Table 2.

Interrater agreement between the two speech-language pathologist raters for the speech labels that were used to grade the level of speech and voice impairment.

Speech label	1-pt agreement (%)	ICC (95% CI)	Interpretation
Severity	98.4	0.859 [0.769, 0.914]	Good reliability
Intelligibility	93.8	0.814 [0.693, 0.887]	Good reliability
Articulatory	92.2	0.795 [0.654, 0.877]	Good reliability
Phonatory	93.8	0.783 [0.643, 0.868]	Good reliability
Resonatory	92.2	0.536 [0.238, 0.718]	Moderate reliability
Respiratory	89.1	0.631 [0.396, 0.775]	Moderate reliability
Speaking rate	90.6	0.565 [0.281, 0.736]	Moderate reliability
Consistency	57.8	0.195 [−0.323, 0.511]	Poor reliability

Note. Each label was graded using a 5-point Likert scale (i.e., normal, mild, moderate, severe, and profound). ICC = intraclass correlation coefficient; CI = confidence interval.
