PMID 41637265WHAT IT FOUND
A new digital tool for assessing Brazilian Portuguese speech sound disorders showed strong agreement with an established test and reliably distinguished children with disorders from those with typical development.
It is currently validated only for naming and imitation tasks in children aged 4 to 9.
Key findings
01Scores on the new digital instrument's naming and imitation tasks correlated substantially to almost perfectly with the established INFONO test.
02The instrument successfully differentiated between children with phonological disorders and typically developing children across most phonemes.
03Inter-rater agreement for scoring the tasks ranged from moderate to almost perfect, though it was lower than the established INFONO test.

What it does not show
The study only validated the naming and imitation tasks; other parts of the instrument like repetition and diadochokinesis were not tested. The sample was small (45 children) and recruited from public schools and a university clinic, which may not represent all populations. The instrument still requires manual transcription and scoring, so it does not yet save time on interpretation compared to automated tools. There is no normative data for the imitation task in the comparison tool (INFONO), making some comparisons difficult. The study did not include adolescents, despite the instrument being designed for ages 2 to 17.
Declared interests
The study was funded by the National Council for Scientific and Technological Development (CNPq). No conflicts of interest were declared.
The easy way to misread this
Do not assume this digital tool is fully automated or ready for all ages. It currently requires manual transcription, was only tested in children aged 4 to 9, and has not yet been validated for the repetition or diadochokinesis tasks included in the full instrument.
