Speech database for classifying different exercises

Our study sample consisted of healthy young adults. Participants were recruited online through the Chinese University of Hong Kong (CUHK) system, and all participants were university students. In total, there were 31 (24 males and 7 females) participants completed the entire study and no one dropped out. Each of them met the following inclusion criteria: 1) College students, 2) no medical history of cardiovascular disease or pulmonary disease. Written consent was obtained from all participants and the ethical approval was obtained from the Survey and Behavioral Research Ethics Committee of CUHK (SBRE-20-219). Participants were asked to read a short text aloud in Cantonese. The text contained four parts, the first part was the well-known speech study text The North Wind And The Sun (Cantonese version). The second part was a text containing nouns that were relatively difficult to pronounce. The third part was three long vowel characters, each of which is asked to be pronounced about three seconds and repeated once. The fourth part was a string of numbers containing different tones of Cantonese, which were also required to be read aloud twice.
