The database, the UCLA Variability Speaker Database, is freely available through UCLA's Box cloud, which can be accessed from our lab website: http://www.seas.ucla.edu/spapl/shareware.html#Data I should mention that the database will also be available from the Linguistic Data Consortium (LDC) as of October, 2021.

 

Here's a brief description of the database.

The UCLA Variability Speaker Database comprises high-quality audio recordings from 202 speakers, 101 men 

and 101 women, performing 12 brief speech tasks in English over three recording sessions (total amount 

of speech: 300-450 sec per speaker). This public database was designed to sample variability in speaking 

within individual speakers and across a large number of speakers. The large set of speakers (similar in age) 

sampled from the current university community is gender-balanced and has a variety of language backgrounds. 

The database can serve as a testing ground for research questions involving between-speaker variability, 

within-speaker variability, and text-dependent variability. 

More details about the database are available in a readme file that can be sent on request.
