back to article Solder and Lego required: The Register builds glorious Project Alias gizmo to deafen Alexa

Readers, we asked you what materials we should use to construct homebrew gadget Project Alias – which deafens smart speakers – and a whopping 40 per cent of you demanded Lego. When we first looked at Project Alias at the beginning of February, we liked it – though we did question why someone would buy a smart speaker if …

    If I was to have one

    It would only be acquired after I was convinced it wouldn't be trying to listen on me... and I found a use-case that I really need it for.

    My heating system is designed to maintain constant temperature, so no turning it on or off, my lights have switches in useful places so I can toggle them as I walk into / out of rooms, and I even have an extra switch by the bed, avoiding the issues of avoiding debris getting to/from the bed in the dark.

    I could get it to play music, but I have a good sound system linked up to a computer that can do all that, controlled either by a controller or a wireless keyboard with it's own trackpad for easy remote access.

    As much as I'm a bit of a geek and like cool tech, I'm also practical about it. And really, something that avoids my needing to get off my rear every once in a while is something that I probably don't need.

      Re: If I was to have one

      This 100%.

      We had some friends over at the weekend who were selling the virtues of Nest heating controllers and to say I remain unconvinced is an understatement. Utterly pointless vs the cost and risk, but hey ho each to their own. Fifty quid for remote LEDs for the light fittings. Eh?

      Although as the link posted further up, I did have fun over Christmas dropping all sorts of things into conversation to see what their targeted ads Alexa would start to show. Eventually she insisted I stopped but couldn't explain why, even though she was adamant it does not listen, as the panic and worry started to build.

        As a caregiver google home is great. It takes a lot stress off of me when I am gone. It connects to the Nest thermostat so if my sister is having a bad day she can change the temperature in the house from her bedroom. I can also check the smoke and carbon monoxide sensors from my phone. Next is the doorbell camera so she can see who the dogs are barking at.

        If I didn't need it to take care of my sister it wouldn't be in my house.

              It also generally works out cheaper in the long run to buy a system like this rather than building your own, running in the necessary cables, tweaking it when it doesn't quite work properly and eventually giving up and buying the commercial version anyway.

            "You could DYI some kit to do this without going thru Google or Amazon..."

            But none of it is as easy to use for the end user. I've had a good look and nothing replaces the ease and simplicity of adding stuff to the Alexa setup we have at home. We can check all sorts of things now: has the morning carer left the shower and heater on? Have they left any lights on? What's the temp in the important rooms? All sorts.

            That's only the bits for us - our relative can do many things she simply couldn't do before. She can turn on a light switch - but the switch on the wall doesn't to table lamps - she prefers these. Alexa does the table lamps. She can tell them to turn on. It's things like this that help you feel human.

            When you are a carer, live upstairs and are heading to your 50s then going up and down stairs dozens of times a day is a drag.

            Sometimes you want ease, cheapness and simplicity - Alexa gives us all 3. I couldn't care less if Amazon knows when I turn the lights on!

          Re: If I was to have one

          You obviously have no idea how exhausting caring for someone you love who is struggling can be. I had a small taste of this when my wife was wheelchair bound for 9 weeks after a car crash, re-arranging the house so she could come home from hospital was exhausting enough. We were extremely fortunate that we got 3 carers visits per day while I was at work but, I was still having to get up at dawn, get to work later (so leave later in the evening) then come home pick up the housework and additional care for the evening and then get her to bed. Fitting in shopping for food doing the washing etc and making sure we got out of the house for at least a short trip each weekend pretty much filled my waking hours. An off the shelf solution which just works like nest is a godsend for some carers and getting involved in petty criticism is not helpful. I'm sure the original contributer weighed up the privacy concerns but in this situation I would do exactly the same. If I ad 2 --3 hours spare I would rather have spent it ensuring my wife had a little fun rather than fiddling with tech bits. I do have privacy concerns about this tech and don't use Google Assistant, Cortana or Siri and do not have smart speakers but do use google audio and video Chromecasts as they are extending the life of several thousand pounds worth of hifi and TV equipment.

            I've been caring for someone since before any of this stuff was available. There are loads of practical solutions available. An occupational therapist or social worker or whoever they send these days can advise you and may even organise getting it fitted if our political lords and masters haven't decided that pay rises for MPs are more imprtant than this kind of thing.

              I call BS on your claim of caring for anyone - certainly not recently. If you had any level of current care for anyone you wouldn't mention asking social services for help. They have less than no budget nowadays and are therefore less than useless.

                Call BS all you like, it's still the truth. Soical Services have always been crap but we did get some ideas from them. Most things we had to pay for ourselves but there was a little help for some items.

                As the years went by I also came to realise that filling the forms out in the "right" way made a big difference. There were often certain thresholds which triggered help. The forms often don't recognise that health conditions fluctuate so 50 steps one day may not be possible the next day or might lead to the next two days in bed recovering.

                It's a horrible process, demeaning, depressing... it makes the person effected have to repeat over and over again all the things they can't do which isn't good for their psychology. Any hint of being positive means you won't get the help you need.

          A system like that was recently installed at the home of an elderly person. It cost less in rental over 3 years that the nest kit.

          Plus they have humans available 24x7 who can call for the fire brigade or an it has a pendant or wrist strap with a button the can push for help.

          It's just the local council's carline service.

        Re: Nest controllers

        If anyone had told your friends, or they themselves had done some homework, they would have discovered that Nest devices only work when it has internet access - once their internet is down, you have no manual control of the system, even manually from the device itself. It is locked into the last setting until it gets internet again.

        In Amerika we have the Honeywell controllers, which are autonomous with internet control added, rather than internet devices with manual convenience controls.

        So, as usual, the most-known, popular device is the worst choice for an individual's continued independence.

          Re: Nest controllers

          I did not know this, but I doubt I'll share it with them; I'd hate to come over as ridiculing their decisions anymore than I already have.

          I am somewhat amazed at this though. Clearly I appreciate if the net goes down the connection is lost for remote access, but I would have assumed access via the internal wifi network would still be granted. Evidently that is not the case.

    Of course there's a way cooler thing do do

    Write some little speech synthesis software which can "morph" in between different sentences. Then you start off by making it say some un common phrase like "Alexa, buy a pine". When it answers correctly you change it slightly towards something more usual like "Alexa, what's the time". When it answers incorrectly you go back a bit.

    Done with a bit more finesse and ideally more devices, it should be possible to train it to miss-hear more and more phrases, probably even for other users, as it'll try to track the change in pronounciation.

    Why not put in a packet filter that cuts out all traffic back to Amazon unless you utter the magic phrase.

    I mean its wireless but it has to go to your wi-fi router which then goes to your network where you can do real time packet filtering.

    And instead of just dropping them... see what they contain. ;-)

          Breaking the handshake would only stop the communication; it wouldn't enable you to see what they were sending. Unless you can install your own root CA / private key on the device, but if you can do that then you probably wouldn't bother with a network-based MITM

    "As for the "Did it work?" part: yes, it did. Kind of. Our assembly may have lacked elegance but it did the trick. Sadly the key phrase wasn't always recognised, and the thing was easily flummoxed by background noise, but the makers acknowledge that more training is needed to bring the machine learning models up to speed, and they hope the community will get involved."

    Sounds like every single "voice recognition" tool I've ever used in my entire life.

    But I can't see why you'd go to the effort of baffling Alexa with lots of other gadgets when you could just use the thing you have that recognises voice commands (as well as anything else) and make your own smart assistant. I'm sure there must be a project somewhere already, if not a dozen of them. And with something like OpenHAB, you could easily make it control anything you liked. Even Alexa/Home-compatible devices.

    We're technical sorts, not Luddites

    I don't understand this 'bash the kit' mindset. If you don't like the things don't buy them. If you do have one or more then there are plenty of ways to neuter them if you want, anything from using their 'mute' button to just unplugging them. (The mute button, which I notice nobody has mentioned, switches off the microphones. The interface shows an angry red ring -- my wife says that ladies don't like being ignored.) They represent a huge advance in computer peripherals, something that makes a generic sci-fi movie from a year or so back look really dated. As technical people we should be delving into the technology, understanding its capabilities and limitations and learning how to work with it....not necessarily the Amazon flavor but as a generic technology.

    Oh yes, while we're on the subject of Big, Bad, Corporations I notice a lot of articles about cloud computing, containers and the like. Doesn't everyone know where this stuff is really running? Amazon, for example, might like to sell us everything in the world but where they really make money is AWS.
