Yes that is the technical conclusion. But maybe the most important thing is that we have to do an actual teardown of the product in order to have some confidence that Amazon is not lying on it's Echo capabilities.

To be clear, I am not saying we should trust Amazon & Co, I'm saying that if that's the level of trust we have with home assistance devices, why even bother with the stuff ?

The stakes are so high for Amazon to tell the truth here. If they were lying then there would be outrage among users, media, competition, etc.

I’ve dealt with many people from Amazon in my professional life and based on their handling of customer data I believe Amazon take seriously the trust customers place with them. Amazon believe the Alexa and Echo platform will grow their retail and service relationships with customers.

I don’t think they would throw that away to fool us all into believing a fake mute button - for what?

Re:Amazon Echo Flex: Microphone mute button appears to be re... by everdrive on Tuesday January 12, 2021 @08:05AM (#25746258)
I think both you, and the parent you're responding to are correct. Amazon is not evil, they're merely self-interested. This can lead them to do some evil things, but they are not a cartoon villain, twisting their mustache in shadows.

On the other hand, it's important to verify claims, and Amazon should be very happy about this verification. It proves that their claim could be trusted. Some other conclusion could have just as easily been true.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by verbify on Tuesday January 12, 2021 @09:17AM (#25747164)
Couldn't they have implemented mute in software? There would be little outrage if they had (users don't care about the difference) but spy agencies (e.g. NSO Group) would have a backdoor.

The fact that they used a hardware switch means they did it the right way.

By contrast my Logitech camera has a light to show when the camera is running - but the light can be disabled via their software which makes me uncomfortable with fully trusting the light.

When we discussed this - at long length - during the original Echo development program, we consistently came to the conclusion that it should be hardware, not software, to maintain customer trust.

Are you still involved? If so, is there some way I can request a feature to turn off all of the "by the way" and other follow-ups? I find them incredibly annoying. I usually answer "no and don't ask again" but it doesn't seem to understand.

My question for you is why not advertise this loudly? Or, maybe you did and no one cared? Because presumably it's a bit more costly per unit to do it this way, and very few people are ever going to understand and care.

Not that I think you made the wrong choice, I think it's a good one, but I'm just curious how many consumers you thought would actually understand it, or how that information would be distributed

Re:Amazon Echo Flex: Microphone mute button appears to be re... by sib on Tuesday January 12, 2021 @04:14PM (#25753779)
It's a balancing act. We built it, to build trust. But talking about it too much would - we thought - highlight concerns and increase worries that we hoped (most) users wouldn't have.

As an example, we were very clear and upfront in the original product detail page that users' voices went to the cloud, as we were not trying to hide that. Even so, some people tried to play a bit of "gotcha" and fear-mongering about the fact, as though we were not being transparent.

Appreciate that, a lot.

Particularly with software auto-updates, a software mute is simply untrustworthy.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by sib on Tuesday January 12, 2021 @04:16PM (#25753813)
True. And in the early (internal) alpha days, false positives for wake word detection were quite high. So we felt the pain from eating our own dogwood; even though we spent huge amount of science / engineering resources on reducing those false positives, we knew it would never get to zero while maintaining acceptable true positive rates.

This is a good point, I had suspected that the mute function was, in fact, implemented in software.

That they went ahead and implemented in hardware is encouraging. Someone over there took the feature seriously enough to take it this far. I am sure it added cost over a software-only solution.

I'm honestly not sure what the public response would be. I'm inclined to believe the revelation that the microphone is always on would not effect bottom line too much. Though maybe if a good meme campaign materialized people would join in on the public flagellation. But I bet more on people appetite for a public lynching than sacrificing their own convenience for long term considerations

They don't have a huge market lead if at all (i've seen conflicting reports) and there are 3rd party Alexa products that compete indirectly. Considering how many new devices they churn out and how cheap they are to replace, probs good to maintain public opinion for years

Amazon is so big that the loss of outraged users is a rounding error to them. Ford used to let cars off the line missing bolts. They're still here because their pockets are deep enough to wait until people forget.

To me it's unfathomable to have such a device around. I even feel uncomfortable with my neighbor having one (which I _hear him talking to).

I assume it's like reading the side effects of medication and think they are other people's problems somehow. How do people trade core privacy for setting the alarm or getting the weather report by voice command. I don't respect them. Same with off the shelf IP cameras in one's bedroom. Hello?

Air gapped speech recognition and FOSS, or this should never, ever become a thing.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by ballenf on Tuesday January 12, 2021 @08:32AM (#25746573)
I think the issue is one of the consumer's intent: are you buying a phone with a bunch of extra capabilities or a microphone hooked to a data center around the world? And that explicit decision is what is jarring to people who value privacy.

Of course they both have microphones hooked to data centers, but the Alexas/Echos are almost worthless without the microphone enabled. Many people I know have turned off listening for trigger words on their phone.

That being said, I have a HomePod that I have to manually press the touch button on top for it to listen. I use it for music, an occasional family conference call and occasional for generic assistant stuff like weather.

I tried a Google Home but couldn't get it configured in that mode -- listen on physical touch only (that was 3-4 years ago). And doubly couldn't get it setup without deep integration into a google account. The HomePod complains occasionally that it can't answer because it hasn't been personalized to an account, but is otherwise totally fine operating without access to my every inner thought (web/location history, etc.).

I'm just as concerned about every modern car essentially being a microphone hooked to a datacenter on wheels. And new TVs. And a few refrigerators and kids toys. And light switches. At least phones (well iPhones -- haven't used the last few Android versions) are easy to setup without listening enabled. And on iPhones it's opt-in during the setup process (the Siri checkbox is default on, but you are prompted to decide with no other confusing decisions on the screen at the same time).

What's the difference? You trust it not to listen without the button press, I trust it to not listen without the wake word. To think that the distinction is meaningful is wishful thinking.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by dunnevens on Tuesday January 12, 2021 @10:30AM (#25748099)
It's kinda meaningful. Wake words can be sometimes triggered by accident. Or by things like that commercial from a few years ago. A physical button press avoids all that.
Re:Amazon Echo Flex: Microphone mute button appears to be re... by thebean11 on Tuesday January 12, 2021 @02:35PM (#25752244)
So the worry is that it will be triggered accidentally and hear something you didn't intend it to, then that tiny, rarely occurring piece of data will be used against you?
Re:Amazon Echo Flex: Microphone mute button appears to be re... by ballenf on Tuesday January 12, 2021 @01:47PM (#25751482)
I just see listening for a trigger word as surveillance. Your (and your guests) every word is analyzed and at least temporarily saved somewhere outside your control.
Re:Amazon Echo Flex: Microphone mute button appears to be re... by StavrosK on Tuesday January 12, 2021 @05:42PM (#25755011)
It's analyzed on the device, which is not outside your control. Besides, how do you know the same isn't true of the physical button?
Re:Amazon Echo Flex: Microphone mute button appears to be re... by tshaddox on Tuesday January 12, 2021 @10:19AM (#25747971)
I’m not seeing the difference. If you already have the cell phone in your home, you might as well get the smart speaker if you want the convenience of voice controls for playing music, setting timers, etc.
Re:Amazon Echo Flex: Microphone mute button appears to be re... by cmiles74 on Tuesday January 12, 2021 @11:19AM (#25748918)
I don't think any consumer is buying a smart phone with the expectation (or intent) that it's recording them all the time, or sometimes, or at the behest of law enforcement, etc. They aren't really thinking about this when they buy a product like the Echo, either, I don't think. Also: a phone without a microphone will be of limited utility on calls. ;-)

The only way to be sure these devices aren't listening to you is to not have one at all. Or, as the person in this article did, take it apart and de-cap the chips to make sure.

In the case of smart phones, I think it's a mistake to assume that switching some of these functions off in the settings will actually have the desired effect: preventing the phone from recording audio without making the owner aware of this recording.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by cmiles74 on Tuesday January 12, 2021 @10:48AM (#25748405)
In my opinion, the difference is the amount of social pressure that is bearing down. Deciding to avoid products like the Echo and it's not a big deal. My mother-in-law will roll her eyes when I remind her we don't want for Christmas but it's not a big deal.

I can't really get away without having a cell phone. The slope has been slippery on this one; when I purchased my first smart phone this wasn't a big concern (but maybe it should have been). It's been several years and it's a bigger sacrifice, in my opinion, to give up a smart phone. Even if I wanted to, my employer might buy one for me, for instance.

I do think the expectation today is that everyone have a smart phone.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by KraftKacke on Tuesday January 12, 2021 @09:18AM (#25747168)
Yes, phones do have microphones too. The were a confidentiality risk even before becoming mobile. You also have piping running through your house, which could be tapped, you don't even need microphones, and the EM field emitted by your monitor can be read across the street. So why even care? Why should I encrypt anything, if I can't even prove not living in an all powerful simulation?

Back on topic, it's not a phones intended purpose to snitch on you, they usually do not listen into the room, without extremely malicious manipulation, and more so you simply can not realistically avoid having a phone in your reach, today. If I were talking business I would probably leave the phone outside too, for that matter, and I don't trust cheap communication hardware, either.

In real life drawing analogies by principle doesn't make for a good argument, most of the time, as life is adaptation and compromise, not a path through a logical circuit.

Do you honestly not see an obvious difference between a phone and an Amazon wired device intended to record and remotely analyze what's happening in the room?

I sure don't, from a security viewpoint. They are both cloud-connected microphones. Google is just as likely as Amazon to listen in surreptitiously. And my phone is 1000x more vulnerable to someone _other than_ Google listening in due to installable apps.

Do you honestly not see that there's no fundamental difference between the two? A CPU, ram, storage, wireless modems, microphones and a battery all running under software we don't control.

As far as intent, it's not possible to be sure about intent, you have to judge based on the information we have which is the features and capabilities of the device.

For me what made me give in was realising how useful the features would be in regards to ADHD, allowing for a new input modality that just straight up reduces the friction it takes for me to set a reminder.

It's routine that I will just leave an item and forget where it is several times a day that I take it almost for granted up until it causes me to be late going out the door. Now I can yell "Find my phone" (or wallet, keys, etc) and my phone is there. Yes I could go to my computer, go to the find my phone page, but there's just more friction and these issues happen to me all the time. The more things I link up to voice control, the more options I have in regards to accomplish a task, and sometimes voice is the most efficient means of going about it.

I can get entertainment like a podcast or music without a single screen being involved, which given that I inherently have low impulse control, is a nice separation of things. Or I can again, find my stuff without looking at any screens. Voice input can act as a lesser evil to screens.

Saying to just use FOSS and air gaps, because of how immature such solutions are, is effectively saying you shouldn't use these systems at all. The benefits of using the systems that exist today makes it so that the average person, like yourself, judge me less because I appear more punctual and less forgetful and more productive and better rested and so on. Being human, you are likely to disrespect me for being late and disorganized no matter what my excuse is, whereas you'll only disrespect me for using voice assistants if you know I'm using them, so it's a winning tradeoff. Just like how some will judge me for taking medication but only if they know I'm using it.

But I have Amazon smart speakers in every room (on their own network that can see the network my smart lights are on.) They're great. I don't worry about Amazon listening in.

We have options of either to trust the company or some other auditor. We can try getting some laws made to ensure honesty, but I personally don't like that route this early in the technology.

What we need a completely independent organisation like EFF to audit and certify basic guarantees around privacy/safety. The companies should also prefer this route as it would give take some heat off in EU/Congress without creating bureaucratic bottlenecks.

One problem I see that such an organisation can act as front for the cartel to prevent entry of new startups/players.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by Daho0n on Tuesday January 12, 2021 @05:39AM (#25744957)

You're right, but how to do it otherwise? With the camera, there is at least the option of installing a mechanical shutter that can be easily seen (and understood) by users. With audio, I can't think of any similar solutions at the top of my head.

Of course, technically, not even this hardwired circuit is complete proof that there is no trickery going on. If Amazon really wanted, they could simply hide a second mic at some other place inside the device.

I think the only solution that would really solve this was public auditing of the whole device.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by ehnto on Tuesday January 12, 2021 @09:36AM (#25747404)
I think we are at a point with electronics and connectivity that trust is all consumers really have. Your average joe isn't going to think too hard about how they work, and they also lack the skills to assess it themselves.

It's not a problem without prior art though, and other industries have had to find solutions such as certifications, regulatory bodies etc. Think of medicine, food, vehicle saftey standards and the like. I'm not an electrical engineer but I can trust my fridge to draw what it says it will, because I know it's been through the regulatory processes to get to market and be stickered with the 4 star energy rating.

I think at this point we might need a privacy and ethics regulator for technology, with a certification program.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by SilasX on Tuesday January 12, 2021 @09:24AM (#25747247)
This. It's why it's so important for laptops to permit a physical slider to block the integrated camera. It is a low-cost, low tech way to verify that the camera is not picking up usable images.

The real problem is that we don't have something analogous for microphones. The best we could do is some kind of humming device that you could turn on near the sensor that would drown out any noises it might otherwise pick up (and also be unobtrusive).

Re:Amazon Echo Flex: Microphone mute button appears to be re... by throwawayp123 on Tuesday January 12, 2021 @10:05AM (#25747796)
Well, a physical open/close switch that's in line with the microphone lead would do the same thing. But, obviously that would be assuming privacy needs are incorporated into the design. I would imagine this could be added on some older laptop models with more physical space(I'm thinking of older thinkpads), but it would be a non-trivial process of opening a case, adding a cut-out for a switch, etc.
Re:Amazon Echo Flex: Microphone mute button appears to be re... by SilasX on Tuesday January 12, 2021 @10:27AM (#25748059)
To be analogous, it would have to actually interfere with the thing-being-sensed. The idea is that it should work despite you having no knowledge, and being completely untrusting, of what shenanigans they might have regarding how it's wired up.

> It is a low-cost, low tech way to verify that the camera is not picking up usable images.

It is definitely not low cost.

In the hardware business, we count pennies. We count fractions of pennies with the costs of various components.

A shutter means at least one extra mechanical part, and a more complicated housing and increased assembly time at the factory.

You might look at a piece of plastic and think it is only a few pennies of plastic. But by the time you get it integrated into the product, and shipped out to consumers, it can add up to a dollar of cost. That really eats into the profits of low-margin hardware.

Only if enough consumers care about hardware shutters does it make business sense to include it. If most don't, and it is not a part of their buying decision making, then you're just throwing away money. Especially if it leads to increased post-sales tech support costs: ("My camera doesn't work! Is the shutter closed? Oh it is!").

Note that this is not an argument not to have hardware shutters. They are a good thing. But they come at a significant (to the final price) cost.

Re:Amazon Echo Flex: Microphone mute button appears to be re... by SilasX on Wednesday January 13, 2021 @11:46AM (#25764522)
I would consider it a non-standard usage of "low cost" to apply it to case of something that provides an important function for 1/1000th of the cost of the product.

In any case, I don't think that's relevant to my point: I specifically said "important for laptops to permit a physical slider to block the integrated camera". That phrasing was deliberate: you don't want to trust the OEM's slider in the first place, just be able to add you own.

So, am I addressing a strawman? What OEM impedes you from adding a slider? Well, actually, Apple says it's not recommended to use a webcam cover because of how they designed it. That is poor design and security practice.

Crucially, if the social work to buy trust does no exist, it entirely falls on you.

I consider myself that trusting the Echo (or other home assistance devices) is too much work for the meager benefit it provides.

I disagree with the idea that people, on average, take the word of business or corporate entities on faith. In the US we have organizations that vet drugs and medication (FDA) as well as to verify the safety of foods (USDA). I believe most US states license restaurants and have a process to ensure they aren't poisoning customers.

In my opinion, it's only in the case of electronic and software products where we are supposed to take so much functioning of the device on faith. Perhaps this is a bad idea and we need an organization to vet these products as well.

I'd want the source and the build chain for all the mcus on that board, you can turn many things into a microphone. I wouldn't put it past FAANG to get cute with it.
