Normative Performance Functions for the Modified Connected Speech Test.
Purpose: The Connected Speech Test (CST) assesses an individual's ability to understand everyday contextualized running speech amidst competing background babble. To minimize accent effects on speech perception scores and reduce the noise floor of the original recordings, an updated version was deve...

To minimize accent effects on speech perception scores and reduce the noise floor of the original recordings, an updated version was developed by Saleh et al. (2020). The updated recordings feature a speaker with a General American accent to replace the Southern U.S. accent in the original test, and modern recording equipment was used to achieve a lower noise floor. The aim of this study was to collect normative data, characterizing performance on the updated CST. Self-reported speech intelligibility and listening effort ratings were collected to examine how subjective perceptions of the task vary across test conditions. Method: To evaluate normative performance on this updated test, 40 native English-speaking adults (36 females and four males) with normal hearing were recruited from The University of Western Ontario. Multitalker babble was presented at a fixed level, and speech was presented at fixed signal-to-babble ratios (SBRs) to participants in both co-located and separated loudspeaker conditions. At each SBR, participants were scored based on key words correctly identified. Subjective speech intelligibility and listening effort were evaluated using self-report scales. For each measure, data were fitted with transfer functions to characterize performance on the task. Results: Participants demonstrated significantly better performance in the separated loudspeaker condition, indicating a spatial release from masking. For both conditions, increased SBR was associated with increased performance and subjective speech intelligibility, and decreased listening effort. Conclusion: The study provides normative data to characterize expected performance for the updated version of the CST. pubtype: Academic Journal doctype: equations & formulas questionnaire/scale research tables/charts randomized controlled trial Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
