q3 i3 Speech intelligibility scores correlated significantly with Ra scores (r(21) = +0.42, p < 0.05) and with Rv scores (r(17) = +0.54, p < 0.01). → Lorin Lachs 2001

Lorin Lachs 2001¶

Lorin Lachs, David B. Pisoni, and Karen Iler Kirk. (2001). Use of Audiovisual Information in Speech Perception by Prelingually Deaf Children with Cochlear Implants. Ear Hear. 2001 June ; 22(3): 236–251. https://www.ncbi.nlm.nih.gov/pmc/

q3 · i3 · associational · r1

Simple bivariate correlations between speech intelligibility (Beginner's Intelligibility Test sentences transcribed by three naïve adult listeners; mean 17.13% words correct, range 2%–45%) and audiovisual gain. The printed effect sizes are r(21) = +0.42 for Ra and r(17) = +0.54 for Rv, the latter exceeding the r ≥ .37 threshold for a large correlation.

"The analysis revealed a significant correlation between the speech intelligibility scores and Ra scores, r(21) = +0.42, p < 0.05. We also observed a significant relationship between speech intelligibility and Rv scores, r(17) = +0.54, p < 0.01."
