Abstract

Background: This paper examines three methods for providing ratings of within-category detail in children's productions of /s/ and /?/. Method: A group of listeners (n = 61) participated in a rating task in which a forced-choice phoneme identification task was followed by one of three measures of phoneme goodness: visual analog scaling, direct magnitude estimation, or a Likert-scale judgment. Results: All three types of ratings were similarly correlated with sounds' acoustic characteristics. Visual analog scaling and Likert-scale judgments had higher intrarater reliability than did direct magnitude estimation. Moreover, both of them elicited a wider range of judgments than did direct magnitude estimation. Conclusion: Based on our evaluation, Likert-scale judgments and visual analog scaling are equally useful tasks for eliciting within-category judgments. Of these two, visual analog scaling may be preferable because it allows for more distinct levels of response.
