If you connect a plug to the audio jack, sure, the laptop probably defaults to using that jack for input and output. But you can still choose to use the built-in mic, right? So it's not physically disconnecting anything, just triggering a software disconnect.

AFAIK you're correct. Though it's possible most spying software just uses the default mic and doesn't have the capabilities to switch the input device?

Not a Mac user, and the last time I played with sound stuff in nix was almost 15 years ago...

But I feel like switching input (or even collecting multiple sound inputs) on a nix OS is not much more convoluted than dealing with the sound stack in general. But that's probably also related to how the driver itself interfaces with the audio device...

Supposedly your smart phone and smart TV are not passively listening to your offline conversations. That's only done on a targeted basis to people who are being monitored. Your location history however is being passively tracked. Not defending it, but your smart phone is not quite as bad as Alexa. At least for the moment.

> That's only done on a targeted basis to people who are being monitored. Your location history however is being passively tracked. Except Amazon was caught with their hands in the cookie jar listening on 'regular' people's private conversations on more than one occasion.

Can you share more details?

> My laptop has a microphone and video. Surely Microsoft could just start recording with the with right windows update? It's a commonly mentioned issue, and a somewhat regular occurrence with various malware or "security solutions". That's why a number of laptops have either visual indicators or shutters (though mostly for the cameras, sadly hot mics are rarely a consideration), and a rare few have physical disconnec…

Macbooks since 2018 physically disable microphones and webcams when the lid is closed: https://www.businessinsider.com/apple-macbook-air-and-2018-m...

But the lid is open for several hours a day while I'm working!

You'll note that "OK, Google" works when your phone is on flight mode. Google aren't constantly sending your microphone data to their servers, the recognition of that phrase happens on your device.

Yes, they can't constantly send microphone data even if they wanted due to power constraints. They use a dedicated DSP chip with the sole purpose of detecting the hot word.

then stabb the mic afew dozen times, and feed the hotword to the DSP with a button, or better yet use another DSP to bridge your own custom interface to the "hotword sniffer"

typing to an alexa device should be an option, just like having an AI chat.

6 years ago I used to work for a translation agency.We used to get some very confidential (and very interesting) texts from banks. We were not allowed to put a single word into google translate from client files and this stuff is 10 times worse. Having a permanent mic from large corps in your home is never a good idea...

> You're trusting that the microphone is not listening The point of the original comment is mostly that devices like echos are expected to always be listening, and this has legal implication.

Can the police right now go to Amazon and demand to listen to anyone's Alexa in real-time? Can the NSA go to any landline provider, and demand a secret list of a person's entire call history(or they may already have this already)? The biggest profile case where Alexa audio recordings got turned over was during a murder trial after a judge's orders. I am not entirely clear that the ramifications of Kyllo v. United Sta…

Police- maybe some court decision is required. NSA- I very much doubt so.

Even if it's illegal, it would be better if it was simply not possible in the first place.

you have to give explicit permissions for those things. google assistant doesn't work on my phone because i never gave it permission to enable that feature.

me neither but i have no way of verifying if this is the truth or not without installing a vpn with a firewall and analysing the logs

It doesn't even matter how sincere they are. False negatives hurt the perception of the product, because then people need to repeat the key word. False positives do not hurt the perception of the product, because the recording occurs silently. Their incentives are aligned against privacy, and so privacy will suffer.

False positives does hurt the perception, because the device will usually do something or utter a response unless it fails to detect something intelligible or writes the request off as not intended for it (having two devices at opposite ends of a large open space living area can sometimes get frustrating, but looking at the history, you see how often they correctly determine which device should respond) An occasional…

That's not true. Amazon can have a significantly more accurate classifier running on their backend that processes the transmitted audio. And this classifier can be more accurate due to both more computation and it would have access to the entire data stream, not just the initialization words. You would never know that your data was sent to Amazon and then ignored.

The recorded conversations are accessible via Amazon. You can go and listen to them yourself, and delete them.

Only after the wake word has triggered the "start interpreting audio" code. These things are NOT constantly streaming everything they hear to the cloud (and this can be easily confirmed by monitoring traffic from the device's IP address on your network). That is a big distinction.

I'm willing to believe that it's only after it's been triggered by the wake word processing. The problem is a lot of things I say that aren't the wake word still triggers a wake up. If you've got one of these, turn on the accessibility options to make noises when it wakes up... I'm not a heavy user, so more than half of the wakeups aren't intentional.
