Scientists train AI to turn brain signals into speech

Neuroengineers have crafted a breakthrough device that uses machine-learning neural networks to read brain activity and translate it into speech.

An article, published Tuesday in the journal Scientific Reports, details how the team at Columbia University’s Zuckerman Mind Brain Behavior Institute used deep-learning algorithms and the same type of tech that powers devices like Apple’s Siri and the Amazon Echo to turn thought into “Accurate and intelligible reconstructed speech.” The research was reported earlier this month but the journal article goes into far greater depth.

If scientists can decode those signals and understand how they relate to forming or hearing words, then we get one step closer to translating them into speech.

That’s what the team has managed to do, creating a “Vocoder” that uses algorithms and neural networks to turn signals into speech.

Next, the patients listened to speakers counting from zero to nine, while their brain signals were fed back into the vocoder.

Looking forward, the team wants to test what kind of signals are emitted when a person just imagines speaking, as opposed to listening to speech.

Improving the algorithms with more data could eventually lead to a brain implant that bypasses speech altogether, turning a person’s thoughts into words.

Starting Your Day on the Internet Is Damaging Your Brain

I’ve said before the first 3 hours of your day can dictate how your life turns out.

You can either start you day with junk food for the brain or you can start the day with healthy food for the brain.

Anytime I start my day with junk food for the brain, the quality of the day goes down.

As Mark Manson so brilliantly said, cell phones are the new cigarettes, And a significant amount of what’s on the internet is nothing more than junk food for the brain.

The idea for this article was actually the result of giving my brain some health food to start the day.

So how exactly do you start the day with health food for your brain? To wean ourselves off of junk food for the brain, we have to actually replace it with something else.

You can accomplish extraordinary things in just one focused hour a day of uninterrupted creation time.

To predict the future, the brain uses two clocks: In music, sports and other activities, we calculate movement in two different parts of the brain — ScienceDaily

New University of California, Berkeley, research shows the neural networks supporting each of these timekeepers are split between two different parts of the brain, depending on the task at hand.

“Whether it’s sports, music, speech or even allocating attention, our study suggests that timing is not a unified process, but that there are two distinct ways in which we make temporal predictions and these depend on different parts of the brain,” said study lead author Assaf Breska, a postdoctoral researcher in neuroscience at UC Berkeley.

“Together, these brain systems allow us to not just exist in the moment, but to also actively anticipate the future,” said study senior author Richard Ivry, a UC Berkeley neuroscientist.

Both are primal brain regions associated with movement and cognition.

Non-pharmaceutical fixes for neurological timing deficits could include brain-training computer games and smartphone apps, deep brain stimulation and environmental design modifications, he said.

Ultimately, the results confirm that the brain uses two different mechanisms for anticipatory timing, challenging theories that a single brain system handles all our timing needs, researchers said.

“Our results suggest at least two different ways in which the brain has evolved to anticipate the future,” said Breska.
