AMPLIFICATION AND AURAL REHABILITATION: PDF OnlyHochberg Irving; Rosen, Stuart; Ball, VirginiaEar and Hearing: June 1989 - p 192-199 Buy Abstract The effect of three levels of text complexity upon connected discourse tracking rates was investigated in normal listeners who tracked by lipreading alone and by lipreading with auditorily presented voice pitch. Text complexity affected connected discourse tracking under both lipreading conditions, with tracking rates decreasing as the level of text complexity increased. The improvement in tracking rate with the addition of voice pitch information was found to be invariant over changes in text complexity when expressed as a simple difference between the two tracking rates. © Williams & Wilkins 1989.
