Startup's New Device Aims to Jam AI Wearables, Faces Skepticism

A new startup named Deveillance has introduced its first product, the Spectre I, a portable tabletop device designed to prevent nearby gadgets from recording voices. The Spectre I combines ultrasonic frequency emitters with artificial intelligence to block devices from capturing speech and to detect nearby microphones. The device is still in development, with an expected release in the second half of 2026 at a price of $1,199.

The announcement of the Spectre I generated significant attention on social media, with some praising it as a form of resistance against the proliferation of always-listening AI wearables, while others expressed skepticism about its effectiveness. Aida Baradari, the founder of Deveillance and a recent Harvard graduate, was inspired to create the device as a response to the increasing presence of AI devices that constantly listen, such as Amazon-owned Bee AI's bracelet and the Friend pendant. Baradari emphasizes the importance of privacy in conversations and the need for individuals to control what they share.

Concerns about privacy have been growing, particularly with the expansion of government surveillance and the private sector's involvement in data collection. For instance, the home security company Ring faced backlash after a Super Bowl commercial highlighted privacy issues, leading them to cancel a partnership with another controversial security firm, Flock Safety. Benn Jordan, a musician and YouTuber, notes that people are becoming more aware of the lack of privacy in their daily lives.

Despite the intentions behind the Spectre I, there are doubts about its feasibility. Ultrasonic microphone jammers have existed since before the Cold War, but they are typically bulky due to the space needed for frequency emitters and power sources. Baradari acknowledges the challenge of creating a compact yet effective device, noting that the current version of the Spectre I emits an audible hum.

The Spectre I aims to use AI to generate cancellation signals that confuse automatic speech recognition technology, but experts like linguistics professor Melissa Baese-Berk point out the variability in human voices, which complicates the task. Additionally, Deveillance claims the device can detect nearby microphones using radio frequencies, though critics argue this method is ineffective unless the sensor is very close to the microphone.

Deveillance is exploring the integration of nonlinear junction detection (NLJD), a technology used by security professionals to locate hidden microphones. However, NLJD detectors are typically expensive and used in specialized contexts. There are also concerns about the potential effects of ultrasonic frequencies on humans and animals, with Baradari acknowledging the need for further testing.

Critics like engineer and YouTuber Dave Jones have expressed skepticism about the Spectre I's capabilities, suggesting that the device may only be able to detect Bluetooth audio devices rather than all types of microphones. Baradari has responded to critiques by stating that the technology is still being developed and that feedback is helping to refine the product.

Despite the skepticism, Baradari remains optimistic about the Spectre I, aiming to address the concerns raised and make the "cone of silence" a reality. The Deveillance website reflects this goal, and the company continues to work on improving the device's functionality.
