Ear Infections and Speech Delay: What the Research Shows
Ear infections are very common — five out of six children have at least one by age 3 — and trapped fluid can affect hearing. But a meta-analysis found no to very small links between early ear fluid and later speech and language in otherwise healthy children. Persistent fluid or hearing loss deserves a hearing check.
Ear infections are very common
NIDCD states that five out of six children will have at least one ear infection by their third birthday. Children get them more often than adults partly because their eustachian tubes — which drain the middle ear — are smaller and more level, so fluid drains less easily, especially during a cold.1
| Type | What happens |
|---|---|
| Acute otitis media | The middle ear is infected and swollen, with fluid trapped behind the eardrum; causes ear pain, and sometimes a fever |
| Otitis media with effusion (“glue ear”) | Fluid stays behind the eardrum after the infection; there may be no symptoms |
| Chronic otitis media with effusion | Fluid remains for a long time or keeps returning, even without infection; can affect hearing |
Types of middle ear infection (NIDCD).1
What research says about speech
Whether early ear fluid causes later speech and language problems has long been debated. A meta-analysis of prospective studies in Pediatrics found no significant links between early otitis media with effusion and later receptive or expressive language in correlational studies, and none with vocabulary, syntax, or speech; group studies showed small negative associations with receptive and expressive language. The authors concluded there were no to very small negative associations — possibly overestimated — with uncertain clinical relevance for otherwise healthy children.2
The nuance
The research is about otherwise healthy children with temporary fluid. A child whose hearing stays reduced — from persistent fluid or another cause — is in a different situation and needs a hearing assessment.
Persistence is the key word. ASHA’s clinical guidance notes that persistent otitis media with effusion, often associated with hearing loss, has been associated with impaired speech development.4
Hearing does matter: ASHA lists hearing loss from ear infections or other causes among the factors that can contribute to speech sound disorders, and in a UK population cohort, hearing impairment at 7 and tympanostomy tube insertion were among the predictors of a persistent speech sound disorder at 8.5,3
Signs to watch for
- Trouble hearing or responding to quiet sounds.
- Tugging or pulling at the ears, fussiness, or trouble sleeping.
- Fluid draining from the ear, or fever.
- Speech that is not progressing, or quieter sounds (s, f, sh) consistently missing.
NIDCD lists these among the signs of an ear infection in a child too young to say their ear hurts. ASHA notes children with hearing loss may leave out quieter sounds like s, sh, f, t, or k.1,6

What to do
Mention any history of ear infections to your child’s SLP — ASHA lists it in the case history for speech sound assessment. If your child has had repeated infections or fluid and you have any doubt about their hearing, ask your pediatrician for a hearing test before or alongside a speech evaluation.4,7
Frequently asked questions
Can ear infections cause speech delay?＋
For most children, the evidence suggests little lasting effect. A meta-analysis of prospective studies found no to very small negative associations between early otitis media with effusion (ear fluid) and its hearing loss and children’s later speech and language, and judged the clinical relevance for otherwise healthy children uncertain. Children with ongoing hearing loss are a different matter and need a hearing assessment.
How common are ear infections?＋
Very common. NIDCD states that five out of six children will have at least one ear infection by their third birthday, partly because children’s eustachian tubes are smaller and more level, making it harder for fluid to drain.
What is glue ear?＋
Glue ear is the everyday name for otitis media with effusion (OME): fluid stays trapped behind the eardrum after an infection, often without pain. NIDCD notes a child with OME may have no symptoms, and that chronic OME can affect hearing.
Do ear infections show up on a speech evaluation?＋
Yes — ASHA lists the history of middle ear infections in the case history SLPs gather for a speech sound assessment. In one UK cohort, tympanostomy tube insertion and hearing impairment were among the predictors of a persistent speech sound disorder at 8.
