Each stage has an age range (in months), an MLU range, structure types, and examples. MLU stands for “Mean Length of Utterance” – this does not always refer to number of words, but to number of morphemes, or units or meaning, in an utterance. For example, “happy” contains only one unit of meaning, so it is one morpheme.

This content was developed as a collective resource of norms for speech-language development. SLPs are often asked questions regarding typical age of sound acquisition and development of language. These resources will assist in answering those questions and providing resources to parents and colleagues.

Mean Length of Utterance (MLU) www.sltinfo.com There is, therefore, a total of 17 morphemes. Now, in order to find the mean length of utterance we take the total number of morphemes (17) and divide it by the total number of utterances (4). Thus, the mean length of utterance is 17/4 = 4.25. What we need to do now is determine the age at which

The correlations were then calculated for 3 age levels within each group defined as 2;6 to 4;11;5;6 to 6;11 years; and 7;0 to 9;0 years. Only the unaffected 5;0-to-6;11-year-old group yielded a significant correlation, r (36) = −.358, p = .03, suggesting higher MLU levels for the children of less well educated mothers. Overall, in these ...

intervals from ages 2 to 9 (Rice M, Smolik F, et al. Mean length of utterance levels in 6-month intervals for children 3 to 9 years without language impairments. J Speech Lang Hear Res. 53 (2): 333-349). Of particular help is the fact that their new database is developed specifically for using MLU in clinical decision-making.

analyze it to determine the child’s MLU and will also refer to Brown’s Stages to identify where the child is in his or her language development. Age MLU Structure Examples 12-26 months 1.0 – 2.0 50-60 word vocabulary; basic phrases/sentences that show communicative intent more water no juice my toys Age MLU Structure Examples 27-30 months ...

1 – 2 Years. Syntax: The child uses one-word sentences; Average MLU = 1.0 – 2.0; The child uses sentence-like words; communicates relationships by using one word plus vocal and bodily cues. The sentence-like word can serve several functions: Between approximately 18-24 months of age, children begin to put two words together.

Mean Length of Utterance (MLU) is a key metric used in language development studies to assess the linguistic complexity of a child's speech. By calculating the average length of a child’s spoken sentences or phrases, researchers and clinicians can gain insights into language acquisition progress. ... For a 2-year-old, an MLU around 2.0 is ...

Mean length of utterance (or MLU) is a measure of linguistic productivity in children. It is traditionally calculated by collecting 100 utterances spoken by a child and dividing the number of morphemes by the number of utterances. A higher MLU is taken to indicate a higher level of language proficiency. The mean length of utterance (MLU) was ...

What’s an MLU? “MLU” is an acronym for Mean Length of Utterance. In this case, “Mean” refers to an average, and “Utterance” refers to a phrase or a sentence. Therefore, when we say “MLU,” we are talking about the average number of morphemes –– not words –– in a child’s phrase or sentence.

Lower MLU may indicate a speech/language delay. Higher MLU shows more advanced grammar skills. For example: A typically developing 3-year-old may have an MLU around 3.0, using short sentences like “I want juice.” An MLU of 2.0 at that age could mean the child needs support building vocabulary and grammar skills.

For example, a 22-month-old child may say, "More milk" when she means, "I would like more milk now." Stage II. By stage two, the child's mean length of utterances -- or MLU -- has grown to between two and 2.5. The MLU refers to the total number of morphemes -- or smallest unit of meaning -- divided by how many utterances the child makes.

Eisenberg et al.: Use of MLU for Identifying Language Impairment 325 Population We will refer to two sets of reference data for MLU. Miller and Chapman (1981, abbrevi-ated as MC) reported MLU data for children between the ages of 18 and 60 months. Leadholm and Miller (1992, abbreviated as LM) reported MLU data for children from 3 to 13 years of ...

Participants were sixteen 5-year-old (eight female, eight male) and sixteen 8-year-old (eight female, eight male) children with typically developing speech, language, and hearing. The average age in the 5-year-old group was 5;5 (range: 60–70 months); it was 8;5 years in the 8-year-old group (range: 96–107 months).

This study reports age-referenced mean length of utterance (MLU) data from children with specific language impairment (SLI) and children without language impairments. Method Of the 306 child participants drawn from a data archive, ages 2;6–9;0 (years;months), 170 were in the SLI group and 136 were in the control group.

One way to measure a child’s language development is by measuring their Mean Length of Utterance (MLU). In this article, we will explore the concept of MLU and its importance in understanding language development. MLU, or Mean Length of Utterance, measures how many words or parts of words your child typically uses when speaking.

Mean length of utterance levels in 6-month intervals for children 3 to 9 years with and without language impairments. Journal of Speech, Language, and Hearing Research , 53(2), 333–349. ASHAWire

– 3 years old: MLU of 2.25-2.75 – 4 years old: MLU of 3.50-4.00 – 5 years old: MLU of 4.00-4.50. A child’s MLU should correlate with their age-appropriate norms to demonstrate typical language development. If the child’s MLU is significantly lower than expected, it may indicate speech or language delays, warranting further evaluation ...

The established norms for MLU by age vary based on the child’s age and language development. According to a study by Brown (1973), the mean length of utterance for a typical 2-year-old is 2.0-2.5 morphemes, and for a 3-year-old, it is 3.0-3.75 morphemes.
