Background and Objectives: Normative reference of the connected speech measures (both micro-structural and macro-structural) for descriptive discourse is fundamental to systematic discourse analysis because it provides an anchor for comparison. This study aims to establish a comprehensive normative reference for connected speech measures in Cantonese by analysing a wide array of micro- and macro-structural measures, investigating the impact of age and education on these measures, and examining potential performance differences across various genres of descriptive discourse tasks. Method: The sample included 149 healthy Cantonese-speaking adults who were categorized into three age groups (young, middle-aged, and old) and two education levels (high and low). Speech samples were collected, transcribed, and analysed based on five descriptive discourse tasks in the Cantonese AphasiaBank, including two single-picture descriptions (Flood and Cat rescue), two sequential picture descriptions (Broken window and Refuse umbrella), and one procedural description (Egg and ham sandwich). Results: Normative reference of multiple connected speech measures (such as type, token, noun-verb ratio, Information Content Units [ICU] and Main Concepts [MC]) and lists of standard scoring criteria for the ICU and MC for the five tasks were presented. For age effect, statistical analysis revealed that the old group demonstrated less informativeness and fluency than younger groups across genres. Specifically in procedural description, the middle-aged group showed superior verbal productivity compared to the other groups and informativeness compared to the old group. For education effect, the high-education group outperformed the low-education group in verbal productivity and informativeness across genres. Age-education interaction was found in syntactic complexity measures across genres. Conclusions: These findings contribute to building a comprehensive normative reference for the evaluation of connected speech, providing a complementary tool for systematic and objective assessment.
