International survey on voice quality: Forensic practitioners versus voice therapists
Keywords:
Voice quality, Forensic phonetics, Methodologies, Reliability, International surveyAbstract
In recent years, numerous investigations have focused on voice quality (VQ)
for forensic purposes. These studies notwithstanding, we lack an
international picture of how VQ is generally understood by forensic
practitioners and how it contrasts with the practices of voice therapists. To
fill this gap, a survey was designed and sent to both cohorts: forensicists and
clinicians. A total of 45 responses from 20 countries were received.
Important differences were found between groups, particularly regarding
perceptual assessment. One conclusion to be drawn is that more emphasis
should be placed on calibration and error measurement in forensic
approaches to VQ. Further collaborations with clinicians should also be
encouraged.
