title: Method of Speech Stimulus Presentation Impacts Pediatric Speech Recognition: Monitored Live Voice Versus Recorded Speech.
abstract: OBJECTIVE
  To characterize the potential differences in speech understanding performance on word and sentence tests assessed using live voice and recorded speech measures for pediatric cochlear implant (CI) recipients.
  
  
  METHODS
  This clinical study used a combination of retrospective and prospective study designs exploring within-subject performance for recorded versus monitored-live-voice presentation methods on pediatric word and sentence measures.
  
  
  METHODS
  Word and/or sentence recognition was obtained for 29 pediatric CI recipients using both recorded stimuli and monitored-live-voice (MLV) within a single-test session with a single experimenter for each session. The difference score was calculated for word and sentence measures allowing a comparison across conditions.
  
  
  METHODS
  Ambulatory.
  
  
  METHODS
  Pediatric patients aged 4 to 17 years.
  
  
  METHODS
  Cochlear implants.
  
  
  METHODS
  Speech recognition testing.
  
  
  RESULTS
  There was a significant difference between recorded and MLV speech understanding with mean recorded word scores being 13-percentage points lower than those obtained via MLV.
  
  
  CONCLUSIONS
  The results of this project suggest that the use of MLV for the assessment of speech perception in the pediatric Audiology clinic may overinflate children's performance and thereby runs the risk of failing to identify poorer or at-risk performance.
