AI wearable helps stroke survivors speak again

NEWYou can now listen to Fox News articles!

Losing the ability to speak clearly after a stroke can feel devastating. For many survivors, the words are still there in their minds, but their bodies will not cooperate. Speech becomes slow, unclear or fragmented. This condition, known as dysarthria, affects nearly half of all stroke survivors and can make everyday communication exhausting. Now, researchers believe they may have found a better way forward. Scientists at the University of Cambridge have developed a wearable device called Revoice. It is designed to help people with post-stroke speech impairment communicate naturally again without surgery or brain implants.

FULLY IMPLANTABLE BRAIN CHIP AIMS TO RESTORE REAL SPEECH

Why dysarthria makes recovery so hard

Dysarthria is a physical speech disorder. A stroke can weaken the muscles in the face, mouth and vocal cords. As a result, speech may sound slurred, slow or incomplete. Many people can only say a few words at a time, even though they know exactly what they want to say. According to professor Luigi Occhipinti, that disconnect creates deep frustration. Stroke survivors often work with speech therapists using repetitive drills. These exercises help over time, but open-ended conversation remains difficult. Recovery can take months or even longer, which leaves patients struggling during daily interactions with family, caregivers and doctors.

How the Revoice device works

Revoice takes a very different approach. Instead of asking users to type, track their eyes or rely on implants, the device reads subtle physical signals from the throat and neck. It looks like a soft, flexible choker made from breathable, washable fabric. Inside are ultra-sensitive textile strain sensors and a small wireless circuit board. When a user silently mouths words, the sensors detect tiny vibrations in the throat muscles. At the same time, the device measures pulse signals in the neck to estimate emotional state.

Those signals are processed by two artificial intelligence (AI) agents:

  • One reconstructs words from mouthed speech
  • The other interprets emotion and context to build complete sentences

Together, they allow Revoice to turn a few mouthed words into fluent speech in real time.

Why this AI approach is different

Earlier silent speech systems had serious limits. Many were tested only on healthy volunteers. Others forced users to pause for several seconds between words, which made the conversation feel unnatural. Revoice avoids those delays. It uses an AI-driven throat sensor system paired with a lightweight language model. Because the model runs efficiently, it uses very little power and delivers near-instant responses. The device is powered by a 1,800 mWh battery, which researchers expect will last a full day on a single charge.

What early trials revealed

After refining the system with healthy participants, researchers tested Revoice with five stroke patients who had dysarthria.

The results were striking:

  • Word error rate: 4.2%
  • Sentence error rate: 2.9%

In one example, a patient mouthed the phrase “We go hospital.” Revoice expanded it into a complete sentence that reflected urgency and frustration, based on emotional signals and context. Participants reported a 55% increase in satisfaction and said the device helped them communicate as fluently as they did before their stroke.

Beyond stroke recovery

Researchers believe Revoice could also help people with Parkinson’s disease and motor neuron disease. Because the device is comfortable, washable, and designed for daily wear, it could fit into real-world routines rather than being confined to clinics. Before that can happen, larger clinical trials are required. The research team plans to begin broader studies with native English-speaking patients and hopes to expand the system to support multiple languages and a wider range of emotional expressions. The findings were published in the journal Nature Communications.

What this means for you

If you or someone you care for has experienced a stroke, this research points to a major shift in recovery tools. Revoice suggests that speech assistance does not need to be invasive to be effective. A wearable solution could support communication during the most difficult months of rehabilitation, when confidence and independence often suffer the most. It may also reduce stress for caregivers who struggle to understand incomplete or unclear speech. Clear communication can improve medical care, emotional well-being and daily decision-making.

Kurt’s key takeaways

Communication is tied closely to dignity and independence. For stroke survivors, losing that ability can be one of the hardest parts of recovery. Revoice shows how artificial intelligence and wearable tech can work together to restore something deeply human. While it is still early, this device represents a meaningful step toward making recovery feel less isolating and more hopeful.

If a simple wearable could help restore natural speech, should it become a standard part of stroke rehabilitation? Let us know by writing to us at Cyberguy.com

HP ZBook Ultra G1a review: a business-class workstation that’s got game

HP ZBook Ultra G1a review: a business-class workstation that’s got game

Business laptops are typically dull computers foisted on employees en masse. But higher-end enterprise workstation notebooks sometimes get an interesting enough blend of power and features to appeal to enthusiasts. HP’s ZBook Ultra G1a is a nice example. It’s easy to see it as another gray boring-book for spendy business types, until you notice a few key specs: an AMD Strix Halo APU, lots of RAM, an OLED display, and an adequate amount of speedy ports (Thunderbolt 4, even — a rarity on AMD laptops).

I know from my time with the Asus ROG Flow Z13 and Framework Desktop that anything using AMD’s high-end Ryzen AI Max chips should make for a compelling computer. But those two are a gaming tablet and a small form factor PC, respectively. Here, you get Strix Halo and its excellent integrated graphics in a straightforward, portable 14-inch laptop — so far, the only one of its kind. That should mean great performance with solid battery life, and the graphics chops to hang with midlevel gaming laptops — all in a computer that wouldn’t draw a second glance in a stuffy office. It’s a decent Windows (or Linux) alternative to a MacBook Pro, albeit for a very high price.

$3499

The Good

  • Great screen, keyboard, and trackpad
  • Powerful AMD Strix Halo chip
  • Solid port selection with Thunderbolt 4
  • Can do the work stuff, the boring stuff, and also game

The Bad

  • Expensive
  • Strix Halo can be power-hungry
  • HP’s enterprise-focused security software is nagging

The HP ZBook Ultra G1a starts around $2,100 for a modest six-core AMD Ryzen AI Max Pro 380 processor, 16GB of shared memory, and basic IPS display. Our review unit is a much higher-spec configuration with a 16-core Ryzen AI Max Plus Pro 395, 2880 x 1800 resolution 120Hz OLED touchscreen, 2TB of storage, and a whopping 128GB of shared memory, costing nearly $4,700. I often see it discounted by $1,000 or more — still expensive, but more realistic for someone seeking a MacBook Pro alternative. Having this much shared memory is mostly useful for hefty local AI inference workloads and serious dataset crunching; most people don’t need it. But with the ongoing memory shortage I’d also understand wanting to futureproof.

  • Screen: A
  • Webcam: B
  • Keyboard: B
  • Trackpad: B
  • Port selection: B
  • Speakers: B
  • Number of ugly stickers to remove: 1 (only a Windows sticker on the bottom)

Unlike cheaper HP laptops I’ve tested that made big sacrifices on everyday features like speaker quality, the ZBook Ultra G1a is very good across the board. The OLED is vibrant, with punchy contrast. The keyboard has nice tactility and deep key travel. The mechanical trackpad is smooth, with a good click feel. The 5-megapixel webcam looks solid in most lighting. And the speakers have a full sound that I’m happy to listen to music on all day. I have my gripes, but they’re minor: The 400-nit screen could be a little brighter, the four-speaker audio system doesn’t sound quite as rich as current MacBook Pros, and my accidental presses of the Page Up and Page Down keys above the arrows really get on my nerves. These quibbles aren’t deal-breakers, though for the ZBook’s price I wish HP solved some of them.

The big thing you’re paying for with the ZBook Ultra is that top-end Strix Halo APU, which is so far only found in $2,000+ computers and a sicko-level gaming handheld, though there will be cut-down versions coming to cheaper gaming laptops this year.

The flagship 395 chip in the ZBook offers speedy performance for mixed-use work and enough battery life to eke out an eight-hour workday filled with Chrome tabs and web apps (with power-saving measures). I burned through battery in Adobe Lightroom Classic, but even though Strix Halo is less powerful when disconnected from wall power, the ZBook didn’t get bogged down. I blazed through a hefty batch edit of 47-megapixel RAW images without any particularly long waits on things like AI denoise or automated masking adjustments.

An understated workhorse of a laptop, for an opulent price.

An understated workhorse of a laptop, for an opulent price.

The ZBook stays cool and silent during typical use; pushing it under heavy loads only yields a little warmth in its center and a bit of tolerable fan noise that’s easily drowned out by music, a video, or a game at normal volume.

This isn’t a gaming-focused laptop any more than a MacBook Pro is, as its huge pool of shared memory and graphics cores are meant for workstation duties. However, this thing can game. I spent an entire evening playing Battlefield 6 with friends, with Discord and Chrome open in the background, and the whole time it averaged 70 to 80fps in 1920 x 1200 resolution with Medium preset settings and FSR set to Balanced mode — with peaks above 100fps. Running it at the native 2880 x 1800 got a solid 50-ish fps that’s fine for single-player.

Intel’s new Panther Lake chips also have great integrated graphics for gaming, while being more power-efficient. But Strix Halo edges out Panther Lake in multi-core tasks and graphics, with the flagship 395 version proving as capable as a laptop RTX 4060 discrete GPU. AMD’s beefy mobile chips have also proven great for Linux if you’re looking to get away from Windows.

In addition to Windows 11’s upsells and nagging notifications, the ZBook also has HP’s Wolf Security, designed for deployment on an IT-managed fleet of company laptops. For someone not using this as a work-managed device, its extra layer of protections may be tolerable, but they’re annoying. They range from warning you about files from an “untrusted location” (fine) to pop-ups when plugging in a non-HP USB-C charger (infuriating). You can turn off and uninstall all of this, same as you can for the bloatware AI Companion and Support Assistant apps, but it’s part of what HP charges for on its Z workstation line.

You don’t need to spend this kind of money on a kitted-out ZBook Ultra G1a unless you do the kind of specialized computing (local AI models, mathematical simulations, 3D rendering, etc.) it’s designed for. There’s a more attainable configuration, frequently on sale for around $2,500, but its 12-core CPU, lower-specced GPU, and 64GB of shared memory are a dip in performance.

Thunderbolt 4? On an AMD laptop?

Heresy! (I like heresy.)

If you’re mostly interested in gaming, an Asus ROG Zephyrus G14 or even a Razer Blade 16 make a hell of a lot more sense. For about the price of our ZBook Ultra review unit, the Razer gets you an RTX 5090 GPU, with much more powerful gaming performance, while the more modest ROG Zephyrus G14 with an RTX 5060 gets you comparable gaming performance to the ZBook Ultra in a similar form factor for nearly $3,000 less. The biggest knock against those gaming laptops compared to the ZBook is that their fans get much louder under load.

And while it’s easy to think of a MacBook Pro as the lazy answer to all computing needs, it still should be said: If you don’t mind macOS, you can get a whole lot more (non-gaming) performance from an M4 Pro / M4 Max MacBook Pro. Even sticking with Windows and integrated graphics, the Asus Zenbook Duo with Panther Lake at $2,300 is a deal by comparison, once it launches.

1/7

This keyboard is excellent.

At $4,700, this is a specific machine for specialized workloads. It’s a travel-friendly 14-inch that can do a bit of everything, but it’s a high price for a jack of all trades if you’re spending your own money. The ZBook piqued my interest because it’s one of the earliest examples of Strix Halo in a conventional laptop. After using it, I’m even more excited to see upcoming models at more down-to-earth prices.

Warm-skinned AI robot with camera eyes is seriously creepy

Warm-skinned AI robot with camera eyes is seriously creepy

NEWYou can now listen to Fox News articles!

Humanoid robots are no longer hiding in research labs somewhere. These days, they are stepping into public spaces, and they are starting to look alarmingly human. 

A Shanghai startup has now taken that idea further by unveiling what it calls the world’s first biometric AI robot. Yes, it is as creepy as it sounds. The robot is called Moya, and it comes from DroidUp, also known as Zhuoyide. The company revealed Moya at a launch event in Zhangjiang Robotics Valley, a growing hotspot for humanoid development in China. 

At first glance, you can still tell Moya is a robot. The skin looks plasticky. The eyes feel vacant. The movements are slightly off. Then you learn more details about her, and that’s when the discomfort kicks in.

Warm skin makes this humanoid robot feel unsettling

HUMANOID ROBOTS ARE GETTING SMALLER, SAFER AND CLOSER

Even when standing still, the robot’s posture and proportions blur the line between machine and person in a way many people find unsettling.  (DroidUp)

Most robots feel cold and mechanical. Moya does not. According to DroidUp, Moya’s body temperature sits between 90°F and 97°F, roughly the same range as a human. Company founder Li Qingdu says robots meant to serve people should feel warm and approachable. That idea sounds thoughtful until you picture a humanoid with warm skin standing next to you in a quiet hallway. DroidUp says this design points toward future use in healthcare, education and commercial settings. It also sees Moya as a daily companion. That idea may excite engineers. However, for many people, it triggers the opposite reaction. Warmth removes one of the few clear signals that separates machines from humans. Once that line blurs, discomfort grows fast.

Why this humanoid robot’s walk feels so off

Moya does not roll or glide. She walks. DroidUp says her walking motion is 92 percent accurate, though it is not clear how that number is calculated. On screen, the movement feels cautious and a little stiff. It looks like someone is moving carefully after leg day at the gym. The hardware underneath is doing real work. Moya runs on the Walker 3 skeleton, an updated system connected to a bronze medal finish at the world’s first robot half-marathon in Beijing in April 2025. Put simply, robots are getting better at moving through everyday spaces. Watching one do it this convincingly feels strange, not impressive. It makes you stop and stare, then wonder why it feels so uncomfortable.

Camera eyes and facial reactions raise privacy concerns

Behind Moya’s eyes sit cameras. Those cameras allow her to interact with people and respond with subtle facial movements, often called microexpressions. Add onboard AI and DroidUp now labels Moya a fully biomimetic embodied intelligent robot. That phrase sounds impressive. It also raises obvious questions. If a humanoid robot can see you, track your reactions and mirror emotional cues, trust becomes complicated. You may forget you are interacting with a machine. You may act differently. That shift has consequences in public spaces. This is AI moving out of screens and into physical proximity. Once that happens, the stakes change.

Price alone keeps this robot out of your home

If you are worried about waking up to a warm-skinned humanoid in your home, relax for now. Moya is expected to launch in late 2026 at roughly $173,000. That price places her firmly in institutional territory.  DroidUp sees the robot working in train stations, banks, museums and shopping malls. Tasks would include guidance, information and public service interactions. That still leaves plenty of people uneasy, especially those whose jobs already feel vulnerable to automation. For homes, the future still looks more like robot vacuums than walking companions.

Up close, Moya’s eyes look almost human, which raises questions about how much realism is too much for robots meant to operate in public spaces.  (DroidUp)

WORLD’S FIRST AI-POWERED INDUSTRIAL SUPER-HUMANOID ROBOT

What this means to you

This is not about buying a humanoid robot tomorrow. It is about where technology is heading. Warm skin, camera eyes and human-like movement signal a shift in design priorities. Engineers want robots that blend in socially. The more they succeed, the harder it becomes to maintain clear boundaries. As these machines enter public spaces, questions about consent, surveillance and emotional manipulation will follow. Even if the robot is polite and helpful, the presence alone changes how people behave. Creepy reactions are not irrational. They are early warning signs.

Kurt’s key takeaways

Moya’s debut feels worth paying attention to because she is real enough to trigger discomfort almost instantly. That reaction matters. It suggests people are being asked to get used to lifelike machines before they have time to question what that really means. Humanoid robots do not need warm skin to be helpful. They do not need faces to point someone in the right direction. Still, companies keep pushing toward realism, even when it makes people uneasy. In tech, speed often comes before reflection, and this is one area where slowing down might matter more than racing ahead.

If a warm-skinned robot with camera eyes greeted you out in public, would you trust it or avoid eye contact and walk faster? Let us know by writing to us at Cyberguy.com.

Moya’s humanlike appearance is intentional, from her warm skin to subtle facial details designed to feel familiar rather than mechanical.   (DroidUp)

Two more xAI co-founders are among those leaving after the SpaceX merger

Two more xAI co-founders are among those leaving after the SpaceX merger

Since the xAI-SpaceX merger announced last week, which combined the two companies (as well as social media platform X) for a reported $1.25 trillion valuation — the biggest merger of all time — a handful of xAI employees and two of its co-founders have abruptly exited the company, penning long departure announcements online. Some also announced that they were starting their own AI companies.

Co-founder Yuhai (Tony) Wu announced his departure on X, writing that it was “time for [his] next chapter.” Jimmy Ba, another co-founder, posted something similar later that day, saying it was “time to recalibrate [his] gradient on the big picture.” The departures mean that xAI is now left with only half of its original 12 co-founders on staff.

It all comes after changing plans for the future of the combined companies, which Elon Musk recently announced would involve “space-based AI” data centers and vertical integration involving “AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.” Musk reportedly also talked of plans to build an AI satellite factory and city on the moon in an internal xAI meeting.

Musk wrote on X Wednesday that “xAI was reorganized a few days ago to improve speed of execution” and claimed that the process “unfortunately required parting ways with some people,” then put out a call for more people to apply to the company. He also posted a recording of xAI’s 45-minute internal all-hands meeting that announced the changes.

“We’re organizing the company to be more effective at this scale,” Musk said during the meeting. He added that the company will now be organized in four main application areas: Grok Main and Voice, Coding, Imagine (image and video), and Macrohard (“which is intended to do full digital emulation of entire companies,” Musk said).
