This Lip-Syncing Robot Face Could Help Future Bots Talk Like Us

If we’re going to live and work with humanoid robots, maybe they should talk like humans, too.

The slight unease that creeps up your spine when you see something that acts human but isn’t remains a big issue in robotics — especially for robots built to look and speak like us.

That peculiar feeling is called the uncanny valley. One way roboticists work to bridge that valley is by matching a robot’s lip movements with its voice. On Wednesday, Columbia University announced research that delves into how a new wave of robot faces can speak more realistically.

Hod Lipson, a Columbia engineering professor who worked on the research, told CNET that a main reason why robots are «uncanny» is they don’t move their lips like us when they talk. «We are aiming to solve this problem, which has been neglected in robotics,» Lipson said.

This research comes as hype has been spiking around robots designed for use at home and work. At CES 2026 last week, for instance, CNET saw a range of robots designed to interact with people. Everything from the latest Boston Dynamics Atlas robot to household robots like those that fold laundry, and even a turtle-shaped bot designed for environmental research, made appearances at the world’s biggest tech show. If CES is any indication, 2026 could be a big year for consumer robotics.

Central among those are humanoid robots that come with bodies, faces and synthetic skin that mimics our own. The CES cohort included human-looking robots from Realbotix that could work information booths or provide comfort to humans, as well as a robot from Lovense designed for relationships that’s outfitted with AI to «remember» intimate conversations.

But a split-second mismatch between lip movement and speech can mean the difference between a machine that you can form an emotional attachment to and one that’s little more than an unsettling animatronic.

So if people are going to accept humanoid robots «living» among us in everyday life, it’s probably better if they don’t make us mildly uncomfortable whenever they talk.

Lip-syncing robots

To make robots with human faces that speak like us, the robot’s lips must be carefully synced to the audio of its speech. The Columbia research team developed a technique that helps robot mouths move like ours do by focusing on how language sounds.

First, the team built a humanoid robot face with a mouth that can talk — and sing — in a way that reduces the uncanny valley effect. The robot face, made with silicone skin, has magnet connectors for complex lip movements. This enables the face to form lip shapes that cover 24 consonants and 16 vowels.

To match the lip movements with speech, they designed a «learning pipeline» to collect visual data from lip movements. An AI model uses this data for training, then generates reference points for motor commands. Next, a «facial action transformer» turns the motor commands into mouth motions that synchronize with audio.

Using this framework, the robot face, called Emo, was able to «speak» in multiple languages, including languages that weren’t part of the training, such as French, Chinese and Arabic. The trick is that the framework analyzes the sounds of language, not the meaning behind the sound.

«We avoided the language-specific problem by training a model that goes directly from audio to lip motion,» Lipson said. «There is no notion of language.»

Why does a robot even need a face and lips?

Humans have been working alongside robots for a long time but they have always looked like machines, not people — the disembodied and very mechanical-looking arms on assembly lines or the chunky disc that is a robot vacuum scooting around our kitchen floors.

However, as the AI language models behind chatbots have become more prevalent, tech companies are working hard to teach robots how to communicate with us using language in real time.

There’s a whole field of study called human-robot interaction that examines how robots should coexist with humans, physically and socially. In 2024, a study out of Berlin that used 157 participants found that a robot’s ability to express empathy and emotion through verbal communication is critical for interacting effectively with humans. And another 2024 study from Italy found that active speech was important for collaboration between humans and robots when working on complex tasks like assembly.

If we’re going to rely on robots at home and at work, we need to be able to converse with them like we do with each other. In the future, Lipson says, research with lip-syncing robots would be useful for any kind of humanoid robot that needs to interact with people.

It’s also easy to imagine a future where humanoid robots are identical to us. Lipson says careful design could ensure that people understand they’re talking to a robot, not a person. One example would be requiring humanoid robots to have blue skin, Lipson says, «so that they cannot be mistaken for a human.»

ChatGPT Has a New Language Translation Option for You

It’s like Google Translate, but ChatGPT.

OpenAI is putting Google Translate on notice: It now has a dedicated ChatGPT Translate webpage that can convert writing in 50 languages. At first glance it looks like a basic text-to-text translator that resembles Google Translate and other simple language translation tools on the web. But scrolling down the page reveals more about OpenAI’s ambitions for Translate.

You’ll come across a line that mentions adding voice or an image (for instance, a photo of a sign) to get a translation, although the page doesn’t indicate when those capabilities will become available.

OpenAI’s breakout of Translate comes as its chief competitor, Google, is aggressively deploying AI to support features like live translations using headphones and new language learning tools. In 2024, Google added 110 languages to its translations.

Language translation is a hot field for artificial intelligence in general. At CES 2026 last week, for instance, CNET’s Macy Meyer tried out a phone-sized device and companion headphones that let her carry on a live conversation with a Polish speaker even though she doesn’t speak Polish herself.

The skills that ChatGPT Translate currently provides are things you can already do in the chatbot itself. In fact, once you translate text on the webpage, ChatGPT offers a set of sample prompts as one-click buttons for what you can do with that text, such as «translate this and make it sound more fluent» or «translate this as if you’re explaining it to a child.»

Selecting one of those prompts takes you to a ChatGPT conversation where options like image uploads are readily available.

OpenAI didn’t immediately respond to a request for comment.

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Don’t Miss the Samsung Galaxy Z Fold 7 While It’s $400 Off

A Galaxy Z Fold 7 is $50 cheaper on Amazon than at Samsung right now.

Who knew that foldable phones would be so popular again? If you’re looking for a foldable iPhone, you’re gonna need to wait until later this year. If you’re on the hunt for the best foldable phone you can get your hands on right now, you need to take a look at the Galaxy Z Fold 7. Normally $2,000, right now at both Amazon and Samsung, you can get a decent amount off that hefty price tag.

Amazon is dropping the silver version of Samsung’s foldable phone to $1,600. That’s an impressive $400 discount. If you prefer to shop at Samsung directly, you’ll end up paying $50 more as all colors of the Galaxy Z Fold 7 are down to $1,650. Neither of these are record-low prices, but Amazon is close enough at just $43 more.

Samsung’s unique foldable phones had an awkward adolescence, but after getting her hands on the new lineup, CNET reviewer Abrar Al-Heet confirms that the latest Z Fold 7 «just feels right.» For one, it’s incredibly sleek at just 8.9mm thick when closed or 4.2mm thick when open, which is so thin you may even forget that it’s foldable.

Despite weighing just 215 grams, this foldable features some serious hardware. It has a 6.5-inch cover screen and an 8-inch interior display with a fluid 120Hz refresh rate. It’s equipped with a cutting-edge Snapdragon 8 Elite processor and 12GB of RAM to support tons of helpful AI features and functions, and comes with Android 16 and Samsung One UI 8 right out of the box.

The camera system is also pretty impressive, boasting a 200-megapixel rear camera, 12-megapixel ultrawide shooting and a 10-megapixel front camera on both the cover and interior screens. Plus, it’s equipped with a 4,400-mAh battery for all-day use.
