Baby talk: a poor or smart decision?

‘She likes your high voice’ a friend of mine said to me once about his daughter. Yes, I am that person who talks in a sing-song voice when speaking to babies.  I’ve heard this voice many times when I am talking to my baby while standing at the supermarket checkout, with people around me smiling (smirking?) and probably wondering why I sound so cringe-worthy.

What is motherese?

What my friend is referring to is ‘motherese’ – the exaggerated way in which we talk to young children. When we use ‘motherese’, ‘baby-talk’ or ‘infant-directed speech’ as it is referred to in research, there are a number of changes in the way we speak:

  • Rate of speech: we speak more SLOWLY
  • Pitch of speech: we talk with a HIGHER (for many) or LOWER voice
  • Inflection patterns: we vary our inflection so that our voice goes UP and DOWN more
  • Simplicity of sounds: we often keep our words and sentence SIMPLE and SHORT
  • Physical distance: we get in CLOSE

What’s good about motherese?

The term baby talk first appeared in the Oxford English Dictionary in 1836.

Research tells us that babies find this kind of talking more interesting. Babies pay better attention and ‘tune-in’ more, especially amidst background noise.

When you exaggerate sounds by changing the length and pitch (e.g, where are your shooooes?”, it helps babies to differentiate between sounds. It becomes easier for them to know when one word finishes and the next one starts. Studies have shown that one year olds exposed to ‘infant-directed speech’ babbled more in response and in general. By two, these children had a larger vocabulary.

A study by Song et al, (2010) showed that slow speaking rate and vowel hyperarticulation (exaggerating vowels) significantly improved the 19 month olds’ ability to recognise words.

Can motherese be bad?

Using motherese doesn’t mean we should be speaking telegrammatically.

This is when we only use main content words and no grammar or grammatical errors (e.g., ‘he small’ instead of ‘he is small’, or ‘she eat’ instead of ‘She is eating’). Some people think this kind of talking helps a child’s language skills to develop, by only giving the most important words to focus on and is very simple.

However, telegrammatic speech is providing a poor language model for children to learn from. All children, at whatever age need to be exposed to good grammar in order to use it!

Some research (e.g. Fey, 2008) has found that found that using telegraphic speech may actually hinder a child’s language development, especially if the child has a language delay.

Additionally, the words, or parts of words we use when speaking grammatically provides information to your child about grammar. For example, when your child hears a word ending in ‘-ing’, they know that you are using an ‘action’ word and it is happening right now.

The best way to talk to your baby

  • Talk to your baby often
  • Use short sentences with correct grammar
  • Use real words
  • Repeat and emphasize words often
  • Use intonation and pitch variations

Make the smart choice to use baby talk – you may sound a little silly to other adults but watch as your bond grows and the interactions bring many moments of joy as your baby communicates with you!
