Infant directed speech (IDS) is a speech register characterized by simpler sentences, a slower rate, and more variable prosody. Recent work has implicated it in more subtle aspects of language development.
What are the prosodic characteristics of infant-directed speech?
Previous research has suggested that the prosodic characteristics of infant-directed speech are slowed speech rate, raised mean pitch, and expanded pitch range relative to adult-directed speech.
Does infant-directed speech improve infants' ability to discriminate vowels?
"Baby talk" or speech directed to prelinguistic infants is high in pitch and has exaggerated pitch contours (up/down patterns of pitch change) across languages and cultures. Using an acoustic model, we predicted that the large pitch contours of infant-directed speech should improve infants' ability to discriminate vowels.
What is child-directed speech and why is it important?
On any given day, an infant might overhear a parent talking to another caregiver, a parent talking to a sibling, phone conversations, a podcast, and more. But, child-directed speech is different because it is spoken intentionally to the baby. However, there’s more to child-directed speech.

Is infant-directed speech good or bad for language development?
Is Baby Talk Bad? A new study shows that true baby talk, made up of proper adult speech at a different cadence, is better for a baby's development than the regular baby babble we're used to. Researchers say it's better to talk to babies using proper grammar and real words at a higher pitch and a slower speed.

How often do children with autism go undiagnosed?
with autism spectrum disorder every year, while others go undiagnosed for an extended time, or even for their whole life. A child exhibiting delays in language benchmarks or showing little interest in the surroundings should be examined for possible ASD. Language is often impaired and although the level of impairment can range from severe too unnoticeable in each child, a child is likely to have a delay in another area, like coordination of motor skills, if not in language. Autism spectrum disorder
Is childhood a distinct phase of life?
level it is appropriate to teach them. Childhood has become such a distinct phase of the human life span that it is hard to imagine that it was not always thought of in that way. However, in medieval times, laws generally did not distinguish between child and adult offences and children were often treated like miniature adults. Today we view children quite differently than was the case in medieval times. We conceive of childhood as a highly eventful and unique time of life that lays an important foundation
What are the prosodic characteristics of infant-directed speech?
Previous research has suggested that the prosodic characteristics of infant-directed speech are slowed speech rate, raised mean pitch, and expanded pitch range relative to adult-directed speech. Sixteen mothers (5 Sri Lankan Tamil, 5 Tagalog, 6 Korean) were recorded in their homes during natural interactions with their young infants, and adults, over the course of 12 months beginning when the infant was 4 months old. Regression models indicated that the difference between infant- and adult-directed speech rates decreased across the first year of infants' development. Models of pitch revealed predicted differences between infant- and adult-directed speech but did not provide evidence for cross-linguistic or longitudinal effects within the time period investigated for the three languages. The universality of slowed speech rate, raised pitch, and expanded pitch range is discussed in light of individuals' highly variable implementation of these prosodic features in infant-directed speech.

What is child directed speech?
Child-directed speech is a dialect adults use when speaking to very young children. Child-directed speech can help build a young child’s vocabulary, create a social feedback loop, and improve language acquisition. Informally, it’s known as motherese, parentese, or baby talk. “Who wants a noodle?
Why is vocabulary important in school?
This relates to other research that shows that the more words a child knows, the more academic success they’ll achieve ( source ). Vocabulary knowledge is closely linked to reading comprehension abilities. And this plays an integral role throughout all subjects at school.
How do scientists study child directed speech?
In many of the studies, researchers use special “onesies” equipped with microphones to record what real babies or toddlers hear on a daily basis. Then, they painstakingly listen to the recordings and map out how much child-directed speech the children hear, as well as the content and characteristics of the language. Most studies also evaluate the child’s responses and their cognitive abilities over time.
