What this trial studies

This study investigates the effectiveness of the Dynamic Temporal and Tactile Cueing (DTTC) treatment for Cantonese-English bilingual children diagnosed with childhood apraxia of speech (CAS). Four children will be recruited and randomly assigned to receive either the English or Cantonese version of DTTC in two separate 6-week treatment phases, with assessments conducted before, during, and after treatment. The children's speech will be evaluated for accuracy in phonemes, stress, and tone, using growth curve analysis to assess treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are Cantonese-English bilingual children aged 3 to 11 years diagnosed with childhood apraxia of speech.

Not a fit: Patients with concomitant developmental disorders or structural abnormalities affecting speech may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly improve speech production in bilingual children with childhood apraxia of speech.

How similar studies have performed: While this specific approach is novel for Cantonese speakers, similar interventions have shown promise in other language contexts.
