Note. Intelligibility difference scores are reported for hybrid stimuli to capture the change in intelligibility relative to conversation. Negative difference scores indicate reduced intelligibility relative to conversation, whereas positive difference scores indicate improved intelligibility relative to conversation. Difference scores for transcription were calculated from overall percent correct scores, whereas difference scores for the scaling task were calculated using scale values averaged across listeners. Bolded cells indicate hybrids for which intelligibility was improved relative to conversation.
