New AI-Enabled Software May Translate Thoughts Into Speech

Mesgarani and his team planned to test more complicated words and to run the same tests on brain signals emitted when a person speaks or imagines speaking.

US engineers developed an Artificial Intelligence (AI)-enabled
system that can translate brain signals into intelligible speech, a breakthrough that may help those who cannot speak to communicate with the outside world.

The study, led by Columbia University researchers, showed that by monitoring one’s brain activity, an AI-enabled technology can reconstruct words a person hears with unprecedented clarity, Xinhua news agency reported.

A team of neuroscientists from the varsity trained a voice synthesiser or vocoder to measure brain activity patterns of epilepsy patients already undergoing surgery while those patients listened to sentences spoken by different people.

Those patients listened to speakers reading digits between zero to nine while recording brain signals via the vocoder.

Then, they used a neural network, a type of artificial intelligence, to analyse the signals, and gave robotic-sounding voices, according to the study published in the journal Scientific Reports.

“We found that people could understand and repeat the sounds about 75 per cent of the time, which is well above and beyond any previous attempts,” said Nima Mesgarani from the varsity.

Previous research showed that when people speak or even imagine speaking, distinct patterns of activity take place in their brain and those pattern of signals also emerge when we listen to someone speak or imagine listening.

Mesgarani and his team planned to test more complicated words and to run the same tests on brain signals emitted when a person speaks or imagines speaking.

Mesgarani called it a “game changer” that may give anyone who has lost their ability to speak a new chance to connect to the outside world. (IANS)

Adobe Built an AI To Spot Photoshopped Faces

This new research is part of a broader effort across Adobe to better detect image, video, audio and document manipulations

Adobe, along with researchers from the University of California, Berkeley, have trained Artificial Intelligence (AI) to detect facial manipulation in images edited using the Photoshop software.

At a time when deepfake visual content is getting commoner and more deceptive, the decision is also intended to make image forensics understandable for everyone.

“This new research is part of a broader effort across Adobe to better detect image, video, audio and document manipulations,” the company wrote in a blog-post on Friday.

As part of the programme, the team trained a convolutional neural network (CNN) to spot changes in images made with Photoshop’s “Face Away Liquify” feature, which was intentionally designed to change facial features like eyes and mouth.

On testing, it was found that while human eyes were able to judge the altered face 53 per cent of the time, the the trained neural network tool achieved results as high as 99 per cent.

The tool also identified specific areas and methods of facial warping.

Adobe’s execution in detecting facial manipulation came just days after doctored videos of Facebook CEO Mark Zuckerberg and US Speaker Nancy Pelosi made the rounds on social media as well as news channels.

“This is an important step in being able to detect certain types of image editing, and the undo capability works surprisingly well. Beyond technologies like this, the best defence will be a sophisticated public who know that content can be manipulated, often to delight them, but sometimes to mislead them as well,” said Gavin Miller, Head of Research, Adobe.

Adobe’s Photoshop software was originally released in 1990. (IANS)
