At 4 months, infants still prefer infant-directed speech to adult-directed speech. Whereas 1-month-olds only exhibit this preference if the full speech signal is played to them, 4-month-old infants prefer infant-directed speech even when just the pitch contours are played. [6] This shows that between 1 and 4 months of age, infants improve in ...
Babbling begins shortly after birth and progresses through several stages as the infant's repertoire of sounds expands and vocalizations become more speech-like. [1] Infants typically begin to produce recognizable words when they are around 12 months of age, though babbling may continue for some time afterward. [2]
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 voice and differentiate them from other sounds after birth.

The production of spoken language involves three major levels of processing: conceptualization, formulation, and articulation. [1] [8] [9]The first is the processes of conceptualization or conceptual preparation, in which the intention to create speech links a desired concept to the particular spoken words to be expressed.
Hazan and Barrett (2000) [6] suggest that this development can cotton into late childhood; 6- to 12-year-old children showed increasing mastery of discriminating synthesized differences in place, manner, and voicing of speech sounds without yet achieving adult-like accuracy in their own production.
By the age of eighteen months, children typically attain a vocabulary of 50 words in production, and between two and three times greater in comprehension. [ 5 ] [ 7 ] A switch from an early stage of slow vocabulary growth to a later stage of faster growth is referred to as the vocabulary spurt . [ 13 ]
The study, presented at the 2017 Pediatric Academic Societies Meeting, revealed some frightening insight for parents and researchers worldwide.
