This project describes the composition and goals of the Multisession Audio Research Project (MARP) corpus and some initial experimental findings. The MARP corpus is a three year longitudinal collect of 21 sessions and more than 60 participants. This study was undertaken to test the impact of various factors on speaker recognition, such as inter-session variability, intonation, aging, whispering and text dependency. Initial results demonstrate the impact of sentence intonation, whispering, text dependency and cross session tests. These results highlight the sensitivity of speaker recognition to vocal, environmental and phonetic conditions that are commonly encountered but rarely explored or tested.
