A new device aims to give people control over who can hear them in a world full of devices that are constantly listening and recording your conversations. A startup called Deveillance has introduced Specter I, a wearable device designed to prevent microphones in nearby devices from recording your voice.
Today we introduce Specter I, the first smart device that stops unwanted audio recordings.
We live in a world of always-on listening devices.
Smart devices and AI dominate our world in business and personal conversations.

The company says the device can make conversations unintelligible to phones, smart speakers, laptops and other devices that constantly listen to audio. The idea addresses the growing concern about always-on devices.
According to the company, around 14.4 billion devices worldwide continuously listen for voice input. These records often become valuable data sources used for data mining, training artificial intelligence systems, and influencing our purchasing behavior or our deepest opinions.
Even a short speech sample can reveal sensitive personal details. About 30 seconds of voice data can help determine characteristics such as age, weight, income level and even health information.
A device that creates a privacy bubble around your voice

Specter I works by creating a two-meter protective zone around the user. When activated, it scans for nearby microphones and emits signals that humans cannot hear but microphones can detect.
These signals overlay your speech, causing recording devices to receive distorted audio signals that cannot be understood.
Unlike traditional signal jammers that rely on strong radio interference, the device uses artificial intelligence, signal processing and physics research to directly attack microphones.
The system works locally on the device and does not send any data to the cloud. Specter I’s portable design makes it easy to carry anywhere.

According to Deveillance, this makes it useful in business meetings, personal conversations, or in situations where the discussion needs to remain private.
The company has opened pre-orders for Specter I with a refundable deposit of $1,199. The device is currently in development, with first deliveries expected in the second half of 2026.
Privacy groups like the Electronic Frontier Foundation have long warned about the risks of constant surveillance. Deveillance says Specter I is just the beginning of its efforts to give users more control over how their data is collected and shared.
