AI Thread Summary
Automatic speech recognition systems pose risks for eavesdropping, prompting the development of a method to camouflage voices in real-time without disrupting conversations. Traditional adversarial attacks are ineffective in streaming scenarios due to signal changes, leading to the introduction of predictive attacks. This innovative approach forecasts the most effective future attack, significantly enhancing performance against systems like DeepSpeech, achieving a 3.9 times reduction in word error rate and 6.6 times in character error rate compared to baseline methods. The technique has been validated in realistic environments and over physical distances, showcasing its practical effectiveness. Audio samples and further resources are available online.

An interesting approach to those eavesdropping devices in your life.

ABSTRACT
Automatic speech recognition systems have created exciting possibilities for
applications, however they also enable opportunities for systematic eavesdropping.
We propose a method to camouflage a person’s voice over-the-air from these
systems without inconveniencing the conversation between people in the room.
standard adversarial attacks are not effective in real-time streaming situations because
the characteristics of the signal will have changed by the time the attack is
executed. We introduce predictive attacks, which achieve real-time performance by
forecasting the attack that will be the most effective in the future. Under real-time
constraints, our method jams the established speech recognition system Deep-
Speech 3.9x more than baselines as measured through word error rate, and 6.6x
more as measured through character error rate. We furthermore demonstrate our
approach is practically effective in realistic environments over physical distances.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'
Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
