Perceptual Voice Qualities Database (PVQD): Database Characteristics.

OBJECTIVES

To develop a perceptual voice quality database for educational and research purposes.

STUDY

DESIGN

Development of a database.

METHODS

A total of 296 high quality audio file recordings consisting of sustained /a/ and /i/ vowels and sentences from Consensus Auditory-Perceptual Evaluation of Voice were made in clinical environments. Nineteen experienced voice clinicians rated the audio samples using voice qualities from the Consensus Auditory-Perceptual Evaluation of Voice (without visual anchors) and GRBAS scales.

RESULTS

The database includes samples of a wide range of voice quality severities across a wide range of speaker age and sex. Both inter- and intrarater reliabilities were established to be good for the database overall.

CONCLUSIONS

The database is housed in the Mendeley Data online repository and is free for public use.
