Listening to your tunes, but your neighbor is feeling chatty? Ordering a latte but your hands are full so you can’t pause your podcast? Conversation detection, a feature on some headphones and earphones, can be a game-changer. Instead of removing your active noise-canceling earbuds or using your hands to pause the audio, this handy feature detects voices, pauses the audio and turns off the noise canceling.
That seamlessness between the cozy comfort of noise cancellation and the bustling real world is extremely helpful and easy to set up. There are, however, a few important things to note for the best experience with automatic conversation detection.
Most noise-canceling earbuds, including those from Bose and many other manufacturers, have a mode called Aware, Awareness or Transparency. This boosts ambient sound, often in the vocal frequency ranges. What I’m talking about here is a detection feature that makes switching to this mode automatic instead of having to manually select it.
You’ll generally see this feature on flagship headphones from Apple, Sony, Google and Samsung. Each one calls it something slightly different: Apple has Conversation Awareness, Samsung has Voice Detect, Google has Conversation Detection and Sony’s got Speak-to-Chat.
How it works
Enable
Conversation modes are generally accessible in the settings for your headphone’s companion app. If your phone and headphones are both Apple or both Google, go into the phone’s settings and access this feature by tapping on your headphones. Always be sure to update all of your devices’ firmware. Apple iOS also provides access to Conversation Awareness via the Control Center that appears when you swipe down from the top of the screen.
Detect
The array of tiny microphones built into your earbuds/headphones for calls and noise canceling will detect your voice for a Conversation Awareness mode. Many headphones have built-in accelerometers for features like head tracking and on-ear/head detection; these might also be used to pick up jaw movement to verify that it’s you speaking and not someone nearby.
Samsung has a separate but related Siren Detect feature that automatically turns on transparency mode when a siren is detected, so you can hear what’s going on in an emergency. (Some brands do the opposite and crank up the ANC when a loud sound is detected.)
Auto-adjust audio
Once activated, Conversation Awareness modes also either pause or lower the volume of whatever audio is currently playing. This behavior differs by brand. For example, Apple devices lower music audio but pause podcasts. Samsung, instead, lowers all audio, while Sony and Google devices both pause all audio. Ideally, you’d be able to choose the behavior, but currently that’s still rare. Apple adds Conversation Boost, which uses the mics and accelerometers to amplify the voice of the person you’re talking to via head tracking.
End chat and resume
Then, either through some technological wizardry or simply by sensing when you stop talking (adjustable on some brands, including Sony), the headphones detect that the conversation has ended and revert to the previous audio, at the same volume and in the same noise-cancellation mode. Many models are better than people at detecting the end of a conversation.
Any model with this feature will also let you toggle the conversation mode on/off manually with a long button press or similar action.
The fine print
Conversation detection is triggered by your voice, not someone else’s, so you may wind up asking people to repeat themselves when you notice they’re talking to you. This asking will trigger conversation mode. Depending on how a specific model’s detection works, it might require both earbuds to be in your ears for it to work.
Sometimes, conversation detection can be triggered inadvertently by coughing, singing along to music, or other random ambient sounds. It may also not work well in extremely noisy environments, such as construction sites and airplanes. Some models do let you adjust the sensitivity, which is something we’d like to see more of in firmware updates and future releases.
Frequent podcast or audiobook listeners should choose headphones that pause all audio for conversations, or at least handle it intelligently by distinguishing between audio types and pausing podcasts/audiobooks so you don’t miss anything. Unfortunately, Apple and Samsung won’t pause videos from services like Netflix or YouTube; they just lower the audio.
As with all features that use sensors and mics, conversation detection will affect battery life to some degree, though it’s not a major drain.
The final verdict
Conversation detection modes aren’t for everyone, especially exuberant souls who talk to themselves at full volume, yell at the news or sing along with their tunes. If you reflexively take your earbuds out to talk to others, you also don’t need this feature (unless you want to change that habit). In the future, I’d like to see more adjustability, but even how this feature is implemented in the current crop of headphones and earbuds, it’s an excellent upgrade to the seamlessness of digital life.
