Purpose The Computerized Language ANalysis-Index of Productive Syntax (CLAN-IPSyn) system is designed to facilitate automatic computation of the IPSyn measure of productive child syntax. Roberts et al. (2020) conducted a thorough comparison of hand-generated and automatic scores on the Index of Productive Syntax (IPSyn) measure (Scarborough, 1990) and found a high level of error for CLAN-IPSyn. We report on the use of the Roberts et al. analysis to reduce and eliminate errors in CLAN-IPSyn, to improve its accuracy. Method Scores provided by manual and machine scoring of the 20 transcripts used in Roberts et al. (2020) were compared. Divergences in point assignment were examined and significant modifications made to the CLAN-IPSyn program to increase its accuracy. Conclusion The currently available, free version of CLAN at https://talkbank.org is now significantly more correct in terms of exemplars produced, and should assist clinicians and researchers in using the revised IPSyn (Altenberg et al. 2018).

改进自动 IPSyn 编码。

目的计算机化语言分析-生产语法索引 (CLAN-IPSyn) 系统旨在促进自动计算生产子句法的 IPSyn 度量。罗伯茨等。(2020) 对生产句法索引 (IPSyn) 测量（Scarborough，1990）的手动生成分数和自动分数进行了彻底比较，发现 CLAN-IPSyn 的错误率很高。我们报告了 Roberts 等人的使用情况。分析以减少和消除 CLAN-IPSyn 中的错误，以提高其准确性。方法分数由 Roberts 等人使用的 20 个成绩单的手动和机器评分提供。(2020) 进行了比较。检查了点分配中的分歧，并对 CLAN-IPSyn 程序进行了重大修改以提高其准确性。结论 当前可用的 CLAN 免费版本位于 https://talkbank。
