Effects of mode of presentation and mode of speech on listener perceptions of voice, speech and personality following supracricoid laryngectomy

Paul M Evitts*, Heather Starmer and Kim Webster

Background: There is a paucity of information on listener perceptions of Individuals with a Laryngectomy (IWL) based on different modes of speech, in particular, speech following Supracricoid Laryngectomy (SCL). The purpose of this study was to determine whether listeners have different perceptions of an IWL based on type of surgery, mode of speech, and mode of presentation. 

Methods: 35 naïve listeners (29 female, 6 male, mean age 31.1 years) were randomly presented with recordings of a standard reading passage produced by 15 different speakers (5 modes of speech x 3 speakers each mode) in both audio-only and audio-visual presentation mode. Listeners rated each speaker using a visual analog scale (10 cm line) on factors related to personality, comfort of speech, and voice quality. 

Results: A multivariate Analysis of Variance (MANOVA) showed significant differences in mode of presentation (p<.001), mode of speech (p<.001), and a significant interaction effect between mode of presentation and mode of speech (p<.001). 

Conclusions: Overall results suggest the following: IWL are perceived more favorably in the audio-visual mode; normal laryngeal speakers are perceived more favorably than all modes of alaryngeal speech and esophageal speech was perceived as the least favorable across most of the factors.
