Groups	Groups, mean±SD		Test result between the two groups
	Speech with feedback (34 people)	Standardized patient (33 people)
Before intervention	31.2±8.4	30.6±7.5	t=−0.3, df=65, P=0.748, independent t-test
After intervention	72.0±10.9	72.2±9.3	t=0.3, df=65, P=0.761, independent t-test
Result of Intergroups test	t=−31.5, df=33, P<0.001, paired t-test	t=34.6, df=32, P<0.001, paired t-test
