Treatment of Cantonese Speakers With Childhood Apraxia of Speech
- Conditions
- Childhood Apraxia of Speech
- Interventions
- Behavioral: Dynamic Temporal and Tactile Cueing treatment
- Registration Number
- NCT06385470
- Lead Sponsor
- The Hong Kong Polytechnic University
- Brief Summary
The proposed study aims to investigate the efficacy of the Dynamic Temporal and Tactile Cueing treatment in Cantonese-English bilingual speakers with childhood apraxia of speech.
- Detailed Description
Four CE children with CAS will be recruited and receive two versions of the DTTC treatment (i.e., DTTC in English \[DTTC-E\] and DTTC in Cantonese \[DTTC-C\]). After the initial assessment and baseline probe sessions, all the participants will be randomly assigned to receive either DTTC-E or DTTC-C in the first 6-week treatment phase. Then, the between-treatment probe sessions will be conducted during a 2-week washout period. This will be followed by the second 6-week treatment phase, which will be the other version of DTTC. Post-treatment probe sessions will be conducted one week and one month after completion of the second treatment.
Participants' speech productions will be transcribed and evaluated based on their accuracy in phonemes, stress, and tone. Growth curve analysis (Mirman, 2014) will be conducted to examine the group differences in the outcome measures across the treatment sessions.

- Primary Outcome Measures
Name Time Method Stress accuracy Change Before, Between, 1-week and 5-week post DTTC treatment Participants' performance is probe sessions will be transcribed and analysed by an independent research assistant who has experience with Cantonese and English disordered speech will undergo training in phonetic transcription. The training will include practicing transcription of Cantonese and English speech of preschool children on standardized articulation tests. The accuracy of phonemes and the following aspects will be judged by the research assistant.
