Speakers (101 female, 101 male) were recruited from the UCLA university community and represented a variety of language backgrounds. Participants took part in six different tasks: vowel sounds, reading sentences, giving instructions, neutral conversation, happy conversation, a phone conversation, annoyed conversation, and responding to a video. This corpus was designed to sample variability in speaking within individual speakers and across a large number of speakers. UCLA Speaker Variability Database was developed by UCLA Speech Processing and Auditory Perception Laboratory and is comprised of approximately 34 hours of English speech and orthographic transcripts.
