Baby Not Imitating Sounds

Editorially reviewed | Sources: AAP, CDC|Updated June 2026

The short answer

Sound imitation develops gradually - babies typically begin imitating vowel sounds around 4-6 months and consonant sounds by 8-10 months. This skill is a key building block for speech. If your baby is engaging with your voice, babbling on their own, and showing interest in communication, imitation is likely developing even if you haven't noticed it clearly yet.

Thousands of parents search for this exact thing. You are not alone.

By Age

What to expect by age

0-4 months

True sound imitation isn't expected yet. However, babies do engage in early "proto-conversations" - you talk, they coo, you respond, they coo again. This turn-taking is the earliest form of communicative imitation. Your baby may seem to match your pitch or rhythm even before imitating specific sounds.

4-7 months

Babies begin to imitate simple vowel sounds during this period. You might notice that if you say "oooh," your baby tries to make a similar sound back. This imitation may be inconsistent and subtle at first. Engaging in lots of face-to-face "conversation" where you imitate your baby's sounds encourages them to imitate yours.

7-10 months

Consonant sound imitation typically emerges now. Your baby may try to copy sounds like "ba," "da," or "ma" when you model them. They may also start imitating the rhythm and melody of speech even if they can't reproduce the exact sounds. This is sometimes called "jargoning" - babbling that sounds like speech with rising and falling intonation.

10-14 months

By 10-12 months, most babies are actively trying to imitate new sounds and words. If your baby is not imitating any sounds by 12 months and is also not babbling with consonant sounds, a hearing evaluation and speech-language assessment are appropriate. Sound imitation is closely linked to the development of first words.

What Should You Do?

When to take action

Probably normal when...
  • Your baby is under 6 months and engaging in turn-taking vocal play - cooing back when you talk - even without clear sound imitation.
  • Your baby imitates some sounds but not others, or imitates at some times but not on demand - imitation is emerging gradually.
  • Your baby is babbling enthusiastically on their own even if they don't seem to copy your specific sounds.
  • Your baby imitates actions and gestures (clapping, waving) even if sound imitation is lagging slightly behind.
Mention at your next visit when...
  • Your baby is over 9 months and makes no attempt to imitate any sounds, even simple vowel sounds.
  • Your baby doesn't seem interested in back-and-forth vocal play - they don't respond when you talk or babble to them.
  • Your baby is not babbling with consonant sounds by 9-10 months, which often coincides with limited sound imitation.
  • Your baby is 12 months or older and not imitating sounds or attempting words.
Act now when...
  • Your baby doesn't respond to sounds or voices at any age - this may indicate a hearing issue requiring urgent evaluation.
  • Your baby was imitating sounds and has stopped, especially if other social behaviors (eye contact, smiling) have also decreased.

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

Accent vs Speech Disorder in Bilingual Toddlers

When toddlers grow up hearing more than one language, they naturally blend sounds, patterns, and accents from both languages. This is normal and healthy, not a speech disorder. A bilingual child may pronounce some sounds differently than monolingual peers because they are learning the sound systems of two languages simultaneously. True speech disorders affect both languages equally, while accent influence appears only in specific sounds borrowed from one language to another.

Ear Fluid Affecting Baby's Speech Development

Chronic or recurrent middle ear fluid (otitis media with effusion) can temporarily reduce hearing by 15 to 40 decibels, which is like hearing through water. During critical periods of language learning, this muffled hearing can impact speech and language development. If your baby has frequent ear infections or persistent fluid, discuss the potential speech impact with your pediatrician.

Will Ear Tubes Help My Child's Speech?

Ear tubes (tympanostomy tubes) can restore normal hearing by draining persistent fluid from the middle ear. Many children show speech and language improvement within weeks to months after tube placement, particularly if hearing loss from fluid was contributing to their speech delay. However, ear tubes alone may not resolve all speech delays, and some children benefit from speech therapy alongside tube placement.

Baby Failed Newborn Hearing Screen - What Now?

Failing a newborn hearing screen does not necessarily mean your baby has hearing loss. Many babies who fail the initial screen pass on follow-up testing. However, it is critical to complete follow-up testing by 3 months of age. If hearing loss is confirmed, early intervention by 6 months of age leads to significantly better language outcomes.

Baby Using Jargon but No Real Words

Jargon babbling, which sounds like your baby is having a conversation in a made-up language, typically appears between 10 and 14 months and is a positive sign that your baby is learning the rhythm and melody of speech. Real words usually emerge from jargon over the following months. If no real words appear by 16 to 18 months, a speech evaluation may be helpful.

My Baby Is Losing Words or Skills

If your child was consistently using words and has truly stopped, this is something to act on promptly. Regression - the genuine loss of skills a child previously had - is different from a normal plateau or a toddler being too busy to talk, and it always warrants a conversation with your pediatrician sooner rather than later.
