On a quiet evening, the telly goes dark but the room doesn’t quite feel “off”. The little standby light glows, your phone pings in the kitchen, and something in the back of your mind wonders how many gadgets are still paying attention. You mute the adverts, not the living room.
For one reader it started with a throwaway line in a news piece: “Smart TVs with always‑listening microphones can capture audio even in standby.” They went into the settings “just to check”, expecting to find nothing. Buried three menus deep sat a switch called Voice recognition set firmly to On, with a note about sending recordings to “improve services”.
That’s the setting privacy campaigners keep pointing to. Not the brightness or the sleep timer, but the microphone mode that allows your TV to sit, quietly, listening for a wake word while you assume it’s resting. The fix is not dramatic. You change one option… and the room actually goes still.
The quiet microphone in the corner of the room
Most modern smart TVs, soundbars and streaming boxes ship with far‑field microphones. They’re the reason you can say “Hey Google”, “Alexa” or “Hi TV” from the sofa without touching the remote. To do that, the device has to listen all the time, including when the screen is off and the set looks asleep.
Manufacturers will tell you that the clever bit happens after you say the wake phrase. Short snippets of speech are packaged up and sent to cloud servers, where they’re turned into text and matched to commands. Those snippets may be stored to “improve recognition” or train algorithms, often tied to your device or account.
Privacy advocates focus on the bit before that wake word. An always‑on microphone is still present in the room, technically able to pick up whatever happens in front of it. Even if companies promise not to keep what they hear, the risk surface changes: a bug, a misheard command, a poorly secured account, and your living‑room chatter stops being purely yours.
The one setting that makes the biggest difference
In most menus it hides under a bland label: Voice recognition, Voice assistant, Hands‑free voice, or simply Microphone. This is the switch that turns always‑listening on or off. Privacy groups consistently recommend disabling this mode on TVs and companion boxes, then using push‑to‑talk buttons if you still want occasional voice control.
Turning off hands‑free listening does two things. First, the TV stops monitoring the room for a wake word when it’s in standby or showing a programme. Second, in many cases it limits when audio can be sent to the cloud at all, because you have to hold a button on the remote to start a short, deliberate voice session. You move from “ambient listening” to “only when I say so and press something”.
Some sets go further and have a physical mic switch or slider on the frame or remote. That’s the gold standard: when the hardware line to the microphone is cut, no software update or obscure setting can silently re‑enable it. If your TV has that little switch with a mic icon, privacy advocates would like you to flip it down and leave it there.
Exactly how to switch it off on popular TVs
Every brand buries the toggle in its own way, but the pattern repeats: Settings → Privacy or General → Voice / Microphone.
Samsung Smart TV
Go to Settings → General & Privacy → Voice or Voice Recognition. Turn Voice Recognition off. On some models there’s a separate Listening to voice commands option you can disable. If your remote has a mic button, you can still press and hold it to issue a command without hands‑free listening.LG webOS TV
Open Settings → All Settings → General → AI Service or Voice. Turn off AI Voice, Voice Recognition and any “Hi, LG” or wake‑word options. Check User Agreements and decline optional “voice data” collection if the menu allows it.Sony / Google TV / Android TV
Press Settings → Privacy → Google Assistant or Search. Turn off Hey Google / OK Google detection on the TV. You can also go into Apps → See all apps → Google → Permissions and revoke Microphone access if you never want the assistant to listen.Amazon Fire TV (stick or built‑in)
On a Fire TV Edition set, open Settings → Preferences → Privacy Settings. Turn off options mentioning microphone data or voice recordings, and disable Alexa Hands‑Free if you see it. Use the remote’s Alexa button only when you actually want to speak.Other brands (Hisense, TCL, Panasonic, etc.)
Look under Settings → System or Privacy → Microphone, Voice or AI. If the TV uses Google TV or Roku, follow their assistant or privacy menus and turn off wake‑word detection and voice data collection.
On any set with a physical mic toggle, use it. The small LED next to the logo or camera is a clue too: if the TV claims to be muted but the “listening” light is still on, dig deeper into the menus until both agree.
What actually changes when you turn voice listening off
You lose the party trick of calling across the room for the volume to drop. You’ll scroll through apps with arrow keys instead of asking for “BBC iPlayer”, and you may have to type search terms rather than dictating them. For some people that’s genuinely useful, especially for accessibility.
What you gain is a tighter boundary between your private life and a company’s servers. Fewer accidental activations, fewer snippets of background conversation stored and analysed, less behavioural data to feed into advert profiles. The TV becomes more like an old‑fashioned screen again: it shows you things, rather than listening back.
One thing doesn’t change automatically: tracking of what you watch. Many smart TVs have a separate feature-often called Viewing Information Services, ACR (automatic content recognition), or Personalised ads-that logs your viewing to build advert profiles. If you care about privacy, the mic switch is step one, not the whole job.
Other privacy switches worth checking
Once you’re in the menus, it’s worth spending five extra minutes on the rest. Think of it as a quick MOT for the digital bits of your telly.
Turn off viewing data collection
Look for Viewing Information, ACR, Smart Interactivity or similar and set it to Off. This stops the TV scanning what’s on screen to report back for advert targeting.Limit personalised advertising
Under Privacy or About, you may see Interest‑based ads or Personalised adverts. Turn these off where possible, and reset any advertising ID the TV offers.Review app permissions
Open the apps list and check permissions for big services or the built‑in assistant. Remove microphone or camera access from anything that doesn’t need it to function.Fence your TV on the network
If your router allows it, put smart TVs and gadgets on a separate “guest” Wi‑Fi or IoT network. That way, if one device is compromised, it has fewer paths into laptops and phones.Cover cameras when not in use
Some sets have pop‑up cameras for video calls or gesture control. Retract them or cover them with a simple slider or sticker when you’re not actively using them.
Here’s a quick snapshot of the main switches to hunt down:
| Setting | Typical menu path | Why it matters |
|---|---|---|
| Voice / mic / wake word | Settings → Privacy / General → Voice / Mic | Stops always‑listening in your lounge |
| Viewing info / ACR | Settings → Privacy / Terms / Viewing Data | Reduces tracking of what you watch |
| Personalised advertising | Settings → Privacy → Advertising / About | Cuts down profiling for targeted ads |
Once you’ve done this on one TV, the pattern clicks. You stop scrolling past “Privacy” as if it’s just legal small print, and start treating it as part of the basic set‑up, alongside connecting to Wi‑Fi and tuning channels.
Why campaigners keep coming back to the mic
From a regulator’s point of view, microphones are different from simple viewing stats. They can pick up arguments, children’s voices, health chats on speakerphone, even work calls taken on the sofa. That’s not data most people expect to share with a television maker or advert broker.
Campaigners argue that default‑on listening flips the usual bargain: you have to find and disable something you never knowingly enabled. They’d like to see hands‑free mics set to off by default, explicit prompts before any audio is stored, and simple hardware switches on every device that can hear you. Until that becomes normal, they keep giving the same advice: check the mic setting today, not “when you get round to it”.
FAQ:
- Is my TV definitely recording me if the microphone is on?
Not necessarily. Most manufacturers say they only store short audio clips after a wake word or when you press a voice button. The concern is less about what they promise and more about what’s technically possible if something goes wrong.- If I mute the TV or lower the volume, does that stop it listening?
No. Muting only affects what you hear. The microphone and speakers are separate parts. You need to use the mic/voice settings or a physical mute switch to stop listening.- How can I tell if my TV has a microphone at all?
Look for a mic icon on the remote, small pinholes labelled “mic” on the frame, or references to “voice assistant/voice search” in the manual. If the spec sheet boasts hands‑free voice control, there is a microphone somewhere.- Is unplugging the TV the only truly safe option?
Physically disconnecting power is the most cautious approach, but for most households disabling hands‑free voice and using any hardware mic switch is a strong, practical compromise.- Does this advice apply to smart speakers and soundbars too?
Yes. Any always‑listening device in the home raises similar questions. Smart speakers and voice‑enabled soundbars usually have a dedicated mic‑mute button; turning it on when you’re not actively using voice commands is a solid habit.
