Brain Circuit Balances Speech and Breath

Researchers identified a brain circuit that harmonizes vocalization with breathing, ensuring that speech occurs predominantly during exhalation. This circuit, which regulates the larynx's narrowing and the act of exhaling, is under the influence of a brainstem area responsible for the breathing rhythm.

Speech Speed May Indicate Aging Brain Health

A new study found that the speed of speech, rather than the difficulty in finding words, is a more accurate indicator of brain health in older adults. The research, involving 125 healthy volunteers aged 18 to 90, utilized AI software to analyze language performance, focusing on speech rate and word-finding pauses.

Brain Mastery Over Echoes Enhances Speech Clarity

Researchers have uncovered the human brain's remarkable ability to segregate direct speech from echoes, a challenge that has long perplexed audio engineers. It was discovered through magnetoencephalography (MEG) that despite the distortion caused by echoes, which typically lag by at least 100 milliseconds, the brain processes and understands speech with over 95% accuracy by separating the sound into distinct streams.
