The Voice Of ChatGPT Is Now On The Air

AIs can now apparently carry on a passable conversation, depending on what you classify as passable conversation. The quality of your local pub’s banter aside, an AI stuck in a text box doesn’t have much of a living quality. human. An AI that holds a conversation aloud, though, is another thing entirely. [William Franzin] has whipped up just that on amateur radio.  (Video, embedded below.)

The concept is straightforward, if convoluted. A DSTAR digital voice transmission is received, which is then transcoded to regular digital audio. The audio then goes through a voice recognition engine, and that is used as a question for a ChatGPT AI. The AI’s output is then fed to a text-to-speech engine, and it speaks back with its own voice over the airwaves.

[William] demonstrates the system, keying up a transmitter to ask the AI how to get an amateur radio licence. He gets a pretty comprehensive reply in return.

The result is that radio amateurs can call in to ChatGPT with questions, and can receive actual spoken responses from the AI. We can imagine within the next month, AIs will be chatting it up all over the airwaves with similar setups. After all, a few robots could only add more diversity to the already rich and varied ham radio community. Video after the break.

Hackaday Links: January 22, 2023

The media got their collective knickers in a twist this week with the news that Wyoming is banning the sale of electric vehicles in the state. Headlines like that certainly raise eyebrows, which is the intention, of course, but even a quick glance at the proposed legislation might have revealed that the “ban” was nothing more than a non-binding resolution, making this little more than a political stunt. The bill, which would only “encourage” the phase-out of EV sales in the state by 2035, is essentially meaningless, especially since it died in committee before ever coming close to a vote. But it does present a somewhat lengthy list of the authors’ beefs with EVs, which mainly focus on the importance of the fossil fuel industry in Wyoming. It’s all pretty boneheaded, but then again, outright bans on ICE vehicle sales by some arbitrary and unrealistically soon deadline don’t seem too smart either. Couldn’t people just decide what car works best for them?

Speaking of which, a man in neighboring Colorado might have some buyer’s regret when he learned that it would take five days to fully charge his brand-new electric Hummer at home. Granted, he bought the biggest battery pack possible — 250 kWh — and is using a standard 120-volt wall outlet and the stock Hummer charging dongle, which adds one mile (1.6 km) to the vehicle’s range every hour. The owner doesn’t actually seem all that surprised by the results, nor does he seem particularly upset by it; he appears to know enough about the realities of EVs to recognize the need for a Level 2 charger. That entails extra expense, of course, both to procure the charger and to run the 240-volt circuit needed to power it, not to mention paying for the electricity. It’s a problem that will only get worse as more chargers are added to our creaky grid; we’re not sure what the solution is, but we’re pretty sure it’ll be found closer to the engineering end of the spectrum than the political end.

Giving An Old Typewriter A Mind Of Its Own With GPT-3

There was an all-too-brief period in history where typewriters went from clunky, purely mechanical beasts to streamlined, portable electromechanical devices. But when the 80s came around and the PC revolution started, the typewriting was on the wall for these machines, and by the 90s everyone had a PC, a printer, and Microsoft Word. And thus the little daisy-wheel typewriters began to populate thrift shops all over the world.

That’s fine with us, because it gave [Arvind Sanjeev] a chance to build “Ghostwriter”, an AI-powered automatic typewriter. The donor machine was a clapped-out Brother electronic typewriter, which needed a bit of TLC to bring it back to working condition. From there, [Arvind] worked out the keyboard matrix and programmed an Arduino to drive the typewriter, both read and write. A Raspberry Pi running the OpenAI Python API for GPT-3 talks to the Arduino over serial, which basically means you can enter a GPT writing prompt with the keyboard and have the machine spit out a dead-tree version of the results.

To mix things up a bit, [Arvind] added a pair of pots to control the creativity and length of the response, plus an OLED screen which seems only to provide some cute animations, which we don’t hate. We also don’t hate the new paint job the typewriter got, but the jury is still out on the “poetry” that it typed up. Eye of the beholder, we suppose.

Whatever you think of GPT’s capabilities, this is still a neat build and a nice reuse of otherwise dead-end electronics. Need a bit more help building natural language AI into your next project? Our own [Donald Papp] will get you up to speed on that.

AI-Controlled Twitch V-Tuber Has More Followers Than You

Surely we have all at least heard of Twitch by now. For the as-yet uninitiated: imagine you had your own TV channel. What would you do on it? Although Twitch really got going as a place for gamers to stream the action, there are almost as many people jamming out on their guitars, or building guitars, or just talking about guitars. And that’s just the example that uses guitars — if you can think of it, someone is probably doing it live on Twitch, within the Terms of Service, of course.

Along with the legions of people showing their faces and singing their hearts out, you have people in partial disguise, and then you have v-tubers. That stands for virtual tubers, and it just means that the person is using an anime avatar to convey themselves.

Now that you’re all caught up, let’s digest the following item together: there’s a v-tuber on Twitch that’s controlled entirely by AI. Let me run that by you again: there’s a person called [Vedal] who operates a Twitch channel. Rather than stream themselves building Mad Max-style vehicles and fighting them in a post-apocalyptic wasteland, or singing Joni Mitchell tunes, [Vedal] pulls the strings of an AI they created, which is represented by an animated character cleverly named Neuro-sama. Not only does Neuro-sama know how to play Minecraft and osu!, she speaks gamer and interacts regularly with chat in snarky, 21st century fashion. And that really is the key behind Twitch success — interacting with chat in a meaningful way.

Can AI Replace Your DM?

The current hotness is anything to do with artificial intelligence, and along with some interesting experiments comes a lot of mindless hype. The question is, what can it do for us! [Jesse] provides a fun answer by asking ChatGPT to perform as a Dungeons and Dragons dungeon master.

There are many ways to approach a game of D&D, and while some take the whole thing very seriously indeed we prefer to treat it as a lightly inebriated band of intrepid heroes smacking each other and assorted monsters with imaginary swords and war hammers. Would the AI follow the nerdiest cliches to their pedantic conclusions, or would it sense that the point of a game is to have fun?

Holographic Cellphones Coming Thanks To AI

Issac Asimov foresaw 3D virtual meetings but gave them the awkward name “tridimensional personification.” While you could almost do this now with VR headsets and 3D cameras, it would be awkward at best. It is easy to envision conference rooms full of computer equipment and scanners, but an MIT student has a method that may do away with all that by using machine learning to simplify hologram generation.

As usual, though, the popular press may be carried away a little bit. The key breakthrough here is that you can use TensorFlow to generate real-time holograms at a few frames per second using consumer-grade processing power found in a high-end phone from images with depth information, which is also available on some phones. There’s still the problem of displaying the hologram on the other side, which your phone can’t do. So any implication that you’ll download an app that enables holograms phone calls is hyperbole and images of this are in the realm of photoshop.

3D Modelling In English With AI

By now, you’ve surely seen the AI tools that can chat with you or draw pictures from prompts. OpenAI now has Point-E, which takes text or an image and produces a 3D model. You can find a few runnable demos online, but good luck having them not too busy to work.

We were not always impressed with the output. Asking for “3d printable starship Enterprise,” for example, produced a point cloud that looked like a pregnant Klingon battle cruiser. Like most of these tools, the trick is finding a good prompt. Simple things like “a chair” seemed to work somewhat better.
