Long Before Their First Words, Babies' Brains Rehearse Speech Mechanics

Molly McElroy, University of Washington Infants can tell the difference between sounds of all languages until about 8 months of age when their brains start to focus only on the sounds they hear around them. It's been unclear how this transition occurs, but social interactions and caregivers' use of exaggerated "parentese" style of speech seem to help. University of Washington research in 7- and 11-month-old infants shows that speech sounds stimulate areas of the brain that coordinate...

University of Utah engineers show brain depends on vision to hear University of Utah bioengineers discovered our understanding of language may depend more heavily on vision than previously thought: under the right conditions, what you see can override what you hear. These findings suggest artificial hearing devices and speech-recognition software could benefit from a camera, not just a microphone. "For the first time, we were able to link the auditory signal in the brain to what a...

Dyslexia Roots Studied

Connie K. Ho for redOrbit.com — Your Universe Online Five percent. That´s the number of people who suffer from dyslexia worldwide, according to researchers at the College of Science at Northeastern University. Even with the number of people who suffer from the disorder, there still isn´t a clear reason as to what causes the disorder. With this in mind, a collaborative study was completed by researchers from Harvard Medical School, Western Galilee College, McGill...

Infant Speech Recognition More Advanced
2012-07-18 07:41:43

Connie K. Ho for redOrbit.com — Your Universe Online Sights and sounds are sensory details that are absorbed by a child early on. How much of that becomes recognizable to the infant is still being debated. According to researchers from New York University (NYU), an infant´s ability to recognize speech is more advanced that previously understood. While it´s known that adults have a fine-tuned perception of speech and an understanding of ambiguous sounds, less is known...

Grammatical Structures Key in Tuning Us to Speech In a study published in the open-access journal Frontiers in Language Sciences, researchers led by Prof. Iris Berent of Northeastern University show that our ability to identify sounds as speech critically depends on linguistic structures as opposed to acoustic properties.    In a world where the acoustic environment is rich with a buzzing, booming mixture of noises, bellows and musical tunes, humans identify speech...

When we speak, our enunciation and pronunciation of words and syllables fluctuates and varies from person to person. Given this, how do infants decode all of the spoken sounds they hear to learn words and meanings? To replicate the challenges of learning language as an infant, Carnegie Mellon University's Lori Holt and Sung-Joo Lim and Stockholm University's Francisco Lacerda used video game training with a mock "alien" language. They discovered that listeners quickly recognize word-like...

Your largest organ, the skin, plays a part in what you hear, Canadian researchers announced. Research found that silent puffs of air sent with specific sounds affected what people thought they were hearing. The results indicate that audio and visual hints were not the only ways people hear. In this unique study, researchers at the University of British Columbia in Vancouver wanted to determine if tactile feelings contribute to how sounds are heard. They used puffs of air accompanied by...

Music appreciation could help children with language-based learning disabilities The Journal of Neuroscience reports this week that musicians are better than non-musicians at recognizing speech in noisy environments.  The finding from a study conducted by neurobiologists at Northwestern University in Chicago is the first biological evidence that musicians' have a perceptual advantage for "speech-in-noise." When tested against non-musicians, musicians demonstrated faster neural timing,...

New research reveals that children with developmental dyslexia have a deficit in a brain mechanism involved in the perception of speech in a noisy environment. The study, published by Cell Press in the November 12 issue of the journal Neuron, provides the first direct evidence that the human auditory brainstem exhibits remarkable moment-to-moment plasticity and undergoes a fine tuning that is strongly associated with noise exclusion. Most people have little trouble carrying on a conversation...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
