The purposes of this study were to investigate naturalness of the post-treatment speech of Comprehensive Stuttering Program (CSP) clients and differences in naturalness ratings by three listener groups. Listeners were 21 student speech-language pathologists, 9 community members, and 15 listeners who stutter. Listeners rated perceptually fluent speech samples of CSP clients obtained immediately post-treatment (Post) and at 5 years follow-up (F5), and speech samples of matched typically fluent (TF) speakers. A 9-point interval rating scale was used. A 3 (listener group)x2 (time)x2 (speaker) mixed ANOVA was used to test for differences among mean ratings. The difference between CSP Post and F5 mean ratings was statistically significant. The F5 mean rating was within the range reported for typically fluent speakers. Student speech-language pathologists were found to be less critical than community members and listeners who stutter in rating naturalness; however, there were no significant differences in ratings made by community members and listeners who stutter. Results indicate that the naturalness of post-treatment speech of CSP clients improves in the post-treatment period and that it is possible for clients to achieve levels of naturalness that appear to be acceptable to adults who stutter and that are within the range of naturalness ratings given to typically fluent speakers.
Readers will be able to (a) summarize key findings of studies that have investigated naturalness ratings, and (b) interpret the naturalness ratings of Comprehensive Stuttering Program speaker samples and the ratings made by the three listener groups in this study.
本研究的目的是调查综合口吃治疗计划（CSP）患者治疗后言语的自然度以及三种听众群体对自然度评分的差异。听众包括 21 名学生言语治疗师、9 名社区成员和 15 名口吃者。听众对 CSP 患者治疗后即刻（Post）和 5 年随访（F5）获得的流畅言语样本以及匹配的典型流利（TF）说话者的言语样本进行了感知流畅性评分。使用 9 点区间评分量表。采用 3（听众群体）x2（时间）x2（说话者）混合方差分析来检验平均评分之间的差异。CSP Post 和 F5 平均评分之间的差异具有统计学意义。F5 的平均评分在典型流利说话者报告的范围内。与社区成员和口吃者相比，学生言语治疗师在评分自然度时的评判标准较低；然而，社区成员和口吃者的评分之间没有显著差异。结果表明，CSP 患者治疗后的言语自然度在治疗后期间有所提高，并且患者有可能达到口吃者和典型流利说话者的自然度评分范围内的自然度水平。
读者将能够（a）总结研究口吃治疗计划患者治疗后言语自然度评分的关键发现，（b）解释综合口吃治疗计划患者样本的自然度评分以及本研究中三个听众群体的评分。
