Perceptual speech assessment is the key to cleft lip and palate (CLP) management in terms of treatment planning, national and international outcome measurement and research. A perceptual clinical assessment framework for cleft speech in Cantonese that meets international standards is warranted and currently being developed.

Speech parameters identified from published and validated frameworks (e.g. Universal set of Parameters for reporting Speech outcomes, Cleft Audit Protocol for Speech‐Augmented) including intelligibility, consonant production, resonance, nasal airflow and grimace, are adopted as core aspect in the assessment framework. Parameters from an international standard set of speech and communication outcomes (International Consortium for Health Outcomes Measurement) are also included for global comparison, including percentage of consonants correct and patient perspective on communication. The speech sampling protocol, whilst adhering to international guidelines, is now undergoing adjustment based on current understanding of Cantonese phonetics, consideration of children’s acquisition of words using Cantonese corpus, and word imageability.

The range of speech outcomes (impairment‐based, functional and person‐centered) will be presented, as well as measurement methods and scaling issues. Samples of the initial speech sampling protocol at single word and sentence levels will be presented. Methods for test validity, reliability and acceptability will be discussed.

A core component of clinical practice is outcome measurement, while perceptual assessment remains the gold standard in CLP. As outcome measurement is necessary for clinical assessment, national and international collaboration and research, it is imperative that any perceptual framework developed is valid, reliable and meets international standards.
