chat server that can help if you get stuck on anything.
Alternative Options to Choose From
Since achieving optimal functionality while not sending data to cloud servers isn’t yet possible right now, you still have a few options to think about when it comes to choosing a smart device while protecting your personal data.
One alternative is to use offline voice assistants, which similarly offer similar functionalities but without the data being sent to remote cloud servers. Offline assistants may not have the same level of functionality as Alexa, Siri, or Google Assistant, but how do you know it’s not enough for your needs? Especially with AI integration with home devices becoming a thing, it may just impress you.
Aside from Home Assistant, there are products including the community-driven platform OpenVoiceOS, an open-source voice assistant software platform that uses AI to power their voice assistant functionalities, and only sends minimal data to cloud servers.
As a user, you can set up your account to be fully offline for wake word detection, voice recording storage, and text-to-speech to prevent any of your data from being sent to the cloud. It shares similar trade-offs to Home Assistant in that you need technical knowledge to set up and maintain OpenVoiceOS and some features may require internet access. It’s also still in development, so it’s not going to be as stable or complete compared to your standard smart home devices.
To increase the security of your smart home devices, you can generally turn off voice history, auto-delete stored recordings, and mute microphones when not in use. You can also disable third-party integrations that may collect more data than necessary, by reviewing and revoking permissions in your smart assistant app.
The final option is to wait for AI integration with voice assistants to get better, which may eventually fulfill the need to go offline completely with smart speakers, but with all the advanced functionalities present.
It’s All About Balance and Choice
You may still be concerned about smart speakers unintentionally recording things they shouldn’t. Fortunately, there are a lot of privacy settings you can play around with on your smart home app to make things a little more privacy-conscious. If you’re using Alexa, you can even download your entire voice history and data that Amazon stores on you.

Amazon collects way more data than you think.
Ultimately, it’s about striking the right balance between convenience and privacy when it comes to using smart speakers and, while some brands may collect minimal data, there’s no perfect device on the market right now. These tools continue to improve your productivity and can be helpful companions in your day-to-day life.
However, their reliance on cloud server processing brings justifiable and real concerns regarding data privacy and security, and many already believe that a real smart home should work offline.
The convenience of smart home assistants is becoming irreplaceable in home automation, entertainment, and using technology to make life a little easier. Who doesn’t enjoy how efficient Alexa or Siri are when answering calls, reminding you of your appointments, or knowing what your favorite playlists are? Isn’t this useful enough to overlook the potential risks?
Yes, the risks are very real, and we should do as much as we can to protect our privacy, but the benefits are here to stay as well, so it’s up to you to make the right choice for you.
