Understand, detect, and track word-final disfluencies: mostly in children with autism or a neurodevelopmental disorder, sometimes into adolescence or adulthood.
~87%
of autistic children under 12 produce these atypical disfluencies (Autang, 2020)
Word-final
the repetition lands on the rhyme or final syllable, not the onset
Often transient
frequently fades as language matures
Echodysphemia (a term proposed by Brejon Teitler; word-final disfluency in English) is a repetition on the end of the word (agitation-tion, lock-ock) or a mid-syllable vocal interruption with vowel re-release (pa-arents). Broken words are a neighboring phenomenon. Discreet, without tension or awareness, it is seen mostly in children with autism or a neurodevelopmental disorder and often resolves spontaneously; some cases nonetheless persist into adolescence or adulthood, usually with a comorbidity.
Repetition of the end of the word (rhyme, syllable, coda), preceded by a pause
No tension, no struggle, no awareness of the disorder
More frequent in long, complex, or high-interest utterances
Frequent context of autism or a neurodevelopmental disorder
Usually transient, not a priority in young children
The analysis engine detects repetitions on the end of words (echodysphemia) and separates them from word-onset repetitions (stuttering). An objective, in-testing marker to back your clinical ear.
Separates echodysphemia from stuttering (word onset, tension), palilalia (whole words, neurogenic), and logoclonia (last syllable, spasmodic).
For the older child or teenager where the disfluency persists and bothers them: gentle awareness work, without anxiety-provoking correction.
Echodysphemia sits within a broader prosodic profile. Intonation and pausing module for global melody work.
Document change over time: monitor the disfluency rather than over-treating it, in line with the literature.
These atypical disfluencies can prompt a look at pragmatics and social communication. A useful flag, never a diagnosis on its own.

For persistent cases: the older child finally hears what you hear, the basis for a gentle reduction, without anxiety-provoking correction.
Echodysphemia sits within an atypical prosodic profile. A support to work on melody and pause placement.
Segment and settle the rhythm, one chunk at a time, where these disfluencies appear more under load.
1. Detection
Record reading and spontaneous speech. The engine flags word-final repetitions and shows them in the color-coded transcript.
2. Differential
Confirm this is a word-final disfluency (and not stuttering) using the built-in differential.
3. Clinical decision
In young children: monitor, without over-treating. If the disfluency persists and bothers them: consider dedicated work.
4. Self-monitoring
For persistent cases: build awareness gently, aiming to reduce the disfluency without a replacement behavior.
5. Tracking
Document change over time, alongside the core language and communication work.
Structural description of echodysphemia: repetition of the rhyme or final syllable, or vocal interruption with vowel re-release, with the segment preceded by a pause.
Brejon Teitler, N., Ferré, S. & Dailly (2016)
Word-final disfluencies were observed in 72% of a group of children with high-functioning autism, with a profile distinct from stuttering.
Scaler Scott, K. et al. (2014)
Structured Awareness Therapy for Word-Final Disfluency (SAT-WFD) reduces the disfluency without installing a replacement behavior, over short protocols.
Sisskin, V. & Wasilus, S. (2014)
About 87% of autistic children under 12 produce these atypical disfluencies (echodysphemia or broken words), dropping sharply in adolescence.
