LG disputes claims of passive audio surveillance in smart TVs

LG Electronics has strongly denied recent reports that its smart TVs function as passive surveillance devices. In a statement provided to Al Jazeera, the company clarified that its televisions do not record background noise or ambient conversations. According to LG, audio data is only processed when a user actively presses the voice button on the remote or speaks the specific wake word, and only after they have enabled the Far-Field voice recognition feature.

The dispute follows a detailed investigation by tech outlet Gamers Nexus, which worked with independent security researchers. They reported that LG TVs may continue to process audio even when the main microphone switch is off, potentially capturing conversations from up to 12 meters away. The researchers suggested that this behavior affects a significant portion of LG’s global smart TV base, raising serious concerns about privacy in the home.

Researchers identify persistent data storage

The core of the controversy lies in how long audio data remains on the device. Researchers claim that if a wake word is not clearly recognized, or if there is silence after a command, the audio may be stored locally as plain text. This data can remain in temporary buffers even if the TV is disconnected from the internet, waiting to be uploaded to LG servers later. Such persistence contradicts the idea that voice data is processed and discarded in real-time.

Security experts argue that this design creates a significant risk. Because smart TVs often remain in homes for years, sometimes beyond their official support period, any vulnerability in how they handle data becomes a long-term threat. A compromised device could potentially be exploited to capture sensitive conversations, placing private discussions at risk if the hardware is not properly secured or patched.

LG asserts explicit user control

LG maintains that its systems are designed with user consent at the forefront. The company states that audio is immediately deleted if the wake word is not correctly identified. It emphasizes that no ambient sound is collected unless the user explicitly initiates a voice command. This stance suggests that any recording observed by researchers is a result of specific user interactions rather than a default passive listening mode.

However, privacy advocates question the necessity of retaining data after a command is issued. They argue that if voice recognition is the primary goal, the audio should not need to be stored for later analysis or logging. The lack of clear explanation from LG regarding the purpose of retained data leaves a gap in public trust, especially given the company's broader use of household data for its advertising business.

Unverified claims and consumer caution

It is important to note that the specific technical claims made by the researchers have not been independently verified by news organizations. While LG’s denial is official, the detailed methodology presented by the investigative team raises valid questions about the transparency of smart home devices. Consumers are advised to review their privacy settings carefully and consider disabling voice features if they are not actively used.

As the debate continues, the focus remains on the trade-off between convenience and privacy. Smart TVs offer seamless voice control, but the underlying mechanisms for data handling must be transparent. Until LG provides a clearer technical explanation for any retained audio data, users should remain cautious about what their devices might be recording in the background.
