And who never imagined conversing with someone who speaks another language, and understanding and being understood each in their own language, and if technology could do that even in a place full of people with a lot of noise, making you understand each word as if you had a simultaneous translator at your side.

That is exactly the proposal of TimeKettle's new W4 hearing aids that combine artificial intelligence and bone conduction technology to train clearer translation, even in chaotic environments such as airports and conference rooms. The big innovation is in how they pick up your voice, instead of just relying on the traditional microphone, they use the vibrations of the bones in your face to accurately recognize what you are saying, that eliminates virtually all background noise and allows the BBO OS software to do the magic.

Translate in real time in 42 languages ​​and 95 accents, with a delay of just 0.2 seconds. The company ensures that in addition to an accuracy of over 98%, the system understands the context of the phrases, even resolving confusion with similar words.

In practice you can use the headphones in two ways, in “one-to-one” mode, you hand a headset to the person you are talking to. Everyone chooses their language in the application and the translation happens simultaneously, almost like a normal conversation.

And in “listen and play” mode, both headphones stay with you. The app captures what others say, sends the translation directly to your ear and even plays out loud from your cell phone your response translated into their language, it's like having an invisible interpreter at the meeting table.

The package goes beyond real-time translation, the application saves conversation transcripts, generates automatic summaries and also allows you to download language packs for offline use without depending on the internet.

If you ever want to just listen to music or podcasts, the W4s also work as regular wireless headphones. The autonomy is 3 hours of translation with just one hour of charging and the compact case that weighs just over 116 g. Recharges hearing aids up to four times before needing a recharge and more TimeKettle already offers the W4 Pro, a more expensive version for $450 that allows for video translation and virtual meetings.

The idea is simple, to make international travel, business meetings or even casual conversations with people from different countries more natural and without the language barrier.
