Cleft Palate and Speech: What Therapy Can and Cannot Do
Written by the Inclusive Developmental and Therapy Center therapy team — our Speech & Language Therapist, psychology and ABA staff. Clinical reviewer for this site: Dr Muhammad Suffyan, MB BS (GMC 8023727) · Updated August 2026; this page has changed since our last clinical review.
A cleft is a gap in the lip, the palate (the roof of the mouth), or both, that a child is born with. Families here often say harelip, or taalu khula hona. Repair is surgery. Timing and which hospital are a surgeon’s job. We do not operate, we do not fit plates, and we will not second-guess a cleft team from a WhatsApp photo.
What we do see, after repair or while families wait, is the speech and the hearing. Air that should stay in the mouth leaks into the nose. Sounds that need a closed palate come out weak or nasal. Glue ear is extremely common — NICE puts glue ear at 60–85% in children with a cleft palate. That is why this page sits beside glue ear, nasal speech and hearing and speech.
Why talking sounds different
The palate is a valve. For most speech sounds it lifts and closes off the nose so air comes out of the mouth. If there is still a gap, or the muscle cannot close fully after repair (doctors may say velopharyngeal insufficiency), air leaks. You hear:
- speech that sounds as if it is coming through the nose (hypernasal)
- weak pressure on p, b, t, d, k, g, s — they sound muffled or turn into a snort
- a grimace or extra effort in the face as the child tries to stop the leak
- words that are hard for strangers, even when the child has plenty of language
Language — vocabulary, sentences, understanding — can be typical. The problem is the plumbing of sound, plus whatever glue ear has stolen from listening. Do not assume the child is “slow” because they are hard to understand.
Ears first, almost always
The same anatomy that leaves a cleft often leaves poor middle-ear ventilation. Glue ear is the rule, not a side issue. Hearing that comes and goes means the child is copying muffled speech. Speech targets without a hearing test are guesswork.
Children with a cleft are not on the ordinary “wait three months” glue-ear clock. They need a specialist look earlier. We will say that in the room. We still cannot do the test ourselves.
What speech therapy is for — after the surgeon has done their part
Therapy cannot stitch a palate. After the structure is as good as it will be, we work on:
- hearing-aware listening and the sounds they can actually hear
- articulation they can reach with the palate they have — see unclear speech
- a way to ask and to be understood if speech is still limited — pictures, signs, a device. AAC is not a failure of surgery
- feeding and drinking only as everyday practice we can coach. Unsafe swallows belong with a hospital team. We do not assess swallowing
Some children also need a further surgical or specialist opinion if air still leaks after good therapy and a repaired palate. That decision is not ours. We will describe what we hear. We will not sell you more hours instead of a review they need.
What we will not do
We will not date an operation. We will not tell you which surgeon to use. We will not promise that speech will be “normal.” We will not put a child through oral-motor drills that ignore a leak they cannot control.
Inclusive Developmental and Therapy Center in Model Town, Multan works on communication alongside your cleft or ENT team. A consultation is Rs 1,500 and lasts up to 50 minutes. Bring the operation notes and any hearing report if you have them. If you have neither, come anyway — and expect us to send you for ears.
Frequently asked questions
Will speech therapy close a cleft?
No. A cleft is a structural gap. Repair is surgery. Therapy helps the child use the palate and the hearing they have, after or alongside surgical care. Anyone who promises that exercises will close a cleft is not telling the truth.
My child’s lip was repaired. Why is speech still nasal?
The lip and the palate do different jobs. A repaired lip does not automatically mean the valve at the back of the mouth is closing. Persistent nasal speech needs a hearing check and a specialist look at the palate, not only more drills. See nasal speech.
Why do you keep talking about glue ear?
Because it is very common with a cleft palate — NICE cites 60–85% in this group. Muffled hearing means muffled speech models. Get the ears checked early. Do not wait it out the way you might with an otherwise healthy toddler.
Should we wait for the next surgery before starting therapy?
You can start an assessment and parent coaching now: how you talk, how they ask, whether they can hear. We will not drill sounds the palate cannot make yet. Waiting years for a “final” operation with no communication support is how language falls behind as well as speech.
Do you work with babies with a cleft?
We can look at early communication and feeding-as-interaction. Medical feeding, plates and surgery stay with the hospital. If swallow safety is in doubt, that is a doctor, not us.
Will they ever be clear to strangers?
Many children are, after repair, hearing care and therapy. Some keep a nasal quality or a few weak sounds. We will describe what we hear and what is realistic. We will not guarantee an accent or a timeline.
