Microsoft’s new AI can simulate anyone’s voice with 3 seconds of audio

Posted by in category: robotics/AI

On Thursday, Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person’s voice when given a three-second audio sample. Once it learns a specific voice, VALL-E can synthesize audio of that person saying anything—and do it in a way that attempts to preserve the speaker’s emotional tone.

Microsoft calls VALL-E a “neural codec language model,” and it builds off of a technology called EnCodec, which Meta announced in October 2022. Unlike other text-to-speech methods that typically synthesize speech by manipulating waveforms, VALL-E generates discrete audio codec codes from text and acoustic prompts.

Controversy erupts over non-consensual AI mental health experiment

Posted by in categories: neuroscience, robotics/AI

On Friday, Koko co-founder Rob Morris announced on Twitter that his company ran an experiment to provide AI-written mental health counseling for 4,000 people without informing them first, The Verge reports. Critics have called the experiment deeply unethical because Koko did not obtain informed consent from people seeking counseling.

On Discord, users sign into the Koko Cares server and send direct messages to a Koko bot that asks several multiple-choice questions (e.g., “What’s the darkest thought you have about this?”). It then shares a person’s concerns—written as a few sentences of text—anonymously with someone else on the server who can reply anonymously with a short message of their own.

One Step Closer to Deeper Explorations Into Space — Improved Performance of Plasma Thrusters

Posted by in category: space travel

A researcher at Tohoku University has made significant improvements to a high-power electrodeless plasma.

Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of positive ions and free electrons. It was first described by chemist Irving Langmuir in the 1920s.

Breakthrough in Quantum Research Paves Way for New Generation of Light-Driven Electronics

Posted by in categories: biotech/medical, chemistry, computing, quantum physics

A breakthrough in quantum research – the first detection of excitons (electrically neutral quasiparticles) in a topological insulator has been achieved by an international team of scientists collaborating within the Würzburg-Dresden Cluster of Excellence ct.qmat. This discovery paves the way for a new generation of light-driven computer chips and quantum technologies. It was enabled thanks to smart material design in Würzburg, the birthplace of topological insulators. The findings have been published in the journal Nature Communications.

<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio. It covers the natural sciences, including physics, biology, chemistry, medicine, and earth sciences. It began publishing in 2010 and has editorial offices in London, Berlin, New York City, and Shanghai.

Expert Analysis Reveals Cryptographic Weaknesses in Threema Messaging App

Posted by in categories: biotech/medical, encryption, security

A comprehensive analysis of the cryptographic protocols used in the Swiss encrypted messaging application Threema has revealed a number of loopholes that could be exploited to break authentication protections and even recover users’ private keys.

The seven attacks span three different threat models, according to ETH Zurich researchers Kenneth G. Paterson, Matteo Scarlata, and Kien Tuong Truong, who reported the issues to Threema on October 3, 2022. The weaknesses have since been addressed as part of updates released by the company on November 29, 2022.

Threema is an encrypted messaging app that’s used by more than 11 million users as of October 2022. “Security and privacy are deeply ingrained in Threema’s DNA,” the company claims on its website.

Italian Users Warned of Malware Attack Targeting Sensitive Information

Posted by in category: cybercrime/malcode

A new malware campaign has been observed targeting Italy with phishing emails designed to deploy an information stealer on compromised Windows systems.

“The info-stealer malware steals sensitive information like system info, crypto wallet and browser histories, cookies, and credentials of crypto wallets from victim machines,” Uptycs security researcher Karthickkumar Kathiresan said in a report.

Details of the campaign were first disclosed by Milan-based IT services firm SI.net last month.

Metabolic regulation of species-specific developmental rates

Posted by in category: futurism

An in vitro system that recapitulates temporal characteristics of embryonic development demonstrates that the different rates of mouse and human embryonic development stem from differences in metabolic rates and—further downstream—the global rate of protein synthesis.
