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.

Conditions

Childhood Apraxia of Speech

Outcome Measures

Primary Outcomes (3)

• Phonemes accuracy

  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.

  Change Before, Between, 1-week and 5-week post DTTC treatment

• Stress accuracy

  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.

DTTC treatment

EXPERIMENTAL

Four Cantonese-English bilingual children with be randomly assigned to receive either one of the two versions of DTTC (i.e., DTTC in Cantonese \[DTTC-C\] and DTTC in English \[DTTC-E\]) in the first 6-week treatment phase. Then, there will be a 2-week washout period followed by the second 6-week treatment phase with another version of DTTC.

Behavioral: Dynamic Temporal and Tactile Cueing treatment

Interventions

Dynamic Temporal and Tactile Cueing treatment BEHAVIORAL

DTTC is a motor-based treatment designed for children with CAS who may have limited verbal output. It applies the principles of motor learning and focuses on speech movement gestures in the context of functional words and phrases. The participants will receive two versions of the DTTC treatment (i.e., DTTC in English \[DTTC-E\] and DTTC in Cantonese \[DTTC-C\]), where probe data will be collected before, during, between and after the treatment intervention.
