How do their brains change from stroke? https://medicalxpress.com/news/2025-12-speech-comprehension.html Mon, 29 Dec 2025 13:00:01 EST news685792604 How does the brain manage to catch the drift of a mumbled sentence or a flat, robotic voice? A new study led by researchers at Reichman University's Baruch Ivcher School of Psychology and the Dina Recanati School of Medicine has uncovered that the human brain dynamically reconfigures large-scale neural networks during speech processing, offering new insights into the neural mechanisms underlying language comprehension. https://medicalxpress.com/news/2025-12-brain-dynamically-reconfigures-networks-speech.html Tue, 16 Dec 2025 14:58:28 EST news685119481 A study from Charles University and the Czech Academy of Sciences revisits a long-standing idea in language science that speech sounds from one's native language elicit stronger brain responses than speech sounds from a foreign language. https://medicalxpress.com/news/2025-12-phoneme-effect-revisits-key-assumption.html Mon, 01 Dec 2025 13:11:07 EST news683817000 The way we speak in everyday conversation may hold important clues about brain health, according to new research from Baycrest, the University of Toronto and York University. The study found that subtle features of speech timing—such as pauses, fillers ("uh," "um") and word-finding difficulty—are strongly linked to executive function, the set of mental skills that support memory, planning and flexible thinking. https://medicalxpress.com/news/2025-11-everyday-speech-reveal-early-brain.html Tue, 11 Nov 2025 18:40:02 EST news682098561 A new study from King's College London has revealed that artificial intelligence (AI) automatic speech recognition (ASR) tools could dramatically improve how dental professionals record patient information—saving time and reducing administrative burden. https://medicalxpress.com/news/2025-11-ai-speech-tools-revolutionize-dental.html Thu, 06 Nov 2025 17:40:01 EST news681644317 Researchers in Shanghai have reported in a study, recently published in Science Advances, that they've successfully decoded Mandarin Chinese language in real time with the help of a brain-computer interface (BCI) framework, a first for BCIs working with tonal languages.

New clinical data now challenge this practice. A study using endoscopic swallowing diagnostics in patients with poststroke dysphagia has shown that whole tablets, when administered with a soft bolus such as applesauce, are often swallowed safely—without signs of penetration or aspiration. In contrast, crushed forms left significantly more residue in the pharynx, potentially impairing drug absorption and increasing the risk of complications. https://medicalxpress.com/news/2025-10-tablets-safer-patients-poststroke-swallowing.html Tue, 28 Oct 2025 15:02:04 EDT news680882522 Standard MRI scans of a person's tongue could assist in the early detection and ongoing monitoring of motor neuron disease. https://medicalxpress.com/news/2025-10-scanning-tongue-track-motor-neuron.html Thu, 23 Oct 2025 07:04:04 EDT news680421841 Delays in language and reading development are common, and learning disorders such as dyslexia can significantly affect a child's educational path and later opportunities. The earlier support is given, the easier it is for children to build strong language and reading skills. https://medicalxpress.com/news/2025-10-infant-brain-patterns-linked-future.html Tue, 21 Oct 2025 16:00:03 EDT news680281202 Around a third of autistic people—children and adults alike—are unable to share what they want using speech. https://medicalxpress.com/news/2025-10-autistic-people-dont.html Wed, 15 Oct 2025 11:20:03 EDT news679746001 More than a million people around the world rely on cochlear implants (CIs) to hear. CI effectiveness is generally evaluated through speech recognition tests, and despite how widespread they are, CI sound quality is typically not considered an indicator of users' quality of life. https://medicalxpress.com/news/2025-10-speech-recognition-cochlear-implants.html Tue, 14 Oct 2025 11:00:01 EDT news679563362 Cochlear implants give children with profound hearing loss a much better chance to learn spoken language. However, the sounds from a cochlear implant aren't as clear as natural hearing, making it harder for children to connect the way they move their mouths with the sounds they hear. https://medicalxpress.com/news/2025-10-exploring-children-loss.html Sun, 12 Oct 2025 12:20:01 EDT news679310300 An AI-powered hearing test is reliably able to check your hearing on a computer or smart phone without clinical supervision, according to a study by University of Manchester researchers. https://medicalxpress.com/news/2025-10-ai-powered-automated-scientists.html Thu, 02 Oct 2025 09:21:05 EDT news678615662 Schizophrenia is a chronic mental health disorder characterized by hallucinations, delusions, disorganized thinking and atypical movement or speech patterns.

Neuroscientists thought that your brain may turn up its processing speed as well. But it turns out that at least the auditory part of the brain keeps "listening" or clocking in at a fixed time. That is the key finding of new research appearing in Nature Neuroscience. https://medicalxpress.com/news/2025-09-millisecond-windows-key.html Thu, 18 Sep 2025 05:00:01 EDT news677343601 Words are windows into the brain. The words that we choose—and how we say them—speak volumes about our personalities and even our mental health, said WashU psychologist Josh Oltmanns. "Our thoughts, feelings and behaviors are reflected in language," he said. https://medicalxpress.com/news/2025-09-ai-tool-psychologists-revealing-personality.html Wed, 10 Sep 2025 12:32:04 EDT news676726321 Run.
