Does the presence or location of graphic markers affect untrained listeners' ratings of severity of dysphonia?

Objective: To determine the effect of presence and location of severity labels for different types of visual analog scales (VAS) on overall severity (OS) ratings in dysphonic speech.

Study Design: Experimental, between group comparisons.

Methods: Dysphonic and normal voice samples from male and female speakers were presented to inexperienced listeners for judgments of OS.

Effect of fundamental frequency on judgments of electrolaryngeal speech.

Purpose: To determine (a) the effect of fundamental frequency (f₀) on speech intelligibility, acceptability, and perceived gender in electrolaryngeal (EL) speakers, and (b) the effect of known gender on speech acceptability in EL speakers.

Method: A 2-part study was conducted. In Part 1, 34 healthy adults provided speech recordings using electrolarynges set at 75 Hz, 130 Hz, and 175 Hz, and 36 listeners transcribed the recordings.

Listener effort for highly intelligible tracheoesophageal speech.

Unlabelled: The purpose of this study was to determine whether: (a) inexperienced listeners can reliably judge listener effort and (b) whether listener effort provides unique information beyond speech intelligibility or acceptability in tracheoesophageal speech. Twenty inexperienced listeners made judgments of speech acceptability and amount of effort required to listen to 14 male tracheoesophageal speakers using a paired comparison paradigm. Intelligibility was controlled to limit the analysis to the relationship between ratings of listener effort and speech acceptability.
