Purpose: In this clinical focus article, we draw attention to the need for immediate intervention shortly after stuttering onset. More than half of stuttering onsets occur before 3 years of age. We argue that existing interventions for preschool children who stutter require varying levels of cognitive engagement from children; hence, they are not suitable for children of that age. For this reason, we argue that there is no clinical trials evidence for treatment efficacy with children younger than 3 years of age. Conclusions: There are many recommended parent strategies that do not require any active participation from children, which, therefore, may be suitable for immediate stuttering intervention. Two of these have laboratory support in their favor: parent speech rate reduction and increased interturn speaker latency. Therefore, we developed a clinical protocol based on those two parent strategies and showed the clinical viability of the protocol with three children who stuttered. We argue that automation of our proposed treatment with lifelike artificial intelligence–generated avatar clinicians will make it globally viable, and a suitable target for future Phases I–IV clinical trials.
