The benefits of baby talk: supporting early speech and language development

Early speech and language development supported through parent interaction

From birth, babies are learning how communication works. Long before children say their first words, they are already developing the foundations for speech, language, attention and social interaction.

One of the most effective and evidence-based ways to support this early development is through talking to your baby.

Often referred to as “baby talk” or “parentese”, the way adults naturally speak to babies plays a crucial role in early communication development. At Baby Speak, we regularly support families across London to build these foundations through responsive, everyday interaction.

This article explains what baby talk is, why it works, and how parents can use it to support early speech and language development.

What Is Baby Talk?

Baby talk does not mean using incorrect words or simplifying language excessively.

In clinical practice, we use the term parentese to describe a way of speaking that includes:

  • A warm, expressive tone

  • Slightly slower speech

  • Clear pronunciation

  • Short, grammatically correct sentences

  • Repetition

  • Talking about what your baby is attending to

For example:

“You’re holding the ball. A red ball. Roll the ball.”

Research shows that babies attend more closely to this type of speech and find it easier to process and learn from.

Why Talking to Your Baby Matters

The first three years of life are a critical period for brain development. During this time, babies are:

  • Learning how sounds work

  • Developing attention and listening skills

  • Building understanding before spoken language emerges

Language development does not happen through exposure alone. Babies learn best through responsive interaction, where adults notice and respond to their communication attempts.

The NHS highlights the importance of talking, playing and interacting with babies from birth to support speech and language development.

Evidence Behind Baby Talk

Research in early language development consistently shows that:

  • Babies prefer parent-directed speech to adult conversation

  • They engage for longer when speech is expressive and responsive

  • Vocabulary growth is strongly linked to caregiver responsiveness

  • Early interaction predicts later language and literacy outcomes

Tamis-LeMonda et al. (2001) and Rowe (2012) both demonstrate that the quality of interaction, not just the number of words, is key to language development.

How Baby Talk Supports Speech and Language Development

Building Understanding Before Speech

Children understand language before they can use words themselves. Talking about what your baby is looking at or doing helps them link words with meaning.

“Here’s your cup.”
“You’re kicking your legs.”

This supports receptive (understanding) language development.

Supporting Speech Sound Development

Clear, slightly exaggerated speech helps babies tune into speech sounds and begin learning how words are formed.

Encouraging First Words

Repetition of key words during everyday routines supports early vocabulary development and motivates babies to attempt communication.

The NHS recommends using everyday activities such as feeding, bathing and dressing as opportunities for language learning.

Developing Turn-Taking and Interaction

Responding to sounds, gestures and facial expressions teaches babies that communication is two-way. This is the foundation for later conversation skills.

Practical Ways to Use Baby Talk at Home

Parents do not need specialist resources. Effective support happens naturally within daily routines.

  • Talk during everyday activities

  • Follow your baby’s interests

  • Repeat key words

  • Pause to allow your baby time to respond

  • Use clear, real words rather than simplified language

These strategies support communication without increasing pressure or overstimulation.

Frequently Asked Questions

Is baby talk good for speech development?
Yes. “Baby talk” (often called parentese) supports early speech and language development because it helps babies pay attention to speech sounds, learn word patterns, and link words to meaning through interaction.

What is parentese and how is it different from baby talk?
Parentese is a research-backed style of talking to babies using a warm tone, clear pronunciation and slightly slower speech. It differs from unhelpful “baby talk” that uses incorrect words. Parentese uses real words and short, clear sentences.

How much should I talk to my baby each day?
There is no perfect number. The most helpful approach is frequent, responsive talk during everyday routines (feeding, dressing, bath time, play), with pauses so your baby can respond with looks, sounds or gestures.

Does reading to my baby help them talk?
Yes. Looking at books together supports listening, attention, early vocabulary and understanding. It works best when you comment on pictures, repeat key words, and follow your baby’s lead rather than reading every word on the page.

Can screen time replace talking to my baby?
No. Babies learn communication best through real human interaction. Video calls can be helpful when they involve back-and-forth interaction, but background TV and passive videos do not provide the same language learning benefits.

When should I be concerned about my baby’s speech and language development?
Consider seeking advice if your baby is not babbling by around 9-10 months, uses very few sounds/gestures, does not respond to their name, or is not using words by around 18 months. If you are unsure, an assessment can provide clarity and practical guidance.

Can a Speech and Language Therapist help even if my child is very young?
Yes. Early support often focuses on helping parents use evidence-based interaction strategies at home, as well as checking listening, attention, play and early communication skills.

Do you offer home visits in London?
Yes. Baby Speak offers private Speech and Language Therapy from our Harley Street clinic and home visits across North, Central, West and East London, as well as online consultations.

When to Seek Advice

All children develop at their own pace. However, families may wish to seek advice from a Speech and Language Therapist if a child:

  • Is not babbling by around 9–10 months

  • Uses very few sounds or gestures

  • Does not respond to their name

  • Is not using words by around 18 months

  • Appears frustrated when trying to communicate

NHS guidance on speech and language development can be found here.

A speech and language assessment can provide reassurance and practical guidance.
