Perceptual assessment of cleft speech is at the core of speech methodology in the field of Cleft Lip and Palate. It is the gold standard in providing outcome data for clinical assessment and research to support evidence-based practice in the field. Although there is yet no single internationally and standardized approach, there is a range of specified and internationally agreed upon articulation and non-articulation parameters in cleft palate speech and velopharyngeal dysfunction. Accurate and valid assessment of speech in individuals with a cleft condition also requires a clinical tool that adheres not only to international guidelines but also to the phonetics and the phonology of the spoken language being assessed. The Cantonese-Cleft Speech Assessment Tool (C-CSAT: Yiu, Chan, Choi & Pereira) was published and launched in July 2019.

The aim of this webinar is to equip graduating ST students with knowledge of the tool and how to use the tool correctly, given the complexity of cleft palate/VPI speech and the range of parameters included in a cleft speech assessment protocol. It is assumed that students will have some background and basic knowledge of cleft lip and palate/velopharyngeal insufficiency and associated speech outcomes. On completion of the webinar, each participant will be sent the complete C-CSAT (Yiu et al., 2019) including the photo book and the charting and rating forms.


  • Perceptual speech assessment in Cleft Lip and Palate/VPI speech disorders and speech outcomes
  • Development and construction of the C-CSAT
  • C-CSAT: Speech parameters and measurement method
  • C-CSAT: Speech sampling and protocol
  • Application through case studies

Learning Outcomes

Participants will:
  • Be able to identify and describe the range of speech parameters in the perceptual assessment of CLP speech and/or velopharyngeal insufficiency (VPI)
  • Be able to use some of the more common diacritics in the narrow transcription of cleft palate speech
  • Have an appreciation of the design of the C-CSAT and the nature and type of speech sampling including phonetic content of the C-CSAT
  • Learn about the administration and the speech sampling protocol of the C-CSAT in relation the different speech parameters
  • Learn how to use the charting and rating forms correctly

Biography of Speakers

Ms. YIU Oi Yan, Yoyo is a speech therapist from the Hong Kong Children’s Hospital (HKCH). She received her academic and post-graduate training from the University of Hong Kong (BSc Speech & Hearing Science and M MedSc). She started her speech therapy experience in a pre-school setting prior to joining the Hospital Authority. One of her clinical and research interests is the Cleft Lip and Palate population, with the centralization of pediatric cleft services to the HKCH and her involvement in the development of C-CSAT. Ms. Yiu has a strong collaboration with the medical team in both clinical services and research. Her work on cleft lip and palate has been presented in various local and international conferences.

Ms.CHAN Ching Shun, Sabina is a graduate from the Division of Speech and Hearing Sciences, the University of Hong Kong and is a practising speech therapist. She received a Masters degree in Applied Linguistics and a second Masters degree in Clinical Gerontology where she undertook research in different areas. She has been working in Queen Elizabeth Hospital for many years and recently moved to the Hong Kong Children’s Hospital. She has worked with many patients with a cleft condition in recent years and has the passion to have a standardized reporting and documentation system for cleft palate speech and/or velopharyngeal dysfunction, hence her involvement with the development of C-CSAT.

Ms. CHOI Kai Yan, Cello is a speech therapist from Queen Elizabeth Hospital. She has a Bachelor’s degree from the Department of Linguistics and Modern Languages of CUHK and became a Speech therapist after completing the Master of Speech Therapy programme at the Hong Kong Polytechnic University. There, she had the opportunity to work with clients with a cleft condition within the Cleft Lip and Palate clinic with Dr. Pereira. Ms Choi continues to maintain an interest and passion for cleft speech. Her role in the working group and development of the C-CSAT was around her academic background in phonology and phonetics and her previous clinical speech therapy experiences in the area of cleft lip and palate.

Dr. PEREIRA Valerie Jane is Senior Lecturer with the Division of Speech Therapy, Dept. of Otorhinolaryngology, Head & Neck Surgery (CUHK). She is also an Honorary Assistant Professor with the Faculty of Dentistry , Department of Oral and Maxillofacial Surgery (HKU) as the Speech Therapist for the Joint Cleft & Nasendoscopy Clinics at PPDH. Dr. Pereira has been in the field of Craniofacial conditions and Cleft Lip and Palate for over 15 years. She was previously with the Supra-Regional Craniofacial Unit and subsequently joined the North Thames Regional Cleft Service, both based at Great Ormond Street Hospital for Children NHS Trust in London. She has also undertaken voluntary work in Cleft in Sri Lanka, Uganda, Venezuela and China. She obtained her PhD in Child Health from UCL-ICH (UK) and her work has been published in journals and books. Dr Pereira delivered the Braithwaite Oration at the 12th Indian Society of Cleft Lip, Palate and Craniofacial Society, presented a keynote speech at the 11th World Cleft Congress in Wuhan and most recently, was an invited speaker at the Royal College of SLTs (UK) Cleft Clinical Excellence Network Meeting in London. She is the current Chair of the Craniofacial Dysmorphias and Related Syndromes Committee and is also a Board member of the IALP International Association of Communication Sciences and Disorders.
