Brain-to-speech interfaces have been promising to help paralyzed individuals communicate for years. Unfortunately, many systems have had significant latency that has left them lacking somewhat in the practicality stakes.
A team of researchers across UC Berkeley and UC San Francisco has been working on the problem and made significant strides forward in capability. A new system developed by the team offers near-real-time speech—capturing brain signals and synthesizing intelligible audio faster than ever before.
New Capability
The aim of the work was to create more naturalistic speech using a brain implant and voice synthesizer. While this technology has been pursued previously, it faced serious issues around latency, with delays of around eight seconds to decode signals and produce an audible sentence. New techniques had to be developed to try and speed up the process to slash the delay between a user trying to “speak” and the hardware outputting the synthesized voice.
The implant developed by researchers is used to sample data from the speech sensorimotor cortex of the brain—the area that controls the mechanical hardware that makes speech: the face, vocal chords, and all the other associated body parts that help us vocalize. The implant captures signals via an electrode array surgically implanted into the brain itself. The data captured by the implant is then passed to an AI model which figures out how to turn that signal into the right audio output to create speech. “We are essentially intercepting signals where the thought is translated into articulation and in the middle of that motor control,” said Cheol Jun Cho, a Ph.D student at UC Berkeley. “So what we’re decoding is after a thought has happened, after we’ve decided what to say, after we’ve decided what words to use, and how to move our vocal-tract muscles.”
The AI model had to be trained to perform this role. This was achieved by having a subject, Ann, look at prompts and attempting to “speak ” the phrases. Ann has suffered from paralysis after a stroke which left her unable to speak. However, when she attempts to speak, relevant regions in her brain still lit up with activity, and sampling this enabled the AI to correlate certain brain activity to intended speech. Unfortunately, since Ann could no longer vocalize herself, there was no target audio for the AI to correlate the brain data with. Instead, researchers used a text-to-speech system to generate simulated target audio for the AI to match with the brain data during training. “We also used Ann’s pre-injury voice, so when we decode the output, it sounds more like her,” explains Cho. A recording of Ann speaking at her wedding provided source material to help personalize the speech synthesis to sound more like her original speaking voice.
To measure performance of the new system, the team compared the time it took the system to generate speech to the first indications of speech intent in Ann’s brain signals. “We can see relative to that intent signal, within one second, we are getting the first sound out,” said Gopala Anumanchipalli, one of the researchers involved in the study. “And the device can continuously decode speech, so Ann can keep speaking without interruption.” Crucially, too, this speedier method didn’t compromise accuracy—in this regard, it decoded just as well as previous slower systems.

The algorithms used to decode the signals were not dissimilar from those used by smart assistants like Siri and Alexa, Anumanchipalli explains. “Using a similar type of algorithm, we found that we could decode neural data and, for the first time, enable near-synchronous voice streaming,” he says. “The result is more naturalistic, fluent speech synthesis.”
It was also key to determine whether the AI model
was genuinely communicating what Ann was trying to say. To investigate this, Ann was qsked to try and vocalize words outside the original training data set—things like the NATO phonetic alphabet, for example. “We wanted to see if we could generalize to the unseen words and really decode Ann’s patterns of speaking,” said Anumanchipalli. “We found that our model does this well, which shows that it is indeed learning the building blocks of sound or voice.”
For now, this is still groundbreaking research—it’s at the cutting edge of machine learning and brain-computer interfaces. Indeed, it’s the former that seems to be making a huge difference to the latter, with neural networks seemingly the perfect solution for decoding the minute details of what’s happening with our brainwaves. Still, it shows us just what could be possible down the line as the distance between us and our computers continues to get ever smaller.

Rear-view mirrors are important safety tools, but [Mike Kelly] observed that cyclists (himself included) faced hurdles to using them effectively. His solution? A helmet-mounted dual-mirror system he’s calling the Mantis Mirror that looks eminently DIY-able to any motivated hacker who enjoys cycling. One mirror for upright body positions, the other for lower positions. Carefully placed mirrors eliminate blind spots, but a cyclist’s position changes depending on how they are riding and this means mirrors aren’t a simple solution. Mirrors that are aligned just right when one is upright become useless once a cyclist bends down. On top of that, road vibrations have a habit of knocking even the most tightly-cinched mirror out of alignment.
[Mike]’s solution was to attach two small mirrors on a short extension, anchored to a cyclist’s helmet. The bottom mirror provides a solid rear view from an upright position, and the top mirror lets one see backward when in low positions.
[Mike] was delighted with his results, and got enough interest from others that he’s considering a crowdfunding campaign to turn it into a product. In the meantime, we’d love to hear about it if you decide to tinker up your own version.
You can learn all about the Mantis Mirror in the video below, and if you want to see the device itself a bit clearer, you can see that in some local news coverage.

One might be tempted to think that re-creating a film robot from the 1950s would be easy given all the tools and technology available to the modern hobbyist, but as [Mike Ogrinz]’s quest to re-create Robby the Robot shows us, there is a lot moving around inside that domed head, and requires careful and clever work. The “dome gyros” are just one of the complex assemblies, improved over the original design with the addition of things like bearings. Just as one example, topping Robby’s head is a mechanical assembly known as the dome gyros. It looks simple, but as the video (embedded below) shows, re-creating it involves a load of moving parts and looks like a fantastic amount of work has gone into it. At least bearings are inexpensive and common nowadays, and not having to meet film deadlines also means one can afford to design things in a way that allows for easier disassembly and maintenance.
Robby the Robot first appeared in the 1956 film Forbidden Planet and went on to appear in other movies and television programs. Robby went up for auction in 2017 and luckily [Mike] was able to take tons of reference photos. Combined with other enthusiasts’ efforts, his replica is shaping up nicely.
We’ve seen [Mike]’s work before when he shared his radioactive Night Blossoms which will glow for decades to come. His work on Robby looks amazing, and we can’t wait to see how it progresses.

Posts made by a Fosstodon server moderator on Reddit has caused some drama, leading to both Fosstodon admins to call it quits, a number of servers (threatening to) defederate from the Fosstodon server, leading to an uncertain future for the Fosstodon server.
Fosstodon drama
A few days ago someone published a post on Mastodon, with screenshots and links to posts made on Reddit by one of the Fosstodon moderators. In the linked posts, the Reddit account in question, which seemingly belongs to the Fosstodon moderator, holds various right-wing beliefs, ranging from defending the deportation of Mahmoud Khalil to claiming Democrat supporters are in a cult. Backlash to the Fosstodon server was swift and strong, with various calls and plans from other servers to defederate from Fosstodon, members of the Fosstodon server looking for other servers to move their account to, and a general condemnation from the wider community. Both Fosstodon admins have postedarticles declaring they are stepping down, citing not only the current drama as a reason, but that they see the work of being server admins as frustrating with little pay-off. One Fosstodon community member is considering to take over the administration of the server, though as of writing, that process is still ongoing and the outcome unclear.
Some thoughts and takeaways about what this drama says about the social side of federation on the network, and how different communities interact:
When a server moderators holds opinions other people view as problematic, the social cost of these views is partially extended to server users as well. See for example the account for fediverse streaming platform Owncast, which has an account on the Fosstodon server. Owncast says that they are getting messages that say they need to move servers, otherwise people will see them as Nazis. This blog post about another Fosstodon user explains a similar thought process, where it is rational for them to move to a different server, because they will be associated with the politics of the server moderator in question otherwise.
This behaviour has an impact on how people on the fediverse should find an instance they want to join. It turns out that knowing the political affiliations of server moderators is important, and that this is something that people should know about before joining a server. People will be judged for being on a server that has a moderator with toxic political views. As such, it becomes important for people to know this information beforehand: both that they will get judged for the politics of server moderators, as well as knowing what those political views actually are.
This is another indication of why the process of selecting a server when someone joins the fediverse is actually a challenge: important information that should impact server choice is not made available to users, nor is it made clear that this information is important in the first place.
The second takeaway from the situation is that it shows a need for fediverse servers to have a federation policy. How federation currently works on the fediverse is that servers are connected with each other by default, and the assumption is that servers can disconnect from each other for any reason, but will mostly do so only if one of the servers is misbehaving in some way. Freedom of association is one of the valuable features of the fediv erse. Server operators should be free to defederate from any other server, for any reason. Being able to defederate from another server because you strongly disagree with the politics from one of the server moderators is a good thing. But if this is a consistent policy of the server, it would do well to make this policy public and explicit. Servers defederating from each other can have significant impact on users, who suddenly can lose connections with their friends. A policy of defederating from other servers based on the expressed beliefs of server moderators is something that is not immediately obvious to new people joining the fediverse. There are absolutely valid reasons to do so, but it seems to me that formalising such a policy would be a good step towards making the culture on the fediverse more sustainable.
The third takeaway is that running a fediverse server is challenging, especially over longer periods of time. Both Fosstodon admins have called in quits in response to the most recent drama. Their blog posts explaining their perspectives is that this has been a long time coming, and that the Fosstodon server has been uncompensated work that they do not love doing for years now. Regardless of one’s perspective on how the admins handled the latest situation, it is a further indication that being a fediverse server admin is a challenging job, one that should not be expected that someone can do forever. This means that servers like Fosstodon need governance systems that allow for better and earlier rotation of administrative power. Fediverse software should also be better at dealing with the realities of admin burnout. The users who are transferring from Fosstodon to another server will lose their posts; Mastodon does only transfer the social graph, and not posting history. While ideally the majority of servers would have extensive governance systems in place that can help deal with admin burnout, the reality is that most servers do not. More fediverse software should provide better support for users having to move to different servers, including with their posts.
