The REHASP corpus contains sentence prompts repeated several times by a single talker. These recordings can be used to investigate the acoustic variability of natural speech. Version 0.5 of the corpus contains 30 different sentence prompts, each repeated 40 times, for a total of 1200 recordings, all freely available under a permissive license. A larger corpus is in preparation. This document provides meta-information about the REHASP 0.5 database release, including its creation, its contents, and its use.
