TPU Voice Quality database v1
A recorded database of laryngeal voice qualities

A freely downloadable database of speech in 9 laryngeal voice qualities,
recorded by 16 naive (i.e., non-professional) Japanese talkers.

BACKGROUND Voice quality is an important part of human vocal communication. It adds expressivity in both verbal and non-verbal interactions. However, voice quality is still a challenge in human-machine interface technologies.

John Laver (1980) presented a systematic framework to describe voice quality based on auditory impressions and physiological considerations. But as far as we know, there is no widely available multi-talker recording. To help accelerate research on voice quality and its numerous applications, we therefore undertook such a recording, specifically with a chosen subset of laryngeal voice qualities as attempted by naive (non-professional) Japanese native talkers.

The database version 1 includes the voices of 16 Japanese young adults (10 males and 6 females, ages 19-22), reading the same material in 9 laryngeal voice qualities. These voice qualities are nominal, in the sense that each talker tried to produce the intended voice quality as instructed by live demonstrations. However, as the talkers were not professional voice actors, they had varying degrees of success in producing each voice quality. Afterwards, the actually produced voice qualities were auditorily labelled and these labels are also included as part of the database.
