Variability in single-word intelligibility is greater than for multiword intelligibility throughout the age span. For single-word intelligibility, variability is relatively stable after 84 months of age (7 years), with the range between the lowest (5th) and highest (95th) percentiles maintaining about a 20-percentage-point difference.

speech intelligibility by age for single words and for multi-word utterances in English-speaking children between 30 and 47 months based on objectively measured orthographic transcription results from unfamiliar listeners (Hustad, Mahr, Natzke, & Rathouz, 2020). We found that the av-erage 36-month-old child had intelligibility that was only

Gordon-Brannan & Hodson (2000) determined that children above the age of 4;0 with speech intelligibility score below 66% should be considered as candidates for intervention. What this means is that if fewer than 2/3 of the utterances of a child aged 4;0 in conversation with an unfamiliar listener can be understood by that listener, then ...

Speech Intelligibility by Age. In a 2021 study on speech intelligibility in children, Hustad et al. sampled the speech of 538 typically developing children, had a group of 1,076 adults transcribe the speech samples, and used this information to calculate single-word and multi-word intelligibility.

Thus a 4-year-old who is 50% intelligible is considered to be “delayed” by two years. Intelligibility is a much more meaningful measure for young children than are phoneme acquisition normative data, which vary greatly from study to study (see Smit, 1986, for a review of some of the issues related to phoneme acquisition norms).

From ASHA, literacy development info is scattered in among the communication norms, Kdg ... Speech Intelligibility Norms. Developmental ages for intelligibility in different contexts. From Caroline Bowen, ... Age norms for MLU, as well as Brown's 14 grammatical morphemes.

The study of speech intelligibility has received increasing large-scale attention from a developmental perspective. In developing the Test of Children's Speech (TOCS+; Hodge & Daniels, 2007) and establishing its validity, Hodge and Gotzke (2014) examined intelligibility and speaking rate in typically developing English-speaking children (n = 48, ages 3–6 years).

Learn how to measure and improve your child's intelligibility, the extent to which their speech is understood by listeners. Find out the average intelligibility rates by age according to ASHA and other sources, and what factors can affect speech clarity.

There are many variables impacting intelligibility, so no valid norms currently exist. However, here is the best index (developed from more familiar listeners) we can use to guide our goals and expectations for overall intelligible speech in children based on their age: 2 years old: 50% or half of what a child says in conversation is understandable

of age with a linear increase to about 95% by 9 years of age. Standard deviations were reported in this article and generally showed a trend of decreased variability with age. Similarly, Flipsen (2006) examined intelligibility of conversational speech of 320 children between 3 and 8 years of age using speech samples that were transcribed by experts

6. Beyond lab norms: real world intelligibility matters more. Peer-reviewed intelligibility studies conducted in ideal laboratory conditions like those reported in Hustad et al., 2021 are very helpful. But assessing the intelligibility (or unintelligibility) of an individual child requires us to consider a number of factors in addition to norms.

Children make steady progress in intelligibility development through 47 months, and only a small number of children approach 100% intelligibility by this age. Intelligibility continues to develop past the fourth year of life. There is considerable variability among children with regard to intelligibility development.

Intelligibility showed a steep developmental trajectory, with the majority of children obtaining a proportion of intelligible syllables close to 1.0 at the age of 5 years. Articulation rate demonstrated a flatter trajectory, with high variability still within the older children. Disfluencies, on the contrary, occurred only in the youngest children.

ASHA (American Speech-Language-Hearing Association) is an excellent source of reliable information. If your child isn’t displaying several of the skills listed in their age range, schedule an evaluation to determine if therapy is needed.

The age of steepest growth for the 50th percentile was 30–31 months for both single-word and multiword intelligibility and was later for children in lower percentiles. The maximum growth rate was 1.7 intelligibility percentage points per month for single words and 2.5 intelligibility percentage points per month for multiword intelligibility.

Variability in single-word intelligibility is greater than for multiword intelligibility throughout the age span. For single-word intelligibility, variability is relatively stable after 84 months of age (7 years), with the range between the lowest (5th) and highest (95th) percentiles maintaining about a 20-percentage-point difference.

In the first paper (Hustad et al., 2021), we examine speech intelligibility development for single words and connected speech for a large cross-sectional group of children, generating percentile growth curves and quantifying the effects of utterance length on intelligibility by age. In the present article, we examine parallel data on the ...
