The "up" corpus: A corpus of speech samples across adulthood


We describe a speech corpus based on the "Up" series of documentary films by director Michael Apted, showing a set of individuals at seven year intervals over a period of 42 years. The corpus is meant to facilitate phonetic, psycholinguistic and sociolinguistic research on age-related change in speech during young and middle-age adulthood. The corpus contains audio files, transcripts time-aligned at the level of utterance, word, and segment, F0 and vowel formant measurements of portions of the films, featuring eleven participants at ages 21 through 49. The corpus is freely available to researchers upon request.
