Humans Slow Speech to Help Dogs Understand

A new study reveals that humans naturally slow their speech when talking to dogs, which helps dogs better understand commands. Researchers analyzed speech rates and brain responses in 30 dogs and 27 humans across five languages, finding that humans speak at around three syllables per second to their pets, compared to four syllables when talking to other humans.

Right-Sided DBS: Effective Parkinson’s Treatment Without Speech Loss

A new study has shown that unilateral deep brain stimulation (DBS) on the right side of the brain improves motor symptoms in Parkinson's patients without causing significant declines in verbal fluency. Researchers found that DBS on the left hemisphere led to more noticeable declines in word retrieval and generation.

Improving Voice Recognition for People with Speech Disabilities

A new study shows that automatic speech recognition (ASR) systems trained on speech from people with Parkinson’s disease are 30% more accurate in transcribing similar speech patterns. Researchers collected over 151 hours of recordings from participants with varying degrees of dysarthria, a speech disorder common in Parkinson’s patients, and used the data to train ASR systems.

How the Brain Distinguishes Music from Speech

A new study reveals how our brain distinguishes between music and speech using simple acoustic parameters. Researchers found that slower, steady sounds are perceived as music, while faster, irregular sounds are perceived as speech.

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.
