Sound Analysis Tool

The KAT helps speech therapists understand children's sound development and set treatment goals. Upload an input sheet with the target words and their child pronunciations. Immediately afterwards, view a detailed analysis.

With the KAT, speech therapists and linguists can accurately and efficiently chart sound development:

Sound acquisition
Which consonants a child already masters, both individually and in clusters.
PCC, PCC-R and PMLU
Measures that give additional information about the accuracy of speech production.
Phonological processes
Which processes occur, and on which sounds.
Group analysis
Compare several test moments of one child, or children with each other.

How does it work?

First, fill in the input sheet with the target words of a naming task, such as the Speechmaker or NAO. You can also enter child pronunciations from spontaneous language. Then you can upload this input sheet, and KAT does the rest: it analyzes the input and provides an Excel analysis that you can download immediately!

Through the E-Learning you can interactively get acquainted with the tool and learn how to use it.

Summary tab

This tab gives a quick overview of the analysis, with a colour-coded overview of the sounds and a table of error types per target sound.

Words tab

This tab lists all entered words, ordered by the initial and final sounds of their syllables.

Percentage correct by sound tab

This tab lists the sounds in order of acquisition. For each sound, it shows how often the child pronounced it correctly. It also holds the PCC, PCC-R and PMLU, and an overview of sound acquisition ordered by place and manner of articulation.

Sounds tab

For each sound, this tab shows whether it was produced correctly and how often it was produced. If the sound was pronounced incorrectly, it shows which process took place (for example deletion, position error or insertion).

Processes tab

This tab lists every phonological process that occurs and the sounds it occurs on. For each phonological process, it also shows how often it occurred in initial and in final position.

Word clusters tab

This tab lists the entered words that contain clusters, ordered by initial and final position.

Percent correct by cluster tab

For each cluster, this tab shows how often the child pronounced it correctly, with initial and final clusters shown separately.

Clusters tab

For each cluster, this tab shows whether it was produced correctly and how often it was produced. If the cluster was pronounced incorrectly, it shows which process took place (for example deletion, position error or insertion).

Processes clusters tab

This tab lists every phonological process that occurs in the clusters and the sounds it occurs on. For each phonological process, it also shows how often it occurred in initial and in final position.

Cycles and patterns tab

This tab lists the sounds ordered according to a Hodson & Paden cycle.

Entry tab

This tab shows the original input: target words, pronunciation, utterance and any notes.

What do others say?

“De KAT biedt een effectieve en snelle analyse voor klanken, zodat je als logopedist aandacht en tijd kan besteden aan daar waar het daadwerkelijk om gaat, kinderen logopedisch helpen tijdens de juiste behandeling.”

“Sinds we de KAT gebruiken, houden we meer tijd over voor waar het echt om draait: de behandeling van het kind. De analyses zijn overzichtelijk en geven direct inzicht in de sterke punten en aandachtspunten. Het vergelijken van verschillende meetmomenten vinden we van grote meerwaarde. Zo maken we de ontwikkeling van een kind zichtbaar en kunnen we ouders op een duidelijke en betrokken manier meenemen in de voortgang.”
