A 16-Year-Old Builds a Device To Convert Breath Into Speech

stephendavion writes A 16-year-old from India has designed a device that converts breath into speech. High-school student Arsh Shah Dilbagi invented TALK as a portable and affordable way to aid people suffering from ALS, locked-in syndrome, and anyone else speech-impaired or paralyzed. Prototyped using a basic $25 Arduino microcontroller, Dilbagi's invention costs only $80, or about a hundred times less than the sort of Augmentative and Alternative Communication device used by Stephen Hawking. TALK works by translating breath into electric signals using a MEMS Microphone, an advanced form of listening tech that uses a diaphragm etched directly onto a silicon microchip. The user is expected to be able to give two distinguishable exhales, varying in intensity or time, so that they can spell words out using Morse code.

    Off the top of my head, I think this device would be slow to use, and would require a fair amount of skill/education (you have to be able to spell words in morse code - fine for many, but a problem if you've got broad developmental issues). Physically, for many users, taking 15 breaths to spell a word is going to be slow and (for some) very tiring. As you get tired and aren't in perfect control of your breathing, even small errors in input would cascade down and the resulting words would be unintelligible. Because Morse code isn't actually well suited to the task.

    Again, off the top of my head, it seems like it'd be much faster to choose common words (or pictures) off a screen (a screen wouldn't add much to the cost - probably only a few dollars). Then you could use continuous breaths - perhaps with the device measuring breath velocity when the user is able to moderate that - to alternatively move a cursor x+y (and then a short breath to "click") to choose options off a grid. With some training, I bet you could get most common words in 3 breaths this way. Or, when more choices are required, you could use the same mechanism to press keys on a keyboard (though, again, you'd definitely want word completion). For heavy users without developmental issues and with good breath control, you could build out a shorthand type system that might be fast enough for reasonably paced conversation (using breath length/intensity, and lengths of pauses between).

    I'm not saying this isn't a cool thing, and it could certainly be made cheaply (though, again, a very cheap screen would make this a lot easier to use). But it's pretty much the "hello world" of assistive devices. I like when people make new things, and I like effort/attention going to problems like this, but I'm tired of how these articles tend to belittle the work done by others who've approached the same problem. It's not that nobody ever thought of making a simple breath control system before. Most likely everyone who approached the problem started by making a device much like this to test the initial breath control... and then they made fancier ones that worked better, based on the feedback they got from real users. Pretty much any suitable engineer, when presented with this problem and a cost constraint, would be able to make a similar or more usable device.

  19. *Parts cost* is $80 (maybe). by Anonymous Coward · · Score: 0

    For the prototype. With the first cut user interface.
    The real deals cost thousands because
    a) they've had to go through a few more design iterations to actually be usable by lots of people
    b) they have to actually pay someone to assemble and test them
    c) they have to pay someone to put up the cash needed to build them in the first place
    d) they have to pay someone to sell and support them.

    A usual rule of thumb is that "sell price is 10x parts cost" for a "ready to go" device, which this isn't.
