Dyslalia, also known as an articulation disorder, is a speech condition that causes difficulty pronouncing certain sounds or phonemes. It usually appears in childhood and affects the fluency of speech, since certain phonemes may be pronounced incorrectly, left out, or distorted, creating communication problems.
The term “dyslalia” comes from the Greek: “dys” meaning difficulty and “lalia” referring to speech. Dyslalia affects the ability to pronounce certain sounds that require specific coordination of the muscles and organs involved in speech, such as the tongue, lips and palate.
Types of dyslalia
There are several types of dyslalia depending on their cause or the type of difficulty articulating sounds:
- Functional dyslalia: Common in children, with no physical cause. Usually due to delayed development or coordination issues in the speech organs.
- Organic dyslalia: Linked to physical problems, such as a cleft palate or dental issues, that make correct articulation difficult.
- Developmental dyslalia: Appears in young children while they’re learning to speak and usually resolves naturally.
- Audiogenic dyslalia: Caused by hearing problems that affect the perception and reproduction of sounds.
Knowing which type of dyslalia is involved is essential for applying the right treatment, since each case responds differently to intervention.
Causes of dyslalia
The causes of dyslalia can vary, although some factors are common:
- Delayed speech development: Common in children and usually improves with time and practice.
- Functional causes: Occur when the speech apparatus doesn’t function properly.
- Hereditary factors: Genetic predisposition can play a role in some speech difficulties.
- Structural or organic problems: Issues with the mouth, teeth, tongue or palate can be a physical barrier to correct pronunciation.
- Environmental factors: A lack of verbal stimulation at home can contribute to speech difficulties.
- Hearing problems: Hearing plays a crucial role in correctly articulating sounds, so any hearing difficulty can lead to pronunciation errors.
Common symptoms of dyslalia
Symptoms of dyslalia can include:
- Substituting sounds, for example, saying “wabbit” instead of “rabbit”.
- Difficulty pronouncing specific words or sound patterns.
- Leaving out certain sounds in words.
- Distorting phonemes that are hard to pronounce.
- Adding extra sounds into words.
- Noticeable problems with how sounds are produced, such as difficulty positioning the tongue, lips or palate.
- Feelings of frustration when trying to communicate, or avoiding situations that involve speaking.
Each child may show a combination of these symptoms, and severity can vary from case to case.
Diagnosing dyslalia in children and adults
Dyslalia is diagnosed by a speech and language therapist, who assesses pronunciation errors using tools such as:
- Clinical history: information is gathered on any family history, to understand how the person has developed, or how a child is developing so far.
- Phonetic assessment: each phoneme is analysed to detect articulation problems.
- Hearing tests: since hearing problems can contribute to dyslalia, hearing tests are carried out to rule this out as a cause.
- Observation of oral motor skills: the movements of the tongue, lips and jaw are examined to detect coordination or muscle development issues.
Treatments for dyslalia
Treatment for dyslalia is usually effective and focuses on improving pronunciation through various techniques. Some options include:
- Speech and language therapy: this is the main treatment for dyslalia. The therapist works with the patient on exercises specific to each affected sound, helping correct articulation.
- Exercises at home: parents can support treatment by practising exercises at home with the child, always under the therapist’s guidance.
- Incorporating play into therapy: games are used to keep children motivated.
- Hearing devices: in cases of audiogenic dyslalia, using hearing aids or other devices can improve sound perception and, therefore, pronunciation.
- Technology-based tools: apps or programmes designed to treat this type of speech disorder can be used.
- Surgery: only considered in cases of organic dyslalia where structural problems make speech difficult, as part of the treatment plan.
Starting early intervention is key to more effective treatment, as it helps prevent pronunciation errors from becoming ingrained.
Tips for parents and educators
Support at home and at school is vital. These practical tips can help:
- Encourage speech: talking to the child clearly and often builds their interest in and practice of communication.
- Practise specific sounds: certain games can help children practise the sounds they find difficult.
- Use technology: this makes it more fun for the child while also improving pronunciation and speech.
- Gentle corrections: instead of correcting the child directly, parents can repeat the word correctly and naturally, so as not to discourage them.
- A positive, supportive environment: build confidence and support to avoid correcting the child in a negative way that could affect them.
When to seek help from a speech and language therapist
If a child over five years old still shows clear articulation difficulties, it’s a good idea to see a speech and language therapist. What’s more, if the dyslalia interferes with their ability to communicate or affects them emotionally, professional intervention is essential.
How can it be prevented?
Some preventive steps include:
- Prenatal care: taking special care before birth can reduce a range of risks and complications that could later affect speech development.
- Monitoring development: tracking the child to see how this important area — language — is developing, and identifying any existing or potential problems.
- An enriching environment: supporting language development by providing an environment with plenty of linguistic stimulation, social interaction, and anything else that fosters speech and language development.
- Early stimulation: encouraging speech from a very young age — talking to babies from their first months to support language development, as well as offering interactive toys.
- Hearing assessment: carrying out hearing tests from an early age and on a regular basis to detect any hearing problems, especially in children who suffer from frequent ear infections.
- Early intervention: as soon as a problem or sign related to speech sound disorders is detected, a specialist should step in to address it.
- A correct speech model: since children learn by imitation, adults should model accurate, correct pronunciation so speech develops optimally.
Prognosis and progression of dyslalia
The outlook is favourable in most cases, especially with early intervention. With the right support, most children overcome their difficulties and integrate fully into their social environment. The time needed to see improvement depends on the type of dyslalia, the child’s age, and how consistently the treatment is followed.
Dyslalia is a common condition that can affect children’s and adults’ ability to communicate. With the support of speech and language therapists and the commitment of family and educators, significant, lasting improvement is possible. Helping a child with dyslalia doesn’t just make speaking easier for them — it also strengthens their self-esteem and social skills.
If you notice speech difficulties in your child, it’s important to rule out possible hearing problems, since poor hearing can affect how sounds are articulated. A hearing assessment is a key first step to make sure hearing isn’t the underlying cause.

Frequently asked questions
Dyslalia is a speech disorder that causes difficulty correctly pronouncing certain sounds or letters. It usually appears in childhood and can be linked to problems in language development, hearing issues, difficulties with the speech organs, or poor pronunciation habits.
The main symptom is difficulty pronouncing certain sounds, substituting, omitting or distorting letters or syllables when speaking. This can affect communication and speech comprehension, especially in young children.
There are several types of dyslalia depending on their cause. These include developmental, functional, audiogenic and organic dyslalia. Each has different characteristics and requires proper professional assessment.
Yes. When a child doesn’t hear certain sounds correctly, they can struggle to learn to pronounce them properly. That’s why it’s important to get a hearing check-up if there are speech problems or language delays.
During the early years of language development, it’s common for some sounds not to be pronounced perfectly. However, if the difficulties continue beyond certain ages or affect communication, it’s worth consulting a professional.
Treatment depends on the cause and usually includes pronunciation exercises, language stimulation, and work with specialists such as speech and language therapists. When a hearing problem is involved, it’s also important to treat it properly.
It’s a good idea to seek advice when a child regularly struggles to communicate, mispronounces many sounds, isn’t easily understood for their age, or there’s suspicion of an underlying hearing loss.
