DIY Communication Devices

Advertisements

Disclaimer: This is about a communication device that Anne helped me set up as a backup communication device (all my other backups — mostly bought used, some bought broken to replace parts in dead ones — have by now long since died or otherwise become unusable by me). Make one of these things at your own risk. Before you buy it, look into it more, understanding that so far neither Anne nor I have figured out how to get full functionality out of the software, and that it involves various vaguely techie stuff like looking for DLL files to download and stick in the right directories and stuff, or the thing simply will not work at all. And this device may be totally unusable to some people for a number of reasons that have to do with the size and shape of the machine, input accepted, etc. It’s not a replacement for a primary communication device either, but an excellent backup for some people, and for other it might be what they’d have to settle for until and unless they got something better.

Anyway, none of my backups work well enough for me to use at the moment (most don’t work at all), and even my main communication device is well-nigh impossible to use with the telephone in my house because of pesky things like logistics, priorities, and the laws of physics.

But I thought this sort of thing would be useful for anyone who has speech difficulties, whether it’s a physical thing, a cognitive thing, an emotional thing, or whatever. Anne said she’s thinking of publishing a guide on putting one of these things together, and that sounds like a good idea to me.

The best part about this is that all the parts can be found used and/or refurbished. This is a good thing because a huge number of disabled people are one or more of the following:

So basically, not everyone can get a device. This isn’t a perfect solution because it still costs money and not everyone has money. But something you can get for anything between $100-400 depending on where you get things and how lucky you get, is still better than getting a worse device for $2000 (yes, I have seen far worse for that amount of money).

The parts are:

And here’s the result:

My hands are there for size comparison, though the angle can make that confusing. Be aware I have small hands.

I have not yet got a video for it, and don’t hold your breath waiting, I haven’t been good at making videos lately at all.

Anyway, the plus side so far (some of these would be drawbacks for other people):

The portability. Sometimes I don’t have the energy, time, and/or inclination to lug a Dynavox around.

The size. Which is the reason I can’t use the Dynavox on the phone at the moment with other logistics and priorities within my apartment. Practically the moment I got this thing together, I had to make a pretty high-priority phone call to one of those services that calls you back later. I hadn’t been able to take those calls by myself in ages. So I didn’t get it a moment too soon.

The battery life seems pretty long so far. I have heard it’s longer on a 720 than on a 728, presumably because the 728 has more memory (AFAIK the only difference between the two). I haven’t had time to test this.

Keyboard size. I have tendonitis and not having to move my hands as far is really helpful. (I can’t imagine ten-finger touch-typing on this with large hands, I’m not even sure whether people with average-sized hands can do it or not.)

The shallow and light keys. The combination of tendonitis and hypermobility makes me dislike any key that’s hard to press. These are very easy to press. (Which might be a pain for someone who wants a lot of tactile feedback when the buttons are pushed.)

The minus side so far:

Some of the menus cut off halfway down, Anne and I have not figured out a way around it. (If anyone is willing to help us find something that allows us to either scroll the desktop down past the bottom of the screen, or take an already-running program and wrap anything going off the bottom of the screen onto the top of the screen, let one of us know. If anyone’s able to program a better-suited either cheap or freeware frontend to the Cepstral voices with the same functoinality, also let us know. This, among other things, is preventing us from saving our voice configurations, we have to slow down the voices and (in my case) lower them a little, every single time.)

The external speaker is hard to turn on and off, due to having to grab it and twist in a very particular way. It seems like it could break easily too, and it’s gotten stuck in between on and off several times.

The DLLs were a pain to get, both of us had to do them from scratch. We might provide better information on that later.

I don’t know that this will be a problem for me or not yet, but I’m not sure how durable this thing is. I no longer fling communication devices at walls or bash them on my head, but I’m still given to forgetting I have a hand, and consequently dropping things as my hand reverts to neutral or fails to correct for some other movement.

I haven’t figured out a way to mount it to my wheelchair yet, let alone at the right height. I wonder whether cannibalizing a mount-plate would be feasible, or whether that’d introduce other problems (it’d have to be able to come on and off even the mountplate quickly, because it has a USB cradle it has to fit into for charging and communication with my computer). Don’t know yet.

I have not yet gotten Ubuntu linux to recognize the Jornada as even existing, let alone talking to it. Still working on it. Haven’t yet tried using wine, I just booted to windows altogether.

I have also not yet tried finding the equipment to plug one into the phone directly. You can buy a thing from Radio Shack for about $15ish IIRC, that is meant for recording telephone calls with and playing tapes back over the phone. You connect it to the phone, flip it into “play” instead of “record”, plug it into the headphone port of the device, and you have a real (if sometimes awkward and ungainly) means of using a device’s sound output directly into the telephone. Depending on the situation an amplifier might also be necessary in between the communication device and the previous doohickey I just explained (I don’t know the word for them).

Anyway, I’m very happy with it so far despite its shortcomings, and looking forward to being able to improve on it. I am sure many variations on the same theme can be made, some of them more cheaply than this, some more expensively. Cepstral is a great source of cheap voices. Joel has made JTalk software to be used with different voices, on a different platform. Neither his nor Anne’s projects are intended to replace a person’s primary mode of communication, there’s too much that could go wrong that way. But as a backup or supplement to another means of communication, they can be excellent, and I’m very happy with it.
