Abstract

The current study explored speech social acceptability ratings of adolescents with and without orofacial clefts. The study utilized speech samples previously collected on 80 adolescents, 40 cleft and 40 noncleft, dubbed on to a stimulus tape in a random order. From an earlier study the following were available: (a) adolescent (cleft and noncleft) self-ratings of speech social acceptability, (b) objective ratings of the adolescents' speech social acceptability provided by a listener panel with no background in speech-language pathology. New data were collected by recruiting a new listener panel of 10 graduate students with training in speech-language pathology, utilizing a 7-point bipolar adjective scale. The raters were also asked to indicate which deviant speech parameter led to their negative ratings of social acceptability, selecting from (a) articulation, (b) fluency, (c) nasality, (d) pitch, and (e) voice quality.

Quantitative and qualitative analyses were used to determine results. Inter-and intra-rater reliability were strong (.71 and .75, respectively). No significant difference was found between objective ratings of speech social acceptability provided by an objective panel of raters with no background in speech-language pathology as compared to ratings provided by graduate students with speech-language pathology training (t = -.32, p = .75). Significant difference was found between the adolescents' self-ratings of speech social acceptability and the objective ratings of speech social acceptability provided by graduate students in speech-language pathology (t = 4.87, p = .0001). Cleft adolescents tended to rate their speech more positively than did the trained group of raters. Noncleft adolescents tended to rate themselves similarly to the ratings provided by the trained group of raters.

Qualitative analysis of speech parameter data revealed that nasality, articulation, and voice quality predominantly led to negative social acceptability ratings for the cleft adolescent group. Nasality was the speech parameter most often identified as influencing negative ratings of social acceptability for the cleft group of adolescents. Fluency was most frequently identified as the leading factor for negative social acceptability ratings for the noncleft group of adolescents.
