Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech. This is evident in the baby when born, showing many signs of early language comprehension.
Language development in humans is a process which starts early in life. Infants start without knowing a language, yet by 10 months, babies can distinguish speech sounds and engage in babbling . Some research has shown that the earliest learning begins in utero when the fetus starts to recognize the sounds and speech patterns of its mother's ...
Also, most low-frequency sounds (less than 300 Hz) can reach the fetal inner ear in the womb of mammals. [20] Those low-frequency sounds include pitch, rhythm, and phonetic information related to language. [21] Studies have indicated that fetuses react to and recognize differences between sounds. [22]
This task shows that children aged 15 to 20 months can assign meaning to a new word after only a single exposure. Fast mapping is a necessary ability for children to acquire the number of words they have to learn during the first few years of life: Children acquire an average of nine words per day between 18 months and 6 years of age.

The presence of such chemicals as adenosine, pregnanolone, and prostaglandin-D 2 in both human and animal fetuses, indicate that the fetus is both sedated and anesthetized when in the womb. These chemicals are oxidized with the newborn's first few breaths and washed out of the tissues, increasing consciousness. [ 13 ]
The acquisition process begins at birth, the brain begins to specialize in the sounds heard around them and begin to produce vowel-like sounds. This is the cooing stage. The babbling stage, six to 11 months, is when consonants like /m/ and /b/ are combined with vowels, m a-ma-ma ba-ba-ba .
New research suggests fluoride exposure during pregnancy could be linked to neurobehavioral issues in kids. But even the study’s authors — who were prompted to examine the issue based on ...
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
