The severity of speech impairments can be measured in different ways; whereas some metrics focus on quantifying the specific speech deviations, other focus on the functional effects of the speech impairment, e.g. by rating intelligibility. This report describes the application of a previously untested method to the domain of deviant child speech; an audience response system-based method where listeners’ responses are continuously registered during playback of speech stimuli. 20 adult listeners were given the task of clicking a button whenever they perceived something unintelligible or deviant during playback of child speech stimuli. The untrained listeners’ responses were compared to clinical evaluations of the same speech samples, revealing a strong correlation between the two types of measures. Furthermore, patterns of how listeners’ different experiences influence their clicking responses were explored. Qualitative analysis linking listener clicks to triggering events in the speech samples demonstrates the potential of the click method as an instrument for identification of features in children’s speech that are most detrimental to intelligibility – insights that may have important implications for the selection of speech targets in clinical intervention.
