&lt;p&gt;An artificial intelligence can decode words and sentences from brain activity with surprising &amp;mdash; but still limited &amp;mdash; accuracy. Using only a few seconds of brain activity data, the AI guesses what a person has heard. It lists the correct answer in its top 10 possibilities up to 73 percent of the time, researchers found in a preliminary study.&lt;/p&gt;
&lt;p&gt;The AI&amp;rsquo;s &amp;ldquo;performance was above what many people thought was possible at this stage,&amp;rdquo; says Giovanni Di Liberto, a computer scientist at Trinity College Dublin who was not involved in the research.&lt;/p&gt;
&lt;p&gt;Developed at the parent company of Facebook, Meta, the AI could eventually be used to help thousands of people around the world &lt;a href=&quot;https://arxiv.org/abs/2208.12266&quot; rel=&quot;noopener&quot; target=&quot;_blank&quot;&gt;unable to communicate through speech, typing or gestures&lt;/a&gt;, researchers report August 25 at arXiv.org. That includes many patients in minimally conscious, locked-in or &amp;ldquo;vegetative states&amp;rdquo; &amp;mdash; what&amp;rsquo;s now generally known as &lt;a href=&quot;https://www.sciencenews.org/article/brain-scans-decode-elusive-signature-consciousness&quot;&gt;unresponsive wakefulness syndrome&lt;/a&gt; (&lt;em&gt;SN: 2/8/19&lt;/em&gt;).&lt;/p&gt;
&lt;p&gt;Most existing technologies to help such patients communicate require risky brain surgeries to implant electrodes. This new approach &amp;ldquo;could provide a viable path to help patients with communication deficits &amp;hellip; without the use of invasive methods,&amp;rdquo; says neuroscientist Jean-R&amp;eacute;mi King, a Meta AI researcher currently at the &amp;Eacute;cole Normale Sup&amp;eacute;rieure in Paris.&lt;/p&gt;
&lt;p&gt;King and his colleagues trained a computational tool to detect words and sentences on 56,000 hours of speech recordings from 53 languages. The tool, also known as a language model, learned how to recognize specific features of language both at a fine-grained level &amp;mdash; think letters or syllables &amp;mdash; and at a broader level, such as a word or sentence.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
