Traditional evaluation (TE) of speech intelligibility
Traditional evaluation (TE) of speech intelligibility was measured by
four adult raters. Based on the different degrees of familiarity with
deaf speech, the raters were divided into three different levels: the
level-1 rater is very familiar with the speech spoken by deaf people,
the level-1 rater is marked as SIS1; the level-2 rater
has limited experience with the speech spoken by deaf people, and marked
as SIS2; the level-3 rater has no experience with the
speech spoken by the children with hearing loss, and marked as
SIS3. In our study, the four raters contained two
level-3 raters, one level-1 rater and one level-2 rater.
