What's coming next? Scientists identify how the brain predicts speech

Researchers have discovered how individual neurons coordinate to anticipate events in the brain's auditory cortex. This process is impaired in neurological and psychiatric disorders such as dyslexia and ADHD. By understanding these mechanisms, scientists hope to develop new models for studying predictive signals in the brain.

Whether our speech is fast or slow, we say about the same

A new study suggests that our speech is not just about speed, but also about conveying information efficiently. Researchers found that faster speech rates are associated with simpler word choices and syntax, while slower speech rates are linked to more complex words and structures. The study provides insights into how people craft thei...

How do children hear anger?

A team of researchers used functional magnetic resonance imaging (fMRI) and acoustic analysis to study how children's brains respond to emotional speech cues. They found that lower frequency characteristics in voice spectra may play a significant role in understanding brain activity and differentiating emotional processing.

Trump's political success was a triumph of style over substance: UBC research

A UBC study analyzing Trump's speech style and Twitter usage found grandiosity, informal language, and vocal pitch variation as statistical predictors of his success in the Republican primaries. The researchers suggest that these communication styles helped Trump win the nomination despite being shocking to many viewers.

Can a brain-computer interface convert your thoughts to text?

A recent study published in Frontiers presents a brain-to-text system that decodes speech from brain signals with high accuracy. The technology uses electrocorticography and language models to match patterns of neural signals to spoken words, offering potential benefits for individuals with speech disorders or locked-in patients.

It's not your ears, it's your brain

Researchers found that older adults' brains degrade speech processing in quiet environments, making it harder to comprehend speech amidst background noise. The study suggests that brain training techniques may help improve speech comprehension in older adults.

And the Oscar goes to ... climate change

A new study by SDSU researchers finds that DiCaprio's speech sparked record levels of public engagement with climate change, exceeding Earth Day and a major climate summit. The study analyzed news media trends, Twitter postings, and Google search trends to investigate global engagement with climate change since January 2011.

Voice control in orangutan gives clues to early human speech

A new study published in Scientific Reports suggests that orangutans have the potential capacity to control their voices, which could have led to the evolution of human speech. The research found that an adolescent orangutan named Rocky was able to copy the pitch and tone of sounds made by researchers, mimicking vowel-like calls.

Trolls often waive their anonymity online

A study by University of Zurich researchers found that individuals posting hate speech who used their full name were more common than anonymous trolls. Online anonymity is not a deterrent for hate speech, as it can actually increase credibility and popularity among trolls.

Brit accents vex US hearing-impaired elderly

A study from the University of Utah finds that older Americans with hearing loss have more trouble understanding British accents when there is background noise. The study also explores how transgender women can adopt a clearer speaking style to sound more feminine and how fast-talking affects speech intelligibility.

Music improves baby brain responses to music and speech

A recent study by the University of Washington's Institute for Learning & Brain Sciences found that 9-month-old babies who participated in music play sessions showed improved brain responses to music and new speech sounds. This suggests that early musical experiences can have a lasting impact on cognitive skills such as pattern percept...

Brain's 'amplifier' compensates for lost inner ear function

Researchers found that the adult brain's natural plasticity can compensate for a near-complete loss of auditory nerve fibers, restoring sensitivity to faint sounds but not complex sounds like speech. The brain's 'amplifier' at higher stages of processing acts as an amplifier, increasing sound detection abilities within normal limits.

Messages of individual blame for black Americans perpetuate racial inequality

A recent CDC report challenges the notion that Black fathers are more absent in their children's lives than White fathers. Researchers found that messages of individual blame for Black Americans perpetuate structural racial inequalities and reinforce the idea that Blacks are ultimately responsible for their own disadvantage.
