The human brain tracks speech more closely in time than other sounds

Summary: Research suggests a time-locked encoding mechanism may have evolved for speech processing in humans. The processing mechanism appears to be tuned to the native language as a result of extensive exposure to the language environment during early development.

Humans can effortlessly recognize and react to natural sounds and are especially tuned to speech. There have been several studies aimed to localize and understand the speech-specific parts of the brain, but as the same brain areas are mostly active for all sounds, it has remained unclear whether or not the brain has unique processes for speech processing, and how it performs these processes. One of the main challenges has been to describe how the brain matches highly variable acoustic signals to linguistic representations when there is no one-to-one correspondence between the two, e.g. how the brain identifies the same words spoken by very different speakers and dialects as the same.

Can a Newborn’s Brain Discriminate Speech Sounds?
Summary: It’s a question most new parents ponder, can a newborn baby discriminate between speech sounds? Researchers found newborn babies encode voice pitch comparable to adults exposed to a new language for three years. However, there are some differences when it comes to distinguishing between spectral and temporal fine structures of certain sounds.

People’s ability to perceive speech sounds has been deeply studied, specifically during someone’s first year of life. But what happens during the first hours after birth? Are babies born with innate abilities to perceive speech sounds, or do neural encoding processes need to age for some time?
Changing the Connection Between the Hemispheres Affects Speech Perception
Summary: Using HD-TACS brain stimulation, researchers influenced the integration of speech sounds by changing the balancing processes between the two brain hemispheres.

When we listen to speech sounds, the information that enters our left and right ear is not exactly the same. This may be because acoustic information reaches one ear before the other, or because the sound is perceived as louder by one of the ears. Information about speech sounds also reaches different parts of our brain, and the two hemispheres are specialised in processing different types of acoustic information. But how does the brain integrate auditory information from different areas?
